Check in for your Southwest flight to confirm your trip and get your boarding pass. On a Basic fare your Standard seat is assigned at check-in; on other fares you already chose your seat at booking. Your numbered boarding group (Groups 1–8) is set by your fare and seat.
Check in ahead of your flight to confirm your trip and receive your boarding pass (mobile or printed). If you booked a Basic fare, your Standard seat is assigned at check-in; every other fare already has a seat chosen at booking.
As of January 27, 2026, Southwest uses assigned seating. You choose a specific seat at booking (or at check-in on Basic fares) from three seat types: Extra Legroom, Preferred, and Standard. Boarding uses numbered Groups 1–8; the earlier your group, the sooner you board. Priority Boarding can be purchased for $10–$75 per segment to board ahead of your fare's default group.
| Boarding group | Who boards |
|---|---|
| Groups 1–2 | Choice Extra fares and Extra Legroom seat holders |
| Groups 3–5 | Choice Preferred fares, Preferred seat holders, and A-List Members (board no later than Group 5) |
| Groups 6–8 | Choice fares and Standard seat holders |
| Last | Basic fares |
On Basic, Choice, and Choice Preferred fares, checked bags cost $45 for the first and $55 for the second, each way on the U.S. mainland (rates effective April 9, 2026). A carry-on plus one personal item is always FREE.
WiFi is FREE for Rapid Rewards Members on every flight, through a partnership with T-Mobile — Members log in with their Rapid Rewards credentials. Travelers who aren't Members can purchase access.
