The Southwest Airlines Boarding Process is unique due to its open-seating policy, meaning passengers choose their seats upon entering the plane. Travelers are assigned to boarding groups A, B, or C, with numbers ranging from 1 to 60. The order is based on check-in time, ticket type, and loyalty status. EarlyBird Check-In and Business Select fares can secure better boarding positions. Families with young children and passengers needing assistance may board early.
