In 1919, a young aviator lieutenant named [[Albert Plesman]] sponsored the ELTA aviation exhibition in [[Amsterdam]]. Attendance at the exhibition was over half a million, and after it closed, several Dutch commercial interests intended to establish a Dutch airline, which Plesman was nominated to head.<ref name=KLMHistoryFU>{{cite journal|journal=International Directory of Company Histories|year=1999|volume=28|title=Koninklijke Luchtvaart Maatschappij, N.V.

The first KLM flight took place on 17 May 1920.

In 1920, KLM carried 440 passengers and 22 tons of freight. In April 1921, after a winter hiatus, KLM resumed its services using [[Fokker F.II]] and [[Fokker F.III]] aircraft.<ref name=KLMHistory /> In 1921, KLM started scheduled services.

In 1930, KLM carried 15,143 passengers. The [[Douglas DC-2]] was introduced on the Batavia service in 1934. The first experimental transatlantic KLM flight was between Amsterdam and [[Curaçao]] in December 1934 using the [[Fokker F.XVIII]] "Snip".<ref name=KLMHistory />

In July 1935 the KLM had three major international passenger flight crashes in one week. The [[1935 Amsterdam Fokker F.XXII crash|"Kwikstaart" crashed]] in Amsterdam on 14 July, the "Maraboe" in [[Bushir]] and on 20 July and the [[1935 San Giacomo Douglas DC-2 crash|“Gaai” crashed]] in [[Pian San Giacomo|San Giacomo]].<ref name=vv1>{{cite web|url=https://www.vergetenverleden.nl/KLM.html|title=Drie KLM vliegrampen in één week|website=vergetenverleden.nl|language=nl|access-date=1 September 2023|archive-date=7 December 2023|archive-url=https://web.archive.org/web/20231207171204/https://www.vergetenverleden.nl/KLM.html|url-status=live}}</ref> The week of 14 to 20 July 1935 is known as the "black week".

The first of the airline's [[Douglas DC-3]] aircraft were delivered in 1936; these replaced the DC-2s on the service via Batavia to [[Sydney Airport|Sydney]]. KLM was the first airline to serve [[Manchester Airport|Manchester's new Ringway airport]], starting in June 1938. KLM was the only civilian airline to receive the [[Douglas DC-5]]; the airline used two of them in the West Indies and sold two to the East Indies government, and is thus the only airline to have operated all Douglas 'DC' models other than the DC-1.

====Second World War====

The outbreak of the [[Second World War]] in September 1939 restricted KLM's operations, with flights over France and Germany prohibited, and many of its aircraft painted in overall orange to limit the potential for confusion with military aircraft. European routes were limited to services to Scandinavia, Belgium and the UK, with flights to Lisbon (bypassing both British and French airspace) starting in April 1940.{{sfn|West ''Air-Britain Archive'' Autumn 2011|p=134}}

When Germany invaded the Netherlands on 10 May 1940, several KLM aircraft—mostly DC-3s and a few DC-2s—were en route to or from the Far East, or were operating services in Europe. Five [[Douglas DC-3|DC-3s]] and one [[Douglas DC-2|DC-2]] were taken to Britain. During the war, these aircraft and crew members flew scheduled passenger flights between Bristol and Lisbon under [[British Overseas Airways Corporation|BOAC]] flight numbers and registration.<ref>{{Cite journal |last=West |first=Michael |date=September 2011 |title=KLM in World War 2 |url=https://air-britain.com/pdfs/archive/Archive_2011.pdf |journal=Air-Britain Archive |volume=32 |issue=3 |page=134 |issn=0262-4923}}</ref>

On 3 March 1942, Douglas DC-3 PH-ALP "''Pelikaan''", then registered as PK-AFV, was [[1942 KNILM Douglas DC-3 shootdown|shot down over Western Australia]] by [[Imperial Japanese Navy Air Service]] [[Mitsubishi A6M Zero]]s during the [[attack on Broome]] while carrying a package of diamonds. The DC-3 crash landed at Carnot Bay, 80 kilometers from Broome. ''Pelikaan'' was subsequently strafed by the Zeros that had shot it down, killing three passengers and the flight engineer. Diamonds worth an estimated  150,000–300,000 [[A£|Australian pounds]] were stolen from the wreckage of the aircraft, and nobody has been convicted of the crime.

Douglas DC-3 PH-ALI "''Ibis''", then registered as G-AGBB, was attacked by the [[Luftwaffe]] on 15 November 1942, 19 April 1943, and finally shot down on 1 June 1943 as [[BOAC Flight 777]], killing all passengers and crew.

