Southwest Airlines just launched a new promotion to help you earn a Companion Pass, but you must act fast. The newest offer lets members earn a temporary Companion Pass after just one eligible roundtrip (or two one-way flights) booked by February 20, 2025 and flown by March 31, 2025.
Here are the details of this flash Southwest Companion Pass promotion.
Earn a Promotional Companion Pass In One Round-Trip
A few times a year, Southwest offers travelers the chance to earn a temporary Southwest Companion Pass. However, these promotions always have a short booking window and the Companion Pass you earn is only valid for a short period.
To take advantage of this promotion, you'll need to book a round-trip (or two one-ways) by February 20, 2025 for travel before March 31, 2025. Before booking your flights, you must register for this promotion. Then, after completing the one roundtrip (or two one-way flights), you will receive a temporary Companion Pass valid from August 7 through October 8, 2025.
If that seems short, you're not wrong. This temporary Companion Pass will only be valid for two months this fall. But there's another way to earn a Companion Pass for longer (that we'll detail below).

Terms and conditions
- Members must register for this promotion before booking the qualifying flights.
- Book a round-trip flight or two one-way flights before February 20, 2025 for flights between now and March 31, 2025.
- Receive a Companion Pass valid between August 7 and October 8, 2025.
- Designate your companion after receiving the pass. You can change your Southwest Companion Pass companion up to three times.
Our Take
Southwest has offered a similar promotional Companion Pass several times over the past few years. This time, Southwest is offering the chance to earn a Companion Pass that's only valid for two months during slower fall travel. On the positive side, Southwest isn't blacking out Companion Pass travel around any fall holidays.
If you already have a flight booked during the promotional period, remember that Southwest has no cancellation fees. Even though the offer states it's only valid on new bookings, you might be able to cancel your existing reservation, register for this promotion, and then rebook your flights.
