The Southwest Airlines boarding process is simple and efficient but different from most other airlines. Instead of assigned seats, passengers receive a boarding group (A, B, or C) and a position number (1–6 when they check in. Groups board in order, starting with A, then B, and finally C. Within each group, passengers line up according to their number and choose any available seat once onboard. Visit: https://www.airlinesticketoffi....ce.com/blog/southwes
