Australian carrier Qantas has completed a test of the longest non-stop commercial passenger flight as part of research on how the journey could affect pilots, crew and passengers.
The Boeing 787-9 with 49 people on board took 19 hours and 16 minutes to fly from New York to Sydney, a 16,200-km (10,066-mile) route.
Next month, the company plans to test a non-stop flight from London to Sydney.
Qantas expects to decide on whether to start the routes by the end of 2019.
