If you have traveled between the Americas to Europe or Asia, you’re probably familiar with some of the longest nonstop flights available. These commercial routes across the Pacific and Atlantic Oceans can easily take over 10 hours to complete, but what’s the longest flight in the world? Coming in at No. 1 is the Singapore Airlines route between New York’s JFK Airport and Singapore’s Changi Airport. It has a great circle distance of just over 9,500 miles, with the direct flight lasting an average of 18 hours and 40 minutes from takeoff to landing. At exactly half the circumference of the earth, the longest flight route possible on the planet would be 12,430 miles. Two major cities that nearly align with this great circle distance are Shanghai, China, and Buenos Aires, Argentina, but no available aircraft can travel such a route on a direct flight. The world's longest-range commercial jet, the Airbus A350-900, would burn up a full tank of fuel after 11,000 miles.
