This is one of the easiest ways to earn Southwest’s most valuable perk. Book a single roundtrip before February 5, 2026, and you’ll unlock a promotional Companion Pass valid for nearly two months this fall—essentially turning every flight into a two-for-one deal.
How This Southwest Companion Pass Promo Works
The mechanics are straightforward, but the timeline is tight. You have until 11:59 p.m. CST on Thursday, February 5 to book a qualifying flight.
Here’s what you need to do:
- Register for the promotion using your Rapid Rewards number (you must register before booking)
- Purchase one roundtrip or two one-way tickets between February 2 and February 5, 2026
- Complete your travel by March 31, 2026
The good news is that Southwest gives you plenty of flexibility in how you book. All fare classes qualify, including the airline’s new Basic option. You can pay with cash, Rapid Rewards points, or Cash + Points—it doesn’t matter as long as you book through Southwest’s website or mobile app.
Your reward for booking is a promotional Companion Pass valid for travel between August 10 and October 7, 2026. That’s roughly two months of companion travel for the cost of one flight.
What Is Southwest Companion Pass?
If you’re not familiar with Companion Pass, here’s why it’s considered one of the best deals in travel. When you have Companion Pass, a designated companion can fly with you on any Southwest flight for just the cost of taxes and fees, which start at $5.60 per flight.
This works on unlimited flights and applies whether you’re paying cash or redeeming points. The only requirement is that there’s an open seat on the plane—which, on Southwest, there almost always is.
Here’s the kicker: earning this perk normally requires 135,000 qualifying points or 100 qualifying one-way flights within a calendar year. That’s a substantial commitment. This promotion lets you skip past all of that with a single booking.
Think of it as a two-for-one travel pass. You pay for your ticket, your companion pays just $5.60. That kind of value is essentially unheard of elsewhere in the airline industry.
Who Should Jump on This Deal
This promotion isn’t for everyone, but if you fit the criteria, the value is exceptional.
You’re an ideal candidate if you already have travel planned between now and March 31. You’ll need to complete your flight during that window to qualify. You’re also an ideal candidate if you have flexibility in August through early October, since that’s when your promotional pass will be valid.
The two-month window is admittedly limited compared to a full Companion Pass, which lasts through the end of the following calendar year. But for a single roundtrip booking? The math works out heavily in your favor.
For frequent Southwest flyers, this is a no-brainer. You were going to fly anyway—now that flight earns you months of companion benefits.
Tips to Qualify If You Already Have Flights Booked
Here’s a strategy that opens this promotion to many more travelers. If you already have a Southwest flight booked for travel before March 31, you can cancel that booking for a travel credit and then rebook the exact same flight.
Southwest allows free cancellations on all fare classes, including Basic fares. Several people have successfully used this approach in past promotional periods to earn a Companion Pass without planning any additional travel.
One important warning: if you make any changes to your itinerary after February 5, you may no longer qualify for the promotional pass. Book your flights, lock them in, and don’t modify them.
This workaround dramatically expands who can participate. You don’t need to plan new travel—you just need to rebook travel you already had on the books.
What You Can Do With a Promotional Companion Pass
The promotional Companion Pass works exactly like the full version during its valid window. Your companion flies for just taxes and fees on every Southwest flight you take between August 10 and October 7.
Companion Designation Rules
There’s one restriction to keep in mind. You can’t bring a different companion on every trip. Instead, you designate one companion in your Rapid Rewards account, and that person is your companion for all flights.
The good news is that you can change your designated companion up to three times during the promotional period. That gives you flexibility to travel with different people across the two-month window—just not on a trip-by-trip basis.
It’s also worth noting that Southwest recently announced several new international partnerships. Partner bookings aren’t available through Southwest’s channels yet, but if that feature launches by August, your promotional Companion Pass could unlock value on international routes as well. I wouldn’t count on this, but it’s a possibility worth watching.
The Verdict
This promotion represents one of the fastest shortcuts to Southwest’s most valuable perk. A single roundtrip booking unlocks two months of companion travel, and the qualification requirements are as flexible as it gets.
If you have any Southwest travel planned before March 31—or can create some—I’d strongly consider taking advantage before the February 5 deadline. Even with all the changes Southwest has made recently, the Companion Pass remains one of the few things the airline hasn’t touched.
