TUI Airways officially retired its last Boeing 757-200 in October 2021. The final commercial flight for the type was operated by aircraft G-OOBB on October 3, 2021, traveling from Paphos to Birmingham. This retirement marked the end of an era for the airline, which once operated a peak fleet of 31 units of the midsized jet. In 2026, TUI's narrowbody operations are centered on the more fuel-efficient Boeing 737 MAX 8 and 737-800 models. The retirement was part of a broader fleet modernization strategy to reduce carbon emissions and operational costs, transitioning away from the iconic "pencil jet" in favor of newer technology. While the 757 remains a favorite among aviation enthusiasts for its high performance, TUI, like many other European leisure carriers, has fully transitioned its short-to-medium haul routes to the 737 family, while using the 787 Dreamliner for its long-haul network.
