Southwest offering 2-month Companion Pass — all you have to do is book a round trip!
Southwest Airlines is offering travelers a chance to easily score its coveted Companion Pass. For a limited time, you can earn the right to fly with a plus-one at no added cost — simply by booking one round-trip flight.
The offer, which Rapid Rewards members must register for online before booking their next trip, grants a two-month Companion Pass to travelers who purchase either a round-trip flight or two one-way flights by 11:59 p.m. CDT on Aug. 28, Southwest confirmed to TPG.
Travelers then need to fly by Nov. 15.
While many flights qualify for this offer — including Rapid Rewards redemptions and Cash + Points bookings — the carrier's new Basic fares are not eligible.
Passengers who earn one of these promotional Companion Passes can then use it from Jan. 6 to March 6, 2026, allowing them to bring a friend or loved one with them on flights practically for free (not including the cost of taxes and fees, starting at $5.60 one-way).
If you're thinking of booking a handful of winter getaways (such as a flight to Southwest's newest Caribbean destination), this offer can be a way to save hundreds of dollars.
What to know about Southwest's promotional Companion Pass
Pass holders must select a designated companion, but can change that companion up to three times during the two-month period.
"We love offering Companion Pass because it allows Customers — new or long-time Rapid Rewards Members — access to the many benefits of our award-winning loyalty program," a Southwest spokesperson told TPG.
Beyond the return of the popular promotional offer, travelers can earn a yearly Companion Pass by either flying 100 qualifying one-way flights or earning 135,000 qualifying points in a calendar year. These points can be earned through a variety of methods, including using a qualifying credit card.
Bottom line
The promotion comes as Southwest revamps how it does business.
Last month, the airline started selling assigned seats for flights departing on or after Jan. 27, 2026, as it does away with its long-standing open-seating policy.
Last week, the carrier formalized a new partnership with Taiwan-based China Airlines, and said it would soon launch Rapid Rewards redemptions on international partners.
