If you purchased early-bird check-in as an added extra, you can expect to be checked in automatically and receive a reserved boarding position 36 hours prior to your flight’s departure. You will be able to print your boarding pass 24 hours before your flight or collect your pass from the aforementioned Southwest Airlines locations.

Where can I buy a Southwest Airlines gift certificate?

Give your loved ones the gift of a well-deserved trip and purchase a gift card from the Southwest Airlines gift card page.

What is the Southwestern Airlines refund policy?
