There are no assigned seats, which sets Southwest Airlines apart from other airlines in its boarding process. Instead, once aboard the aircraft, customers can select any available seat from the boarding groups (A, B, or C). The greater your seat possibilities, the earlier you board. Your boarding group is determined by your check-in time, whether you purchased EarlyBird Check-In, and whether you are an A-List or Business Select member.
