Singapore Airlines has long been one of the leading ultra-long-haul airlines in the world, and its Airbus A350 fleet has become pivotal to maintaining this reputation. The airline is the operator of the world’s longest scheduled nonstop commercial service — a 19-hour-plus flight between Singapore Changi Airport (SIN) and New York JFK Airport (JFK) that it has flown since 2020 — and operates several more extremely long routes out of its SIN hub.
