Turkish Airlines is one of the world's largest carriers by destinations — 340+ airports in 129 countries — making it the most important airline for long-haul Brompton travel connecting Europe with Asia, Africa and the Americas via Istanbul. Their bike policy has a generous quirk: on flights arriving into select Turkish tourist destinations including Antalya, Adana and Kayseri until December 2026, one bicycle travels completely free. On all other routes the standard sports equipment fee applies.
