Southwest Airlines is running a four-day promotional Companion Pass shortcut that can turn one qualifying round trip, or two one-ways, into a temporary companion benefit for early 2027.
If you fly Southwest with a partner or family member, the traveler job is to decide by August 6, 2026, whether to register, book, and fly under this promo before the window closes.
- Register and book by: 11:59 p.m. Central Time on August 6, 2026.
- Qualifying travel: Complete one round trip or two one-ways between August 3 and November 18, 2026.
- Benefit window: Temporary Companion Pass valid January 5 through March 3, 2027.
- Companion cost: Taxes and fees only, from about 5.60 dollars each way on qualifying flights.
- Where: Southwest Rapid Rewards account promotion detail and booking flow with your member number.
What the current promo requires
Independent reporting of the live Rapid Rewards promotion, including AwardWallet’s August 3 write-up, states that members must register for the promotion before booking, then book one qualifying round trip or two qualifying one-way Southwest flights by 11:59 p.m. Central Time on August 6, 2026. Qualifying travel must then be completed between August 3 and November 18, 2026.
Members who finish those steps earn a temporary Companion Pass valid for travel from January 5 through March 3, 2027. During that period, one designated companion can fly with the member on qualifying Southwest flights for taxes and fees only, starting at about 5.60 dollars each way, subject to capacity when the companion seat is added.
Southwest surfaces the offer inside the logged-in Rapid Rewards experience on the official promotion detail page for this campaign. Registration must happen before booking and before travel begins. Your Rapid Rewards number must be on the qualifying booking. For general program rules outside this promo, Southwest also maintains its public Rapid Rewards overview.
This is not the full calendar-year Companion Pass that normally requires 100 qualifying one-ways or 135,000 Companion Pass qualifying points. It is a short promotional pass with a fixed early-2027 travel window.
What counts, and what does not
AwardWallet’s terms summary, drawn from Southwest’s promotion detail, says all Southwest fare types can qualify, including Basic, Choice, Choice Preferred, and Choice Extra. Cash, Rapid Rewards points, and Cash + Points bookings can qualify when other rules are met.
Excluded categories named in the same reporting include Companion Pass reservations, charter flights, group travel, and Getaways by Southwest packages. Those do not count as the qualifying one-way or round-trip flights for this promo.
Changes matter. Southwest has historically allowed itinerary changes during a short booking window if the new trip still meets the rules, while post-window changes can disqualify the offer. Treat any rebook after August 6 as a risk until Southwest’s account tools confirm the trip still qualifies.
Southwest also says, per the specialist summary, that it will email qualifying members within about 10 days after requirements are complete, but the promotional Companion Pass itself posts for use on January 5, 2027. You can plan and even book your own early-2027 travel earlier, but you cannot designate the companion or attach the free companion reservation until the pass is on the account.
How this differs from a full Companion Pass
A standard Companion Pass earned by flying or points is one of the strongest domestic airline perks in the United States because the companion flies with you for taxes and fees across a long validity period. Deep Arrival’s Southwest Airlines guide explains why that full product remains a planning target for couples and parent-child travel.
This promo is narrower. The companion benefit lasts only from January 5 to March 3, 2027. There are no blackout dates inside that window in the reported terms, but the calendar is short. If your shared travel sits in summer 2027 or later, this promo does not help unless you also earn a regular Companion Pass.
Companion designation changes are limited. Reporting says you can change the designated companion up to three times during the promotional period, and those changes can reduce the three changes allowed if you later earn a full 2027 Companion Pass. Couples who might swap companions should count carefully.
Taxes and fees still apply to the companion. The free part is the Southwest base fare on eligible flights, not every government charge.
Who should register this week
Register if you already planned Southwest travel between now and mid-November and can complete one round trip or two one-ways under your Rapid Rewards number. The marginal cost can be near zero if the flights were already on the calendar.
Register and book a cheap short-haul round trip if you can use companion travel in January or February 2027 and the fare math still works after taxes. A low midweek domestic fare can be a rational “buy-in” if you will take several companion trips in the promo window.
Skip the promo if you have no Southwest itinerary before November 18 and no shared travel need in early 2027. Do not invent flying solely for a two-month companion window unless the companion trips are already valuable.
If you already hold or will soon earn a full Companion Pass, read how Southwest counts designation changes across the promo and the regular product. Stacking both is possible for some members, but the change-limit interaction is real.
For cabin and bag context on the same carrier, keep the sitewide carry-on size chart handy when you price whether a Basic fare “buy-in” trip is worth the hassle of tighter boarding and bag rules.
Step-by-step before August 6
First, log into Rapid Rewards and open the live promotion detail for this campaign. Confirm the dates on screen match August 6 book-by, November 18 travel-complete, and January 5 to March 3, 2027 companion validity. Screenshot the page.
Second, register before you buy. Registration is not optional on this structure. Book only after registration shows complete.
Third, book one round trip or two one-ways with your Rapid Rewards number attached. Prefer itineraries you would take anyway. Avoid Getaways packages and group blocks that the promo excludes.
Fourth, fly the trips by November 18 and keep boarding passes and confirmation emails. Watch for Southwest’s qualification email after travel completes.
Fifth, in late December or on January 5, confirm the promotional Companion Pass posts, then designate your companion and add companion seats only on flights with open capacity. Do not assume every January flight still has companion inventory at the last minute.
If Southwest’s account tools show different dates than this article, trust the live account page for your membership. Promotions can be account-targeted or updated, and the logged-in promotion detail is the controlling surface for registration.
| If you… | What to do |
|---|---|
| Already fly Southwest before mid-November with a frequent companion | Register now, attach your Rapid Rewards number, and complete one RT or two one-ways by November 18. |
| Need companion travel only in January or February 2027 | Price a cheap qualifying trip this fall against the early-2027 companion savings. |
| Have no fall flying and no early-2027 shared trips | Skip the promo; do not manufacture mileage runs for a two-month pass. |
| May earn a full 2027 Companion Pass later | Limit designation changes during the promo so you keep later change rights. |
| See different dates in your Rapid Rewards account | Follow the live promotion detail for your login; screenshot before you book. |
- By August 6: Register first, then book one RT or two one-ways with your Rapid Rewards number.
- Through November 18: Complete the qualifying flying without excluded package types.
- Around January 5, 2027: Confirm the promotional pass posts before designating a companion.
- January 5 to March 3, 2027: Add companion seats only when capacity allows; taxes and fees still apply.
- Changes: Avoid post-window itinerary edits that can void qualification.
Register only if the fall flying and the early-2027 companion window both fit trips you will actually take.