Some KLM aircraft and their crews ended up in the Australia-Dutch East Indies region, where they helped transport refugees from Japanese aggression in that area.<ref>{{cite web|date=2019-10-07|title=Celebrating KLM Royal Dutch Airlines 100th Anniversary|url=https://metroairportnews.com/celebrating-klm-royal-dutch-airlines-100th-anniversary/|access-date=2022-02-25|website=Metropolitan Airport News|language=en-US|archive-date=8 March 2022|archive-url=https://web.archive.org/web/20220308154722/https://metroairportnews.com/celebrating-klm-royal-dutch-airlines-100th-anniversary/|url-status=live}}</ref>

After the end of the Second World War in August 1945, KLM immediately started to rebuild its network.

During the immediate post-war period, the Dutch government expressed interest in gaining a majority stake in KLM, thus partially nationalizing it. Plesman wanted KLM to remain a private company under private control; he allowed the Dutch government to acquire a minority stake in the airline.<ref name=KLMHistoryFU /> In 1950, KLM carried 356,069 passengers. The expansion of the network continued in the 1950s with the addition of several destinations in western North America.<ref name=KLMHistoryFU /> KLM's fleet expanded with the addition of new versions of the Lockheed Constellation and [[Lockheed L-188 Electra|Lockheed Electra]], of which KLM was the first European airline to fly.<ref name=KLMHistoryFU />

The [[1973 oil crisis]], which caused difficult economic conditions, led KLM to seek government assistance in arranging debt refinancing. The airline issued additional shares of stock to the government in return for its money. In the late 1970s, the government's stake had again increased to a majority of 78%, effectively re-nationalizing it.<ref name=KLMHistoryFU /> The company management remained under the control of private stakeholders.<ref name=KLMHistory />

In 1980, KLM carried 9,715,069 passengers. In 1983, it reached an agreement with Boeing to upgrade ten of its Boeing 747-200 aircraft (Three 747-200Bs and seven 747-200Ms) with the stretched-upper-deck modification. The work started in 1984 at the Boeing factory in [[Everett, Washington]], and finished in 1986. The converted aircraft were called Boeing 747-200SUD or 747-300, which the airline operated in addition to three newly built Boeing 747-300s manufactured from the ground up.

It did not appear that KLM's longstanding joint venture with Northwest Airlines—which merged with [[Delta Air Lines]] in 2008—was affected by the merger with Air France. KLM and Northwest joined the SkyTeam alliance in September 2004. Also in 2004, senior management came under fire for providing itself with controversial bonuses after the merger with Air France, while 4,500 jobs were lost at KLM. After external pressure, management gave up on these bonuses.<ref>{{Cite web |url=https://www.eurofound.europa.eu/publications/article/2004/klm-senior-managers-forgo-controversial-bonuses |title=KLM senior managers forgo controversial bonuses |publisher=Eurofound |access-date=21 June 2023 |archive-date=21 June 2023 |archive-url=https://web.archive.org/web/20230621043212/https://www.eurofound.europa.eu/publications/article/2004/klm-senior-managers-forgo-controversial-bonuses |url-status=live }}</ref>

===Branding===
[[Dirk Roosenburg]] designed the KLM logo at its establishment in 1919; he intertwined the letters K, L, and M, and gave them wings and a [[Crown of the Netherlands|crown]]. The crown was depicted to denote KLM's royal status, which was granted at KLM's establishment.<ref>{{cite web|title=KLM keeps predicate 'Royal'|url=https://www.klm.com/travel/nl_en/about/news_press/travel_news/KLM_keeps_predicate_Royal.htm|publisher=KLM|access-date=2 February 2013|url-status=dead|archive-url=https://web.archive.org/web/20130620024812/https://www.klm.com/travel/nl_en/about/news_press/travel_news/KLM_keeps_predicate_Royal.htm|archive-date=20 June 2013}}</ref> The logo became known as the "vinklogo" in reference to the [[common chaffinch]].<ref>{{cite book|last=van Hoogstraten|first=Dorine|title=Dirk Roosenburg, architect 1887–1962|year=2005|trans-title=Dirk Roosenburg, architect 1887–1962|publisher=010 Publishers |location=Rotterdam |isbn=9064505322 |url=https://books.google.com/books?isbn=9064505322|access-date=2 February 2013|page=137|language=nl|trans-chapter=Buildings for aviation|chapter=Gebouwen voor de luchtvaart}}</ref> The KLM logo was largely redesigned in 1961 by [[F.H.K.

