Singapore Airlines Flights 23 and 24 (SQ23/SIA23 and SQ24/SIA24, respectively) are the longest regularly scheduled non-stop flights in the world, operated by Singapore Airlines between Singapore Changi Airport and New York–JFK.[1] The route launched on 9 November 2020.[2]

The route has a great circle distance of 15,349 kilometres (9,537 mi; 8,288 nmi).[3] However, SQ24 to New York is typically flown a ground distance of around 17,250 km (10,720 mi; 9,310 nmi)[4] over the Pacific Ocean where jet stream winds can assist; while SQ23 back to Singapore sometimes opts, instead of the westward polar route, to fly a ground distance of 16,500 km (10,300 mi; 8,900 nmi)[5] eastward, across the Atlantic Ocean, when favorable jet stream winds assist to save both flying time and fuel.

The flights originally used an Airbus A350-900.[6] On January 16, 2021, the route was changed to operate using an Airbus A350-900ULR.[7][8]
