TUI Airways (BY, London Luton) operated its last commercial B757 flight on October 3, 2021, and will henceforth focus on a new-generation fleet of B737 MAX and B787s.

G-OOBB (msn 32447), a 20.8-year-old jet owned by GECAS and operated by TUI Airways since 2010, flew for the last time from Paphos to Birmingham, GB as BY7723, Flightradar24 ADS-B data shows. G-OOBP (msn 30394) operated its last flight, from Irakleion to London Gatwick, earlier that same day, while G-OOBN (msn 29379) was retired on September 30, 2021.

All three units were acquired in mid-June 2021 by Blackrock Investment Management for conversion into freighters.

The ch-aviation fleets history module shows that TUI Airways' fleet of B757-200s peaked at 31 units in 2008 (when the airline was known as Thomson Airways). Since then, it has been gradually retiring the type in favour of B737-800s, and more recently, B737-8s and B787s. The airline currently operates fifteen B737-8s, thirty-two -800s, four B767-300ERs, eight B787-8s, and five B787-9s.

UK's TUI Airways was TUI Group's last remaining B757 operator. TUI fly Nordic (then known as Britannia Airways AB) operated the type through 2011.
