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

In 2026, ultra-long-haul flights will span thousands of kilometers without a fuel stop. The longest scheduled non-stop passenger routes now crisscross the Pacific, Indian Ocean, and other major air corridors, often keeping passengers airborne for nearly 20 hours.

New York to Singapore, operated by Singapore Airlines, is the longest non-stop flight at approximately 15,330 km. It typically takes around 19 hours and 15 minutes. The Newark to Singapore service, also by Singapore Airlines, is just a few kilometers shorter and takes 18-19 hours.

Qantas Airways runs a direct Perth to London route, covering about 14,500 km and lasting between 17 hours 20 minutes and 18 hours. Another American Airlines- Qantas Airways service connects Dallas/Fort Worth to Melbourne, with a distance of about 14,470 km and a flight time of around 17 hours 40 minutes.

These ultra-long-haul flights rely on aircraft built for extended operations, featuring larger fuel capacity, efficient engines, and configurations suited for long journeys. Airlines must also consider factors like crew rest, fuel needs, alternate airports, and weather conditions when planning these flights.
