Scandinavian operator TUI Nordic has taken delivery of its first Boeing 737 Max, the second to be received by the tourism group.
The airline conducted the Max 8 delivery flight – from Seattle to Stockholm – using a 30% blend biofuel.
"This was one of the most carbon-efficient flights ever accomplished by this aircraft type," claims the carrier. TUI previously collaborated with Boeing on its 'ecoDemonstrator' programme, which included biofuel testing.
TUI introduced its first 737 Max a month ago when the initial jet was delivered to its Brussels-based division TUI Belgium.
Seventy-two aircraft, a mix of Max 8s and Max 10s, are due to be delivered to TUI's airlines by 2023 as the company revamps its fleet.
It will receive a total of nine aircraft, all Max 8s, this year. They will be distributed among its Belgian, Swedish, UK and Dutch operations. Germany's TUIfly operation will take its first in early 2019.
