15,000 km and 19 hours later: Check out the world’s longest non-stop passenger flights

The world's longest non-stop passenger flights have become a reality, covering distances of over 14,000 kilometers without requiring a fuel stop. In 2026, some of the longest scheduled non-stop passenger routes will span across the Pacific, Indian Ocean, and other major air corridors, with some flights keeping passengers airborne for nearly 20 hours. Here are some of the longest currently operating routes, ranked by great-circle distance.

New York to Singapore, operated by Singapore Airlines, has the distinction of being the longest non-stop passenger flight. This route spans approximately 15,330 kilometers and can take close to 19 hours and 15 minutes. Another route operated by Singapore Airlines connects Newark Liberty International Airport to Singapore. This route is only a few kilometers shorter than the JFK route but still ranks among one of the world's longest scheduled non-stop flights. It covers roughly the same distance and can take around 18-19 hours.

Qantas Airways also operates some of the longest non-stop passenger routes. One of these is the direct service between Perth in Western Australia and London. This route covers approximately 14,500 kilometers and takes around 17 hours and 20 minutes to 18 hours. Another Qantas route, connecting Dallas/Fort Worth in the United States to Melbourne, Australia, is also among the world's longest non-stop passenger flights.

At approximately 14,470 kilometers, it has a scheduled flying time of around 17 hours and 40 minutes. These ultra-long-haul services are made possible by specialized aircraft with larger fuel capacity, efficient engines, and configurations tailored for extended operations. Airlines must also take into account crew rest, fuel requirements, alternate airports, and weather conditions when planning these lengthy flights.
