Companion Pass® holders who have a Companion already booked and are eligible to use the same-day change benefit can take the following steps:

On Southwest.com or in the mobile app:

• The Companion Pass holder must cancel their Companion’s reservation (do not cancel your own flight).
• The Companion Pass holder can change their flight through the same-day change benefit.
• The Companion Pass holder can add their Companion to the new flight through their Rapid Rewards account.

At the airport:

All eligible Customers can make these changes at the airport with a Southwest Agent at the ticket counter or departure gate or by calling 1-800-I-FLY-SWA.

Keep in mind that a Companion must travel with the Companion Pass holder. If the Companion and Companion Pass holder choose not to travel together, the Companion must purchase a ticket at the applicable fare in order to travel.
