Ultra-long-haul (also known as "ultra-long-range operations" ) refers to the duration of a flight (flight time) being "ultra long." IATA, ICAO, and IFALPA jointly define any flight scheduled to last over 16 hours as "Ultra Long".[1][2][3][4]
These flights usually follow a great circle route, often passing over a polar region. In some cases, non-stop ultra-long-haul routes could be less preferable to stopover flights as passengers on ultra-long-haul nonstop flights must sit in the aircraft for those long hours.[5] A low-oil-price environment favors the establishment and operation of ultra-long-haul flights.
Since 9 November 2020, Singapore Airlines Flights 23 and 24 has been the world's longest active commercial flight, between Singapore and New York JFK airport, covering 15,349 km (9,537 mi; 8,288 nmi) in around 18 hours and 40 minutes, operated by an Airbus A350-900ULR.[6]
