Southwest is offering free flights for a limited time

Southwest fliers need to act fast.

Southwest Airlines has announced the return of its highly-coveted Companion Pass promotion — but the time to purchase is ticking.

The Companion Pass is essentially buy-one-get-one free, allowing Rapid Rewards members to designate one person to fly with them for free every time the member purchases or redeems points for a flight.

“We love offering this Companion Pass promotion because it allows our Members to experience one of the many benefits of our award-winning Rapid Rewards program,” Jennifer Bridie, Vice President of Marketing at Southwest Airlines, said in a statement.

To get the promotion, travelers must register for the pass and then purchase one round trip or two one-way flights. The purchase must be made by the end of the day on Thursday, Sept. 5.

The reward member must also travel with Southwest by Nov. 20 and designate a companion to fly free with the member between Jan. 6, 2025, and March 6, 2025.

“Earlier this year, we launched Cash + Points, giving our Customers extra flexibility to make their points go further. And now, for the first time, Members can use their Rapid Rewards points, a combination of cash and points, or other eligible forms of payment to book qualifying flights that count toward this Companion Pass promotion,” Bridie said.

The promotion is only available to Rapids Rewards members, and registrants will receive an email letting them know they’ve qualified for the promotion.

Once you receive the pass, you can change the friend or family member you’re designating as your companion up to three times.

Recently, Southwest announced that it will start assigning seats to flyers, getting rid of its pick-any-seat flying policy.
