What you can manage on a Southwest booking
The common tasks. What's possible on a given ticket depends on its fare rules.
On southwest.com or the Southwest app you'll need your confirmation number (a six-character code) and the passenger name. Keep it handy — we'll ask for it too.
Under the 2026 model you can add checked bags and select a seat after booking, often more cheaply than at the airport. Adding them in advance is the smart move.
Minor corrections like a spelling fix are frequently possible; bigger changes may need a reissue and get harder close to departure, so don't wait.
Adding your Rapid Rewards number means you earn points and any A-List benefits apply. Easy to miss, easy to add.
Date changes and cancellations follow your fare rules — Southwest generally charges no change fee on most fares. See our change & cancellation guide, or just call and we'll handle it.
What a booking allows depends entirely on its fare and route. Tell us your confirmation number and what you want to do, and we'll tell you what's possible and take care of it — Southwest's own tools at southwest.com are always free.
