In the U.S., the airlines JetBlue and Southwest consistently offer the most legroom with an average of around 32 inches per seat, although you can find a few JetBlue planes with 33 inches of legroom. Alaska and Hawaiian seats typically have 31 or 32 inches of legroom, too.

In 2026, the airlines offering the most room in standard Economy (known as "seat pitch") are consistently Japan Airlines (JAL), All Nippon Airways (ANA), and Emirates. These carriers set the global standard with an average seat pitch of 34 inches on their long-haul aircraft, which is significantly more generous than the 30–31 inches found on many major U.S. and European legacy carriers. JAL is particularly noted for its "Sky Wider" economy seats, which use a slim seatback design to provide even more knee room than the numbers suggest. In the United States, JetBlue remains the leader for domestic comfort, offering an average of 32.3 inches of legroom in its standard "core" seats, which is the most of any major U.S. airline. On the other end of the spectrum, ultra-low-cost carriers like Spirit or Ryanair often have as little as 28 inches. For travelers who prioritize physical comfort without paying for a Premium Economy upgrade, booking with these top international carriers provides a noticeably more spacious and less "cramped" experience during long-range flights across the Pacific or to the Middle East.
