How does seating work on United Airlines?

With Basic Economy, you'll automatically be assigned a seat before boarding, and you won't be able to change your seat once it's assigned. Advance seat assignments may be available for purchase during booking and up until check-in opens.



Seating on United Airlines in 2026 is primarily determined by your fare class and elite status. For standard Economy tickets, you can select your seat at the time of booking or through the "My Trips" section later. Economy Plus offers up to 6 inches of extra legroom and is available for purchase or complimentary for Premier members. If you book a Basic Economy ticket, you generally cannot select a seat for free; one will be automatically assigned at check-in, though you may pay a fee to choose one in advance. United also has a "Family Seating" policy where up to two children under 12 can sit next to an adult in the party for free, even on Basic Economy fares. For premium cabins (United First or Polaris), seats are wider, fully lie-flat on international routes, and include priority boarding.