KLM has utilized several major liveries since its founding, with numerous variations on each. Initially, many aircraft featured a bare-metal fuselage with a stripe above the windows bearing the phrase "The Flying Dutchman". The rudder was divided into three segments and painted to match the Dutch flag. Later aircraft types sometimes bore a white upper fuselage, and additional detail striping and titling. In the mid-1950s, the livery was changed to feature a split cheatline in two shades of blue on a white upper fuselage and angled blue stripes on the vertical stabilizer. The tail stripes were later enlarged and made horizontal, and the then-new crown logo was placed in a white circle. The final major variation of this livery saw the vertical stabilizer painted completely white with the crown logo in the center. All versions of this livery had small "KLM Royal Dutch Airlines" titles, first in red, and later in blue.<ref>{{Cite web |title=» The new KLM livery: an in-depth look at all the changes |url=https://www.norebbo.com/new-klm-livery/ |access-date=2023-09-06 |language=en-US |archive-date=6 September 2023 |archive-url=https://web.archive.org/web/20230906164603/https://www.norebbo.com/new-klm-livery/ |url-status=live }}</ref>

Since 1971, the KLM livery has primarily featured a bright blue fuselage, with variations on the striping and details. Originally a wide, dark blue cheatline covered the windows and was separated from the light grey lower fuselage by a thin white stripe. The KLM logo was placed centrally on the white tail and the front of the fuselage. In December 2002, KLM introduced an updated livery in which the white strip was removed and the dark-blue cheatline was significantly narrowed. The bright blue colour was retained and now covers most of the fuselage. The KLM logo was placed more centrally on the fuselage while its position on the tail and the tail design remained the same.<ref>{{cite press release|title=New Livery For KLM Fleet |url=http://www.presslink.nl/klm/|publisher=KLM|date=20 December 2002|access-date=9 February 2013 |archive-url=https://web.archive.org/web/20021222090350/http://www.presslink.nl/klm/ |archive-date=22 December 2002}}</ref> In 2014, KLM modified its livery with a swooping cheatline that wraps around the entire forward fuselage. The livery was first introduced on [[Embraer 190]]s.<ref>{{cite press release |author=<!--Staff writer(s); no by-line.--> |title=KLM Welcomes its Latest Embraer 190 and Modified Livery |url=http://news.klm.com/klm-welcomes-its-latest-embraer-190-and-modified-livery |location=Amstelveen |date=29 April 2014 |access-date=2 July 2015 |archive-date=2 July 2015 |archive-url=https://web.archive.org/web/20150702221139/http://news.klm.com/klm-welcomes-its-latest-embraer-190-and-modified-livery |url-status=live }}</ref>

In April 2010, KLM introduced new uniforms for its female cabin attendants, ground attendants and pilots at KLM and KLM Cityhopper. The new uniform was designed by Dutch couturier [[Mart Visser]]. It retains the KLM blue colour that was introduced in 1971 and adds a touch of orange—the national colour of the Netherlands.<ref>{{cite press release|title=KLM introduces new ladies uniform|url=http://nieuws.klm.com/klm-introduceert-nieuw-damesuniform-en/|publisher=KLM|date=14 April 2010|access-date=9 February 2013|archive-date=20 June 2013|archive-url=https://web.archive.org/web/20130620030208/http://nieuws.klm.com/klm-introduceert-nieuw-damesuniform-en/|url-status=live}}</ref>

In August 2024, KLM introduced a brand new livery on its first [[Airbus A321neo]] with the blue section now fully covers the nose dome and the [[SkyTeam]] logo together with the [[Air France–KLM|Air France-KLM Group]] logo moved from the nose section to the tail section.<ref>{{Cite web |title=KLM reveals new A321neo livery |url=https://news.klm.com/klm-reveals-new-a321neo-livery/ |access-date=2025-03-27 |website=KLM reveals new A321neo livery |language=en}}</ref> The logo and the font has also been changed slightly for a more modernized feel.

KLM has an extensive presence on [[social media]] platforms and also runs a blog.<ref>{{cite web |title=Where to find KLM on social media sites |url=http://www.klm.com/travel/nl_en/plan_and_book/klm_on_social_media/where_to_find_us/index.htm |publisher=KLM |access-date=31 March 2013 |archive-date=27 May 2013 |archive-url=https://web.archive.org/web/20130527135234/http://www.klm.com/travel/nl_en/plan_and_book/klm_on_social_media/where_to_find_us/index.htm |url-status=dead }}</ref> Customers can make inquiries through these channels.

