How to cancel Southwest Airlines

What its contract says about leaving.

We read the Southwest Airlines terms on April 28, 2026. The company may have changed them since, and your contract may be different.

Notice and dates for leaving

24-hour free cancellation window
Within 24 hours of booking, provided travel is at least 7 days away
Wanna Get Away cancellation deadline
At least 10 minutes before scheduled departure to preserve fare as Travel Funds

What the contract says about leaving

  • Wanna Get Away forfeiture if not cancelled in timeIf you do not cancel a Wanna Get Away or Wanna Get Away Plus ticket at least 10 minutes before departure, the entire fare value is forfeited and is not preserved as Travel Funds.
  • Travel Funds and credit expiration nuancesAlthough most Travel Funds and Transferable Flight Credit no longer expire, fare-difference rules still apply on rebooking, and any award/voucher booked using Rapid Rewards points has its own redemption terms.

This page does not explain how Southwest Airlines handles canceling (by phone, on its website or with a form). For that, see the company's own page.
