United Airlines allows passengers to select seats during the booking process or after purchasing a ticket. Here's some information about United Airlines' seat selection policy:

At Booking: When you book your flight on United Airlines, you can choose your seats during the booking process. You'll be given the option to select your preferred seat, whether it's an aisle seat, a window seat, or a seat with extra legroom for an additional fee.

After Booking: If you don't select your seat at the time of booking, you can still choose or change your seat later. You can do this through the United Airlines website or mobile app. There may be additional fees for certain seat selections, such as Economy Plus or premium seats with more legroom.

Preferred Seats: United offers Preferred Seats for an additional fee. These seats are located in the front of the Economy cabin and provide passengers with early boarding and more legroom.
MileagePlus Premier members may receive complimentary access to these seats.

Premium Cabin: Passengers traveling in premium cabins (First Class and Business Class) typically have access to more comfortable and spacious seats, which can be selected during booking or check-in.

Basic Economy: If you purchase a Basic Economy ticket, your seat will be assigned at check-in, and you won't have the option to choose your seat in advance. However, you can still purchase seat assignments for an additional fee if desired.

Families and Groups: United Airlines tries to seat families and groups together whenever possible. If you're traveling with children or as part of a group, you can request to be seated together during the booking process or at the airport.

Special Needs: If you have special seating needs due to a disability or medical condition, United Airlines provides assistance to ensure you have a suitable seat. You can contact the airline's Special Needs team in advance to arrange for accommodations.
