Which Is the Longest Non-Stop Commercial Flight?
Quick Answer
Singapore Airlines' service between Singapore and New York JFK is the longest regular non-stop flight, covering about 15,300 kilometres in roughly 18 to 19 hours.
The Full Story
Singapore Airlines flights SQ23 and SQ24 connect New York's JFK airport and Singapore Changi across a great-circle distance of about 15,349 kilometres. Depending on winds, the journey takes around 18 to 19 hours. The route uses an Airbus A350-900ULR, an ultra-long-range version with extra fuel capacity. Singapore Airlines had flown an even longer Newark route in the 2000s before cancelling it because of high fuel costs. Australian airline Qantas plans 'Project Sunrise' non-stop flights from Sydney to London and New York using specially modified A350-1000 aircraft.
