The world's longest commercial flight - Singapore to Newark, New Jersey - is being cancelled.
Singapore Airlines announced this week that it will end its nonstop flight between Singapore and Newark, a distance of about 15,000 kilometres.
A slightly shorter route between Singapore and Los Angeles will also end. The two routes were flown on gas-guzzling Airbus A340-500s.
The airline found the only way to make the routes profitable was by configuring the plane with 98 business class seats that sell for about $8,000 roundtrip. Other airlines operate the same plane with about 250 seats in first, business and economy classes.
The flight from Newark to Singapore takes about 18 hours. The trip from Los Angeles is about 2,400 km shorter but takes 18 hours and 30 minutes.
Headwinds over the Pacific Ocean slow the Los Angeles flight while 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.
The new titles for longest flights will go to a Qantas route between Sydney and Dallas - which at about 13,500 km is the longest route - and a Delta flight between Johannesburg and Atlanta, which at 17 hours will hold the title of longest duration.
Singapore Airlines is selling its five A340-500s back to Airbus as part of a deal announced this week. Singapore is ordering five more Airbus A380s and another 20 A350s. The planes have a list price of $7.5 billion but airlines often negotiate steep discounts for large orders. Deliveries are due to begin in 2017.
Singapore currently operates 19 A380-800 superjumbos. It already had firm orders in place for 20 A350s, for delivery starting in 2015.
