As of early 2026, the record for the longest commercial flight is held by Singapore Airlines Flight SQ23/SQ24, connecting Singapore (SIN) to New York (JFK), covering approximately 9,537 miles (15,349 km) with a flight time of roughly 18 hours and 45 minutes. However, 2026 is a pivotal year for ultra-long-haul travel as Qantas prepares to launch its "Project Sunrise" flights. These flights are designed to connect Sydney (SYD) directly to London (LHR) and New York (JFK) non-stop using specially modified Airbus A350-1000ULR aircraft. These routes will span over 10,500 miles and can last between 19 and 22 hours. While some specialized charter or military flights have gone longer, these represent the current and upcoming boundaries of scheduled passenger aviation, featuring dedicated "wellness zones" to help passengers survive nearly an entire day in the air.