The airline's use of social media platforms to reach customers peaked when the Icelandic volcano [[Eyjafjallajökull]] erupted in April 2010, causing widespread disruption to air traffic. Customers used the social networks to contact the airline, which used them to provide information about the situation.<ref>{{cite web |last=van Drimmelen |first=Jochem |title=KLM's social media strategy – Part 1 |url=http://blog.klm.com/klm%E2%80%99s-social-media-strategy-part-1/4670/ |publisher=KLM Blog |access-date=31 March 2013 |url-status=dead |archive-url=https://web.archive.org/web/20120728021256/http://blog.klm.com/klm%E2%80%99s-social-media-strategy-part-1/4670/ |archive-date=28 July 2012 }}</ref> Following the increased use of social media, KLM created a centralized, public social media website named the Social Media Hub in October 2010.<ref>{{cite web |last=van Drimmelen |first=Jochem |title=KLM's social media strategy – Part 2 |url=http://blog.klm.com/klm%E2%80%99s-social-media-strategy-part-2/4700/ |publisher=KLM Blog |access-date=31 March 2013 |url-status=dead |archive-url=https://web.archive.org/web/20130329234633/http://blog.klm.com/klm%E2%80%99s-social-media-strategy-part-2/4700/ |archive-date=29 March 2013 }}</ref>

KLM has developed several services based on these social platforms, including:
* ''Meet & Seat''; this service allows passengers to find information about people who will be on the same KLM flight by connecting their Facebook or LinkedIn profiles to the flight. Meet & Seat facilitates contact with fellow travellers who have the same background or interests.<ref>{{cite web |title=KLM Meet & Seat |url=http://www.klm.com/travel/nl_en/prepare_for_travel/on_board/Your_seat_on_board/meet_and_seat.htm |publisher=KLM |access-date=31 March 2013 |archive-date=3 April 2013 |archive-url=https://web.archive.org/web/20130403115450/http://www.klm.com/travel/nl_en/prepare_for_travel/on_board/your_seat_on_board/meet_and_seat.htm |url-status=dead }}</ref> By launching Meet & Seat, KLM became the first airline to integrate social networking into its regular flight process.<ref>{{cite press release |title=With Meet & Seat, KLM integrates social media with air travel |url=http://nieuws.klm.com/klm-lanceert-applicatie-meet-e-seat-en/ |publisher=KLM |date=3 February 2012 |access-date=31 March 2013 |archive-date=28 May 2013 |archive-url=https://web.archive.org/web/20130528184732/http://nieuws.klm.com/klm-lanceert-applicatie-meet-e-seat-en/ |url-status=live }}</ref>

In June 2013, KLM launched its own 3D strategy game "Aviation Empire" for [[iOS]] and [[Android (operating system)|Android]] platforms. The game allows users to experience airline management. Players manage KLM from its establishment until the present; they can invest in a fleet, build a network with international destinations and develop airports. The game combines the digital world with the real world by enabling the unlocking of airports by [[GPS]] check-ins.<ref>{{cite press release |title=KLM Launches 3D Strategy Game 'Aviation Empire' |url=http://nieuws.klm.com/klm-lanceert-3d-strategy-game-aviation-empire-en/ |publisher=KLM |date=27 June 2013 |access-date=10 July 2013 |archive-date=1 July 2013 |archive-url=https://web.archive.org/web/20130701171800/http://nieuws.klm.com/klm-lanceert-3d-strategy-game-aviation-empire-en/ |url-status=live }}</ref>

===Philanthropy===
KLM started KLM AirCares, a program that aids underprivileged children in developing countries to which KLM flies, in 1999.<ref>{{cite web |url=http://corporate.klm.com/en/topics/klm-aircares |title="KLM AirCares" KLM Website |publisher=Corporate.klm.com |access-date=29 November 2012 |archive-date=6 December 2010 |archive-url=https://web.archive.org/web/20101206210307/http://corporate.klm.com/en/topics/klm-aircares |url-status=live }}</ref> The airline collects money and airmiles from passengers. In 2012, new applications for support from the program were suspended because it needed an overhaul.<ref>{{cite web|url=http://www.klm.com/corporate/en/topics/klm-aircares/index.html|title=KLM AirCares|access-date=1 July 2014|archive-date=17 June 2014|archive-url=https://web.archive.org/web/20140617131042/http://www.klm.com/corporate/en/topics/klm-aircares/index.html|url-status=live}}</ref>

