TheSouthwest Airlines boarding process is unique and straightforward, designed to keep things efficient and fair. Depending on when they check in, passengers are given a number (1–60) and a boarding group (A, B, or C) in place of assigned seats. Your boarding position improves the earlier you check in. A1 boards first, then A2, and so on. Groups board in numerical sequence. Once on the aircraft, travelers are free to select any seat that is available. Passengers with impairments and families with small children can board early. For a charge, Southwest also provides EarlyBird Check-In, which enhances your boarding position. This open-seating approach promotes a quick and easy boarding process.
