The Southwest Airlines Boarding Process is unique and centers around open seating. Passengers are assigned boarding groups (A, B, or C) and a number within that group based on check-in time or upgrades. There are no assigned seats—travelers choose their seats once onboard. EarlyBird Check-In and Business Select fares help improve boarding position. Visit: https://www.airlinesticketoffi....ce.com/blog/southwes
