At nearly 19 hours, Singapore Airlines Singapore-New York route eclipses Qantas’s 17-hour London-Perth service, launched earlier this year.
Singapore Airlines axed its Newark and Los Angeles routes in 2013 citing high fuel prices, Reuters reports.
The routes were operated by quad-engine Airbus A340 aircraft and the subsequent fuel consumption made the services economically unviable.
However, its seven new twin-engine ultra-long range Airbus A350s will make the route viable again.
Singapore-Newark, at around 9,500 miles, will pip Qatar Airways’ Doha-Auckland route.
