Alaska Airlines seats are generally considered average to slightly above average in size compared to other major U.S. domestic carriers. In the Main Cabin (Economy), the "pitch" (the distance from one seat back to the next) is typically 31 to 32 inches, which is on par with Delta and American and better than the 28-30 inches often found on "budget" airlines like Spirit or Frontier. The seat width is a standard 17.5 inches. However, Alaska has recently upgraded many of its Boeing 737 aircraft with "Slimline" seats; while these seats feel "harder" to some, the thinner design actually provides slightly more knee room for taller passengers. For those seeking more space, Premium Class offers a significant upgrade with 35 to 36 inches of pitch. In 2026, the airline's new 787 Dreamliner fleet has also introduced much larger "enclosed suites" in First Class for international routes, but for the standard traveler on a domestic hop, Alaska's seats provide a reliable, if unexceptional, amount of space that is widely regarded as comfortable for flights under five hours.
