The World's Longest Non-Stop Scheduled Flight Routes

The world's longest non-stop scheduled flight route (by great circle distance) is currently held by Singapore Airlines linking New York and Singapore on an 18 hour 30 minute journey. Runner up for falls to the 17hour 50 minute Qatar Airways route connecting Auckland and Doha. And rounding out the top three is the 17 hour 25 minute Qantas direct connection between London and Perth.

Note that these distances are based on the actual distances between two cities, and not necessarily the total distance flown. For instance, Air India flights from Delhi to San Francisco often fly over 14,500km to take advantage of favourable tailwinds while the direct distance between the two cities is only about 12,400km.
