Last Call on Southwest Companion Pass Promotion 2025: Easy Path to 2-for-1

Looking for the easiest path to two-for-one flights next year? The Southwest Companion Pass promotion 2025 makes it simple: register, book one round trip (or two one-ways) by August 28, 2025, and fly by November 15, 2025 to unlock a promotional Companion Pass valid January 6–March 6, 2026. Basic fares don’t qualify, but points and Cash + Points bookings do. Below, we break down eligibility, key dates, and smart ways to squeeze maximum value from this limited-time offer.

The offer in 60 seconds

• Register first (free), then book 1 round trip or 2 one-ways by by 11:59 p.m. CT on 28 August 2025 (Thursday).
• Travel by Nov 15, 2025.
• Earn a 2-month Companion Pass valid Jan 6–Mar 6, 2026.
• Basic fares are excluded; award tickets and Cash + Points do qualify.

How to qualify (step-by-step)

1. Register for the promo (must be done before any qualifying booking).
2. Book a qualifying round trip or two one-ways on Southwest between Aug 25–28, 2025 (direct with Southwest).
3. Fly your booked trip(s) by Nov 15, 2025.
4. Your promo Companion Pass will post, letting a chosen companion fly with you for just taxes/fees during Jan 6–Mar 6, 2026.

Heads-up on changes: The terms require the qualifying booking (and any changes) to be made during the Aug 25–28 window; changing later can void eligibility. Previously booked trips don’t count—newly ticketed after registration only.

What Counts (and what doesn’t)

• Counts: Paid fares above Basic, award redemptions, and Cash + Points bookings made during the promo window.
• Doesn’t count: Basic fares, Southwest Vacations packages, charter/group bookings, or anything booked before registering.

How the Companion Pass Works During the Promo Window

From Jan 6 to Mar 6, 2026, you can add your designated companion to your Southwest flights for only the taxes/fees (from $5.60 one-way). You can change your companion up to three times per calendar year.

Is it worth it? A quick reality check

If you can line up one or two trips in early 2026, this is an easy win:

• Suppose you spend ~$120 on a cheap round trip now to trigger the pass.
• Use the pass for a $230 round-trip in February 2026—your companion pays only ~$11.20 in taxes.
• You’ve effectively saved ~$218 on that one booking, more than covering the cost to trigger the pass—and you can use it again within the two-month window (subject to seat availability).

If you won’t fly in Jan–Feb 2026, or you only ever buy Basic fares, skip it.

How this promo compares to the “real” Companion Pass

The standard Companion Pass requires 100 one-way flights or 135,000 qualifying points in a calendar year and is valid for the rest of that year plus the entire next year. The promo version is far easier to earn but only lasts two (2) months.

Pro tips (to squeeze extra value)

• Book smart routes: Short hops and off-peak itineraries are often cheap, making the trigger cost low.
• Stack with points: If cash prices are high, use points or Cash + Points—these still qualify for the promo when booked in the window.
• Mind the fare class: Don’t accidentally pick Basic—it won’t qualify to earn the pass (you can still use a Companion Pass on Basic you buy later, but Basic won’t earn it).
• Already booked? You could consider canceling and rebooking after registering if the price is similar (Southwest has no change/cancel fees), but ensure your new ticket is issued within Aug 25–28.

Bottom line

If you can register today and book a quick qualifying trip, this is one of the lowest-effort paths to two months of two-for-one flying on Southwest. Time it with winter travel and you can come out well ahead—even if the trigger flight is a cheap positioning hop.
