My achilles heel when I travel is it's at least 2,500 miles to the nearest continent from Honolulu, Hawaii. At its shortest the flight to the west coast of the United States is about five hours. That duration is considered a mere fraction of the time to fly some of the longest flights in the world ranked by hours. Now it would be amazing if anyone on these flights doesn't at least get up once to go to the restroom unless they're unconscious for the entire duration or seeking deep vein thrombosis as a goal.

Probably the best thing about these very long-haul flights is there's no layover and it helps to earn elite level on each airline that much easier.

The ranking is determined by U.S. News & World Report. Notice that the miles between destinations does not necessarily determine the longest flights.

It should be noted that Singapore Airlines operates a business-class only airplane for 100 passengers on this Los Angeles to Singapore route. The reason this flight is shorter than the Newark to Singapore flight is the route taken by the airline's jets. The Newark flight path across the North Pole subjects the aircraft to less wind resistance, allowing it travel faster than the flight from Los Angeles, which crosses the Pacific Ocean.
