Unlike other airlines, Southwest Airlines has a different boarding procedure. Passengers are given a number between 1 and 60 and a boarding group (A, B, or C) in place of assigned seats. The order in which you board the aircraft is determined by this group and number. Your boarding position improves the earlier you check in. Once on board, you can select any available seat because Southwest offers open seating. Visit: https://www.airlinesticketoffi....ce.com/blog/southwes
