KLM took delivery of its first Boeing 787-10 on 30 June.
The Dutch carrier will be the first European operator of the variant, it states.
The twinjet – with registration PH-BKA – was greeted by a water cannon salute at Amsterdam Schiphol airport.
It is powered by General Electric GEnx engines and features a special livery to mark KLM’s centenary.
The aircraft will be deployed on services to Kilimanjaro and Dar es Salaam from 2 July, says KLM. It has previously stated that the 787-10 will also serve Dubai and Toronto this year.
The carrier plans to have 15 787-10s in its fleet by 2022 and already has 13 787-9s in service.
It was revealed at the end of June that KLM's Dreamliner backlog will be augmented by six 787s originally allocated to Air France, as part of group-level "fleet optimisation drive" in the 2021-23 timeframe. Seven Airbus A350s originally earmarked for the Dutch operator will instead join its French stablemate's fleet.
