The world’s longest nonstop flights, updated

Editor's note: This is a recurring post, regularly updated with new information.

Ultra-long-haul flights are back in the air after a brief pause during the pandemic. These flights, which can take as long as 19 hours, connect some of the world's biggest cities without a stop in an intermediate hub.

Singapore Airlines has long been known for operating some of the world's longest flights. The carrier connects Singapore with two New York City-area airports on a daily basis, and both routes top the list of the world's longest flights.

Other carriers have recently launched new and interesting ultra-long-haul routes, including Air New Zealand's new flight from New York to Auckland, New Zealand, which took off last September.

While Air New Zealand was a newcomer to the top 10 list last year, Qantas is giving the airline a run for its money by launching its own route from New York to Auckland this week. At 8,829 miles, it will tie with Air New Zealand's service as the world's fifth-longest flight.

Qantas is no stranger to ultra-long-haul flying. (It's just too bad its existing wide-body fleet doesn't yet feature Wi-Fi.) The airline also holds the title for the world's third, fourth and 10th longest flights; in a few years, it might also hold the record for the longest.

That's because Qantas' "Project Sunrise" routes will include nonstop service from Sydney to both London (10,573 miles) and New York (9,950 miles). Although the airline ran proof-of-concept tests in 2019, those flights are not expected to launch until at least 2025, so they don't make the list yet.

Here are the top 10 longest routes operating in June 2023 measured by statute miles as calculated by travel data firm OAG. (Note: For consistency, all mileage calculations come courtesy of OAG. Other data providers may show slightly different mileage calculations depending on their methodology.) Duration of flight data comes from Cirium, an aviation data service.

We've listed the flight that typically has the longest scheduled flying time, normally the one that flies in the direction of typical head winds. Given geopolitical tensions associated with Russia's invasion of Ukraine, some actual flight times might be considerably longer than what is listed as airlines avoid Russian airspace. Other routes that might not normally make the cut — such as Cathay Pacific's New York-to-Hong Kong route — are flying longer-than-normal flight paths as they also seek to avoid Russian airspace.

Additionally, keep in mind that the listed times are those that are blocked in airline schedules; during actual travel, flights can be shorter or longer depending on the winds.

Scroll down to see the full list, and we'll update it regularly as new routes begin and suspended ones resume.
