16-Hour Flights: United Launches New Ultra-Long Nonstop Route In 2 Weeks [Map]

United Airlines is set to launch a new ultra-long non-stop route between Washington Dulles International Airport (IAD) and Tokyo Haneda Airport (HND), marking their first such service. The airline anticipates offering this direct flight for approximately 16 hours, significantly reducing travel time compared to connecting itineraries. This ambitious undertaking will commence within two weeks, according to United’s announcement. Previously, United operated only one-stop options to Japan; however, they have not previously offered nonstop flights. Demand for increased connectivity between North America and Asia continues to drive airlines to explore longer routes.
