Singapore Airlines’ Flight SQ 23 is famously the longest nonstop commercial flight in the world. It travels from New York JFK to Singapore, covering 9,537 miles and taking 18 hours and 40 minutes to complete.

Note that scheduled flight times vary with the direction flown, and actual flight times are often less. Here are the five longest nonstop flights from the United States after SQ-23.
