Route-Happy found that Southwest Airlines has the most flights with roomier seats followed by Alaska Airlines, Jet Blue, U.S. Airways and Virgin America.
That extra leg room means you can sit with your laptop open even with the seat in front of you reclined.
Of the flights that have roomier economy seats, you can get them for free on 13 percent of all domestic flights. To snag one of the rest of the seats, you'll either have to be a frequent flier or pay extra.
