AMSTERDAM— King Willem-Alexander of the Netherlands has completed his final scheduled Boeing 737 flight as a guest pilot for KLM Royal Dutch Airlines (KL), closing a unique chapter in European royal aviation history.
The final flight took place on March 11, 2026, as KLM gradually phased out its Boeing 737 fleet in favor of newer Airbus A321neo aircraft.
The Dutch monarch has maintained active aviation involvement for decades and remains one of the few reigning heads of state to hold advanced pilot certifications.
The transition also signals the end of his regular Boeing 737 operations before retraining on Airbus aircraft.
Dutch King to Pilot KLM A321neo
King Willem-Alexander first obtained his Private Pilot’s Licence in 1985 before earning a Commercial Pilot’s Licence with Instrument Rating in 1987.
His aviation qualifications expanded steadily over the following years, eventually including multi-engine jet authorization, a Military Pilot’s Licence, and an Airline Transport Pilot Licence obtained in 2001.
Before becoming king, Willem-Alexander flew humanitarian missions in Kenya for the African Medical Research & Education Foundation (AMREF) and later supported operations for the Kenya Wildlife Service.
His practical flying experience extended beyond ceremonial aviation and included operational humanitarian work.
The Dutch royal continued flying regularly to maintain proficiency, often operating KLM Cityhopper services and government aircraft alongside professional airline crews.
King Willem-Alexander’s Boeing 737 Transition
King Willem-Alexander qualified on the Boeing 737 in 2017, enabling him to continue operating as a guest pilot after KLM Cityhopper retired its Fokker 70 fleet.
The certification came shortly before the Dutch government introduced a Boeing 737 Business Jet registered as PH-GOV for official state transportation.
KLM’s ongoing fleet modernization programme now centers on the Airbus A321neo, which is gradually replacing older Boeing 737 aircraft across the carrier’s European network. As a result, the Dutch king will now undergo additional training to qualify for Airbus operations.
The Boeing 737 remained a significant part of the monarch’s aviation activity for nearly a decade.
Aviation enthusiasts frequently noted sightings of the king operating scheduled KLM flights departing from Amsterdam Schiphol Airport (AMS), Netherlands.
KLM Fleet Modernization
KLM has accelerated fleet renewal efforts as European airlines increasingly prioritize fuel efficiency and lower emissions.
The Airbus A321neo introduces improved operational economics, quieter engines, and greater seating flexibility compared to older narrowbody aircraft currently in service.
The airline’s transition mirrors broader fleet trends across Europe, where legacy carriers including Lufthansa (LH) and Air France (AF) continue replacing aging short-haul fleets with next-generation aircraft.
KLM’s modernization strategy also aligns with sustainability targets established by the Air France-KLM Group.
The Dutch government aircraft, meanwhile, continues operating independently of KLM’s commercial fleet strategy.
The Boeing 737 Business Jet remains dedicated primarily to official travel for members of the Dutch government and accompanying delegations.
King Willem-Alexander’s continued commitment to pilot training has drawn international attention over the years, particularly because he regularly maintained active line-flying qualifications despite his royal responsibilities.