==Fleet==
{{Main|KLM fleet}}

===Fleet strategy===

Passengers in Europe Business Class are served either a cold meal, a hot main course, or a three-course meal depending on the duration of the flight.<ref>{{cite web|title=Dining in Business Class|url=http://www.klm.com/travel/nl_en/prepare_for_travel/on_board/dining_on_board/dining_in_business_class.htm|publisher=KLM|access-date=25 January 2013|archive-date=27 January 2013|archive-url=https://web.archive.org/web/20130127034546/http://www.klm.com/travel/nl_en/prepare_for_travel/on_board/dining_on_board/dining_in_business_class.htm|url-status=live}}</ref> All chicken served in World and Europe Business Class meets the standards of the Dutch Beter Leven Keurmerk (Better Life Quality Mark).<ref>{{cite press release|title=KLM Takes New Steps Towards More Sustainable Catering|url=http://nieuws.klm.com/klm-zet-verdere-stappen-in-duurzame-catering-en/|publisher=KLM|date=1 October 2012|access-date=25 January 2013|archive-date=5 January 2013|archive-url=https://web.archive.org/web/20130105015800/http://nieuws.klm.com/klm-zet-verdere-stappen-in-duurzame-catering-en/|url-status=live}}</ref> KLM partnered with Dutch designer [[Marcel Wanders]] to design the tableware of World and European Business Class.<ref>{{cite press release|title=KLM's World Business Class services van ontwerper Marcel Wanders|url=http://nieuws.klm.com/klm-a-s-world-business-class-servies-van-ontwerper-marcel-wanders/|publisher=KLM|date=9 November 2010|language=nl|trans-title=KLM's World Business Class tableware from designer Marcel Wanders|access-date=25 January 2013|archive-url=https://web.archive.org/web/20130402232012/http://nieuws.klm.com/klm-a-s-world-business-class-servies-van-ontwerper-marcel-wanders/|archive-date=2 April 2013|url-status=dead}}</ref>

Economy Class passengers on long-haul flights are served a hot meal and a snack, and a second hot meal or breakfast, depending on the duration of the flight. On short-haul flights, passengers are served sandwiches or a choice of sweet or savoury snack, depending on the duration and time of the day.

===Delft Blue houses===
{{see also|List of KLM Delft Blue houses}}
[[File:KLM DelftBlueHouses.PNG|left|thumb|KLM Delft blue houses]]

Since the 1950s, KLM has presented its World Business Class passengers with a [[Delft blue]] miniature traditional Dutch house.<ref name="kingdom">Zegeling, Mark (2015). ''Little Kingdom by the Sea: a Celebration of Dutch Cultural Heritage – Secrets of the KLM Houses Revealed''. Markmedia & Art. {{ISBN|9081905627}}.</ref> These miniatures are reproductions of real Dutch houses and are filled with Dutch [[genever]].<ref name=KLMHouses>{{cite web |title=KLM Delft Blue houses |url=http://www.klm.com/travel/nl_en/prepare_for_travel/on_board/travel_classes/miniatures.htm |work=KLM |access-date=25 July 2013 |archive-date=31 July 2013 |archive-url=https://web.archive.org/web/20130731105828/http://www.klm.com/travel/nl_en/prepare_for_travel/on_board/travel_classes/miniatures.htm |url-status=live }}</ref> Initially the houses were filled with [[Bols (brand)|Bols]] liqueur, which in 1986 was changed to Bols young genever.<ref>{{cite web|title=House of Bols|url=http://www.bols.com/2011/11/17/in-pellentesque/|work=Bols|access-date=25 July 2013|archive-url=https://web.archive.org/web/20181215224444/https://bols.com/2011/11/17/in-pellentesque|archive-date=15 December 2018|url-status=dead}}</ref>

In 1952, KLM started to give the houses to its First Class passengers. With the elimination of First Class in 1993, the houses were handed out to all Business Class passengers.<ref name=WSJHouses>{{cite news|last=Michaels|first=Daniel|title=The Ultimate Dutch Status Symbol: House-Shaped Booze Bottles; Jet-Setters Hoard, but Avoid Drinking, KLM's Freebies; The $1,000 Cheese Building|url=https://www.wsj.com/articles/SB121217604543933443|access-date=25 July 2013|newspaper=The Wall Street Journal|date=31 May 2008|archive-date=17 March 2015|archive-url=https://web.archive.org/web/20150317002145/http://www.wsj.com/articles/SB121217604543933443|url-status=live}}</ref> The impetus for these houses was a rule aimed at curtailing a previously widespread practise of offering incentives to passengers by limiting the value of gifts given by airlines to US$0.75. KLM did not bill the Delft Blue houses as a gift but as a last drink free of charge, which was served in the house.<ref name=WSJHouses /><ref>{{cite web |title=Discover all our houses; About KLM Houses |url=http://www.klm.com/travel/nl_en/prepare_for_travel/on_board/travel_classes/klmhouses.htm |work=KLM |access-date=25 July 2013 |archive-date=2 August 2013 |archive-url=https://web.archive.org/web/20130802034918/http://www.klm.com/travel/nl_en/prepare_for_travel/on_board/travel_classes/klmhouses.htm |url-status=live }}</ref>

