Southwest Airlines uses a unique boarding system with three main groups: A, B, and C. Within each group, passengers are assigned a number from 1 to 60, determining boarding order. Business Select fares and upgraded boarding typically provide A1–A15 positions. EarlyBird Check-In improves the chance of boarding earlier, while family boarding occurs between groups A and B. Because seating is open, earlier boarding ensures better seat selection. Understanding this system is key for travelers wanting the best seats.
