Longest flight goes to Aussie airline

Singapore Airlines is cancelling the world's longest commercial flight, giving the title to the Qantas flight between Sydney and Dallas.

Singapore Airlines announced on Wednesday it would end its nonstop flight between Singapore and Newark, a distance of about 15000 kilometres.

A slightly shorter route between Singapore and Los Angeles will also end.

The flight from Newark, outside New York, to Singapore takes about 18 hours. The trip from Los Angeles is shorter but takes 18 hours and 30 minutes.

Headwinds over the Pacific Ocean slow the Los Angeles flight. The Newark flight goes over the North Pole and can fly faster.

The Newark flight is the longest-distance flight in the world and the Los Angeles one holds the record for duration.

The flights started in 2004.