Every year, a new house is presented on 7 October, the anniversary of KLM's founding in 1919.<ref name=KLMHouses /> The number on the last-presented house thus represents the number of years KLM has been in operation. Special edition houses—the [[Royal Palace of Amsterdam]] and the 17th century Cheese Weighing House ''De Waag'' in [[Gouda, South Holland|Gouda]]—are offered to special guests, such as VIPs and honeymoon couples.<ref name=WSJHouses />

===Ground services===
KLM offers various check-in methods to its passengers, who can check in for their flights at self-service check-in kiosks at the airport, via the Internet, or a mobile telephone or tablet. At destinations where these facilities are not available, check-in is by an airline representative at the counter.<ref>{{cite web|url=http://www.klm.com/travel/nl_en/prepare_for_travel/checkin_options/all_about/index.htm|title=All about checking in|publisher=KLM|access-date=19 January 2013|archive-date=23 January 2013|archive-url=https://web.archive.org/web/20130123103757/http://www.klm.com/travel/nl_en/prepare_for_travel/checkin_options/all_about/index.htm|url-status=live}}</ref> Electronic boarding passes can be received on a mobile device while boarding passes can be printed at airport kiosks.<ref>{{cite web |title=Receiving your boarding pass |url=https://www.klm.com/information/airport/boarding-pass |access-date=2023-11-27 |website=KLM |archive-date=9 December 2023 |archive-url=https://web.archive.org/web/20231209003919/https://www.klm.com/information/airport/boarding-pass |url-status=live }}</ref>

Since 4 July 2008 KLM, in cooperation with Amsterdam Airport Schiphol, has been offering self-service baggage drop-off to its passengers. The project started with a trial that included one drop-off point.<ref>{{Cite news |date=December 15, 2006 |title=Six new Self-Service Baggage Drop-Off units now in use at Amsterdam Airport Schiphol |work=news.schiphol.com |url=https://news.schiphol.com/six-new-self-service-baggage-drop-off-units-now-in-use-at-amsterdam-airport-schiphol/ |url-status=live |access-date=2023-11-27 |archive-url=https://web.archive.org/web/20130526174839/http://www.schiphol.nl/SchipholGroup/NewsMedia/PressreleaseItem/AmsterdamAirportSchipholSixNewSelfServiceBaggageDropOffUnitsNowInUseAtAmsterdamAirportSchiphol1.htm |archive-date=26 May 2013}}</ref> The number of these points has gradually increased; {{as of|2012|2|8|lc=y}} there are 12 of them.<ref>{{Cite news |date=July 4, 2008 |title=Amsterdam airport trials self-service baggage check |work=[[Reuters]] |url=https://www.reuters.com/article/us-dutch-airport-idUSL0430176320080704/ |access-date=2023-11-27 |archive-date=18 November 2023 |archive-url=https://web.archive.org/web/20231118021259/https://www.reuters.com/article/us-dutch-airport-idUSL0430176320080704/ |url-status=live }}</ref> KLM passengers can now drop off their bags themselves. Before they are allowed to do that they are being checked by a KLM employee.

In November 2012, KLM started a pilot scheme at Amsterdam Airport Schiphol to test self-service boarding. Passengers boarded the aircraft without any interference of a gate agent by scanning their [[boarding pass]]es, which opened a gate. KLM partner airline Air France ran the same pilot at its hub at [[Paris-Charles de Gaulle Airport]]. The pilot ran until March 2013, which was followed by an evaluation.<ref>{{cite web|title=KLM test 'self service boarding' op Schiphol en Parijs CDG |url=http://www.luchtvaartnieuws.nl/nl-NL/Article.cms/Airlines/KLM_test_self_service_boarding_op_Schiphol_en_Parijs_CDG |work=Luchtvaartnieuws |date=30 November 2012 |publisher=Reismedia |language=nl |trans-title=KLM tests 'self service boarding' at Schiphol and Paris CDG |access-date=28 February 2013}}</ref>

KLM is the first airline to offer self-service transfer kiosks on its European and intercontinental routes for passengers connecting through Amsterdam Airport Schiphol.<ref>{{Cite news |date=2006-12-15 |title=KLM Royal Dutch Airlines to introduce self-service transfer kiosks |work=Business Travel News Europe |url=https://www.businesstravelnewseurope.com/Air-Travel/KLM-Royal-Dutch-Airlines-to-introduce-self-service-transfer-kiosks |access-date=2023-11-27 |archive-date=6 June 2023 |archive-url=https://web.archive.org/web/20230606172309/https://www.businesstravelnewseurope.com/Air-Travel/KLM-Royal-Dutch-Airlines-to-introduce-self-service-transfer-kiosks |url-status=live }}</ref> The kiosks enable connecting passengers to view flight details of connecting flights, to change seat assignments or upgrade to a more comfortable seat. When a passenger misses a connecting flight, details about alternative flights can be viewed on the kiosk and a new boarding pass can be printed. Passengers who are entitled to coupons for a beverage, meal, the use of a telephone, or a travel discount can have these printed at the kiosk.<ref>{{cite web|url=http://www.klm.com/travel/nl_en/prepare_for_travel/at_the_airport/connections/index.htm#3|title=Transfer to another flight|publisher=KLM|access-date=19 January 2013|archive-date=25 January 2013|archive-url=https://web.archive.org/web/20130125080526/http://www.klm.com/travel/nl_en/prepare_for_travel/at_the_airport/connections/index.htm#3|url-status=live}}</ref>

