How to change a Southwest Airlines flight
As a low-cost carrier, Southwest Airlines typically charges a change or cancellation fee that gets smaller the earlier you act — and is often waived when you change far enough in advance. Fares are usually non-refundable unless you add a flexibility option. Southwest charges no change or cancellation fees at all; non-refundable fares are kept as Travel Funds and refundable fares go back to your original payment.
Fastest way to change: Call +1 (855) 302-0422 with your confirmation code.
Our agents will check your fare rules, find the best new flight, and rebook you in minutes — 24/7.
Cancelling a Southwest Airlines flight & getting a refund
Under U.S. Department of Transportation rules, you can cancel within 24 hours of booking for a full refund if you booked at least 7 days before departure. If Southwest Airlines cancels your flight or makes a major schedule change, you're entitled to a cash refund — not just a credit. Voluntary cancellations of non-refundable fares are typically returned as credit, minus any applicable fee.
For the full breakdown, see our guides on cancelling a flight and getting a refund and the 24-hour cancellation rule — or just call and we'll handle it.
Southwest Airlines seat selection & upgrades
Southwest Airlines charges separately for seat selection, including bigger up-front seats. There's no traditional first class, but you can buy extra legroom, priority boarding and carry-on/checked bags.
