Qantas A380 flying world's longest route

The world's largest passenger aircraft- Airbus A380 superjumbo- is flying the world's longest air route from Sydney to Dallas.

According to Stuff.co.nz, the Qantas Sydney-Dallas route became the longest non-stop flight in the world late last year after Singapore Airlines ended its non-stop flights from Singapore to New York, a 19-hour slog that covered 16,700 kilometres on a four-engine Airbus A340-500.

The A380 superjumbo will take a little more than 15 hours to cover the Sydney-Dallas route at 13,800 kilometres.

Qantas CEO Alan Joyce said that the A380 would increase seats on the route by more than 10 per cent each week, adding that it will also ensure greater fuel efficiency and the range to operate the return service direct back to Sydney.
