Longest Flights in the World (2026 Guide)
Modern aviation has made it possible to travel between distant continents without stopping. Today, airlines operate ultra-long-haul flights that can last more than 15 hours and cover tens of thousands of kilometers.
These flights connect major global cities across continents, allowing travelers to reach their destination faster without layovers. In this guide, we explore the longest flights in the world, how long they take, and why airlines operate these routes.
