Australian airline Qantas recently had a successful run with the longest non-stop commercial flight.
The flight originated in New York and terminated in Sydney, Australia after spending 19 hours and 16 minutes in the air. They took the opportunity to run a series of tests to assess the effects of ultra-long haul flights on crew fatigue and passenger jetlag.
A total of 49 were on board to include four pilots on the Boeing 787 Streamliner that completed the feat of not stopping over the 16200 km route. There are now plans to tests non stop flights between London and Sydney next month.
Qantas expects to decide whether the route is plausible by year-end and if affirmative, services could start by 2022. So far, they have used maximum fuel and limited cargo to test the flight but things are expected to increase going into more tests.
