2021 will also mark a 50-year anniversary of the B747 Family service with the Dutch carrier.
According to the ch-aviation fleets module, KLM currently operates four B747-400s and a further nine B747-400(M)s. Three of these aircraft are expected to leave the fleet in 2018 according to the Up in the Sky report.
The Dutch flag carrier started retiring its B747-400s in early-2016. Three KLM-owned aircraft of the type are currently stored and await being scrapped at Teruel, while a further one awaits scrapping at Mojave. According to the ch-aviation capacity module, the aircraft are currently deployed on 12 routes out of Amsterdam."