===Flying Blue===
{{Redirect|Flying Blue|the racehorse|Flying Blue (horse)}}
Air France-KLM's [[frequent flyer program]], Flying Blue, awards miles based on the distance travelled, ticket fare and class of service. As well as KLM and [[Air France]], other airlines that adopted the Flying Blue programme include [[Transavia]], [[Aircalin]], and [[TAROM]]. Membership in the program is free. When flying, members earn Experience Points (XP) and Award Miles.<ref>{{cite web|url=https://www.flyingblue.com/en/programme?activeTab=introduction|title=The Flying Blue programme|publisher=Flying Blue|access-date=2 July 2023|archive-date=2 July 2023|archive-url=https://web.archive.org/web/20230702113341/https://www.flyingblue.com/en/programme?activeTab=introduction|url-status=live}}</ref>

Experience Points are used to determine membership level and remain valid until the end of the qualification period, which lasts for 1 year from counting from the member's first flight. XP can be earned with KLM, Air France, Transavia, Aircalin, TAROM, and other SkyTeam partners. The Flying Blue programme is divided into four tiers: Explorer, Silver (SkyTeam Elite), Gold (SkyTeam Elite Plus) and Platinum (SkyTeam Elite Plus). The membership tier depends on the number of Experience Points earned and is recalculated each qualification period. Flying Blue privileges are additive by membership tier; higher tiers include all benefits listed for prior tiers. There is an additional fifth tier, Platinum for Life, which can be obtained after 10 consecutive years of Platinum membership. After the Platinum for Life status is obtained, re-qualification is not required.<ref>{{cite web|url=https://www.flyingblue.com/en/programme/more-info/status|title=Status & XP|publisher=Flying Blue|access-date=2 July 2023|archive-date=2 July 2023|archive-url=https://web.archive.org/web/20230702113344/https://www.flyingblue.com/en/programme/more-info/status|url-status=live}}</ref>

==Sustainability==
In 2022, parent company Air France-KLM published a report of emission reduction targets for 2030 that were approved by the [[Science Based Targets initiative]] to be in line with the [[Paris Agreement]].<ref name=":0" /> This includes offering options for consumers to contribute to sustainability programs offered by the airline. On their website, KLM detail many sustainability initiatives, including use of sustainable aviation fuels, reforestation programs, and reducing the weight of on board items to save fuel.<ref name=":1" /> 

A report by the [[Breda University of Applied Sciences]] stated that the measures set by KLM in the 2022 report will not achieve the targets set out.<ref name=":2">{{cite book |last1=Peeters |first1=Paul |url=https://pure.buas.nl/ws/portalfiles/portal/32555525/Peeters_Buijtendijk_Eijgelaar_ExpertReport_v4_Final.pdf |title=KLM, science based targets, and the Paris Agreement – Expert Report |last2=Buijtendijk |first2=Harald |last3=Eijgelaar |first3=Eke |date=4 December 2023 |publisher=Breda University of Applied Science |language=en |access-date=21 December 2024}}</ref> In 2024, it was ruled that 15 of 19 claims submitted by KLM, including being on their way to "a more sustainable future" were based on vague and general statements, and overexaggerated the potential effects of the measures put in place. These were deemed misleading and therefore unlawful, and has been described by activists as [[Greenwashing]].<ref>{{cite web |last=Duurzaam-ondernemen |date=20 March 2024 |title=Rechtbank: 'KLM doet aan greenwashing' |url=https://www.duurzaam-ondernemen.nl/rechtbank-klm-doet-aan-greenwashing/ |access-date=21 December 2024 |website=www.duurzaam-ondernemen.nl |publisher=Duurzaam Ondernemen |language=nl |location=}}</ref>

Meanwhile, Air France-KLM have been heavily involved in lobbying against European climate policy, and have actively opposed measures such as a kerosine tax and a flight cap at Schiphol Airport.<ref>{{cite news |author=<!-- not stated --> |date=1 December 2023 |title=Air France-KLM's Climate Policy Engagement |url=https://influencemap.org/site/data/000/025/Air-France-KLM_Investor-Briefing_Dec_2023.pdf |access-date=12 December 2024 |work=Influencemap Report |publisher=Influencemap |location=}}</ref>

