Travel is stressful, and sitting in a cramped seat for six hours doesn't help. Routehappy does some important research to figure out which airlines have the most leg room in their standard coach seats.


Their findings, embedded above in table form from Skift.com, show that Southwest has the most flights per day with free "roomier" seats (that is, seats with 32" or more of room)k, though that is only 31% of their flights. Conversely, if you fly JetBlue or Virgin America, you have a 100% chance of being on a flight with extra leg room—even though they have fewer "extra leg room" flights per day than Southwest or Alaska.


If you're willing to pay a bit more for extra leg room, they've got info on that too. Delta has the most flights, but only 67% of its flights have those seats available, while 100% of JetBlue, Frontier, Spirit, and Virgin America have spacious seats available for a fee.