===Sustainable Aviation Fuels===
The main measure mentioned by KLM in its emissions reduction programme is the addition of [[Sustainable Aviation Fuel]]s (SAF) to jet fuel. KLM offers customers the option to pay extra to contribute to the SAF programme, stating that the fuel will be added to the system at Schipol.<ref>{{Cite web |author = <!-- not stated -->| url = https://www.klm.nl/information/sustainability/sustainable-aviation-fuel#add-saf-to-your-booking| title  = SAF aan uw boeking toevoegen| access-date = 21 December 2024| publisher  = KLM| language = NL}}</ref> The report by [[Breda University of Applied Sciences|Breda University]] stated that KLM's target for SAF share by 2030 was not realistic given the scarcity of the fuel and the expected global availability.<ref name=":2" />

===Compensation through reforestation===
KLM offers customers the opportunity to offset their flight emissions by contributing to reforestation programs. They initially used the slogan “Be a hero, fly CO<sub>2</sub> zero” to promote this. However in 2022, the Dutch agency RCC (Advertising Code Committee) indicated to KLM that this claim was not sufficiently substantiated and that it was wrong to state that it was possible to fly CO<sub>2</sub> neutral.<ref>{{Cite web|title="02021/00553"|access-date=2024-12-24|date=2022-04-08|publisher=Stichting Reclame Code|language=nl|url=https://www.reclamecode.nl/uitspraak/?uitspraakId=338478}}</ref>

[[File:KLM Boeing 747-200 PH-BUF (7491686916).jpg|thumb|At the time of the accident, the [[Boeing 747]] named ''Rhine'' was only six years old.]]

The Tenerife disaster, which occurred on 27 March 1977, remains the accident with the highest number of airliner passenger fatalities, as well as the most recent fatal and notable incident involving a KLM aircraft. 583 people died when a KLM [[Boeing 747-200B]] attempted to take off without clearance and collided with a taxiing [[Pan American World Airways|Pan Am]] [[Boeing 747-100]] at [[Los Rodeos Airport]] on the [[Canary Island]] of [[Tenerife]], [[Spain]]. No one on the KLM 747 survived (14 crew, 234 passengers were killed) while 61 of the 396 passengers and crew on the Pan Am aircraft survived. Pilot error from the KLM aircraft was the primary cause. Owing to a communication misunderstanding, the KLM captain thought he had clearance for takeoff.<ref name="Tonyleather">{{cite web |last=Hamilton |first=Sophia |date=2023-09-29 |title=Top 10 Reasons for Plane Crashes |url=https://airlinespolicy.com/blog/top-10-reasons-for-plane-crashes/ |access-date=2023-11-25 |archive-date=25 November 2023 |archive-url=https://web.archive.org/web/20231125120308/https://airlinespolicy.com/blog/top-10-reasons-for-plane-crashes/ |url-status=live }}</ref><ref>{{cite web|last=Sebastien Freissinet|title=The Tenerife crash-March 27th, 1977|url=http://www.1001crash.com/index-page-tenerife-lg-2.html|access-date=7 May 2012|archive-date=11 April 2022|archive-url=https://web.archive.org/web/20220411111436/https://www.1001crash.com/index-page-tenerife-lg-2.html|url-status=live}}</ref> Another cause was dense fog, meaning the KLM flight crew was unable to see the Pan Am aircraft on the runway until immediately before the collision.<ref name=ASN>{{cite web|title=ASN Accident Description|url=https://asn.flightsafety.org/asndb/329179|website=Aviation Safety Network|access-date=26 November 2015|archive-date=2 April 2011|archive-url=https://web.archive.org/web/20110402172426/http://aviation-safety.net/database/record.php?id=19770327-0|url-status=live}}</ref> The accident had a lasting influence on the industry, particularly in the area of communication. An increased emphasis was placed on using standardized phraseology in air traffic control (ATC) communication by both controllers and pilots alike, thereby reducing the chance for misunderstandings. As part of these changes, the word "takeoff" was removed from general usage, and is only spoken by ATC when clearing an aircraft to take off.<ref>{{cite web|url=http://www.tenerife-information-centre.com/tenerife-airport-disaster.html|title=The Tenerife Airport Disaster – the worst in aviation history|work=The Tenerife Information Centre|access-date=29 October 2014|archive-date=11 April 2022|archive-url=https://web.archive.org/web/20220411111410/https://www.tenerife-information-centre.com/tenerife-airport-disaster.html|url-status=live}}</ref>
