Southwest Companion Pass: The Complete 2026 Guide

The Southwest Companion Pass is the single best value in US loyalty travel: fly with a designated companion for free — just taxes and fees — on every Southwest flight you book, for up to two years. Earning it takes 135,000 qualifying points in one calendar year, and the math changes by a full year of value depending on whether you cross that line in January or December. Most people who "hear about" the Companion Pass never earn it because they don't understand the timing, and most people who do earn it never use it efficiently because they don't understand what it isn't good for.

Quick answer

You qualify for the Companion Pass by earning 135,000 Companion Pass–qualifying points in a single calendar year (Jan 1–Dec 31), or by flying 100 qualifying one-way flights in that year. Once earned, the pass is valid through the rest of that year plus the entire next calendar year — earn it in January and you get nearly two years of value; earn it in December and you get barely one.

• Card welcome bonuses, everyday card spend, and flights all count toward the 135,000-point threshold
• Southwest cardholders get a 10,000-point Companion Pass-qualifying bonus every account anniversary, which stacks toward requalifying
• You can change your designated companion up to three times per calendar year
• It is a 2-person benefit only — it does not cover a second child, a group, or lap infants (who already fly free)
• SW Priority ($229 AF), Southwest Premier ($149 AF), and Southwest Plus ($99 AF) are the three personal cards whose welcome bonuses count toward qualification

Key takeaway: 135,000 points in one calendar year earns the pass; earning it in January instead of December is worth roughly a full extra year of free companion flights for identical effort.

What actually counts toward the 135,000-point threshold

Companion Pass–qualifying (CP) points reset to zero every January 1 — nothing carries over from a prior year's partial progress.

What counts: base points earned flying Southwest, a Southwest credit card's welcome bonus once it posts, ordinary card spend as it posts to your Rapid Rewards account (points count on the statement-close date, not the purchase date — a December purchase that posts in January counts toward the new year), and the 10,000-point Companion Pass-qualifying anniversary bonus every Southwest cardholder receives each account year.

What doesn't count: points transferred in from Chase Ultimate Rewards (Southwest has no such transfer path — Rapid Rewards isn't a Chase transfer partner), and points earned through non-qualifying partner promotions that Southwest explicitly excludes from CP-qualifying status in the fine print of that promotion.

💡 Pro tip — Because points count on the date they post to your account, not the date you spend, a large purchase on December 28 that doesn't close until January 3 pushes those points into the following year's count. Time a big minimum-spend push around your statement date, not the calendar date, if you're straddling year-end.

Key takeaway: 135,000 CP-qualifying points reset every January 1; welcome bonuses, everyday spend (counted at posting, not purchase), flown points, and the annual 10,000-point cardholder bonus all count toward the total.

The two-year window: why January beats December by a full year

This is the single most important timing decision in the entire Companion Pass game, and it's the one most people never think about.

The pass is valid through December 31 of the year after you earn it — regardless of which month inside the qualifying year you cross 135,000 points.

• Earn it in January 2026 (say, by combining a welcome bonus with early-year spend): the pass is valid from the day you qualify through December 31, 2027 — roughly 23 months of free companion flights.
• Earn it in December 2026 (say, by grinding out the last few thousand points before year-end): the pass is valid from the day you qualify through the same December 31, 2027 — as little as 13 months.

Same 135,000-point effort. Same annual fees. Up to 10 fewer months of value for qualifying late in the year. If you're within striking distance of 135,000 points in November or December, the calculation isn't "should I push to finish this year" — it's "am I close enough that finishing now still beats waiting three weeks and restarting the clock on January 1 with a full 23-month runway instead."

⚠️ Biggest mistake — Grinding out the Companion Pass in November or December without checking how close you are to a full calendar year of runway. Someone who finishes at 135,000 points on December 15 gets roughly half the pass duration of someone who times the same effort to land in mid-January instead — for the identical point total.

Key takeaway: earning the Companion Pass in January instead of December is worth up to 10 additional months of free companion flights, for the same 135,000 points — timing inside the qualifying year matters as much as hitting the number.

Card-bonus path vs. flying path — and the break-even math

The flying path requires 100 qualifying one-way flights on Southwest in a calendar year — roughly two flights every week, viable only for genuine road warriors, not an average family building the pass once.

The card-bonus path is how nearly everyone actually gets there. Southwest's three personal Rapid Rewards cards — Southwest Plus ($99 AF, full review), Southwest Premier ($149 AF, full review), and SW Priority ($229 AF, full review) — each carry a welcome bonus that counts in full toward the 135,000-point threshold, plus the 10,000-point anniversary CP bonus every year after. Southwest and Chase run elevated Companion Pass–specific promotions periodically (an "earn the pass with one card" offer ran in early 2026, for example); these are time-limited and worth checking for before you apply, but the baseline math works without one: stack a card welcome bonus with several months of ordinary spend (Southwest points earn on every purchase at 1–2x depending on the card, higher on Southwest-direct spend) and most travelers with typical annual spending clear 135,000 points inside 6–9 months. See the Southwest Rapid Rewards program guide for how the points themselves earn and redeem outside the Companion Pass math, and Southwest card vs. Chase UR for Southwest if you're deciding whether a co-brand card or transferring Chase Ultimate Rewards points gets you there faster.

Business cards — Southwest Premier Business ($149 AF) and Southwest Performance Business ($299 AF) — also earn into the same Rapid Rewards account and count toward the same threshold if you have qualifying business spend, effectively giving a two-card household two welcome bonuses toward one shared 135,000-point target.

Break-even math: a companion's one-way fare on a typical domestic Southwest route runs $120–$220; a round trip together, where only your own ticket is paid, saves $220–$440 in a single trip.

Key takeaway: the flying path (100 one-ways) is impractical for most people; the card-bonus path clears 135,000 points inside 6–9 months for a typical spender, and the pass pays for its annual fee after as few as 2–3 round trips with your companion.

Changing your companion, and what the pass is not good for

Southwest lets you change your designated companion up to three times per calendar year — four different companions total across a year, counting your original pick. Changes require a phone call to Southwest reservations, not a self-service web change, and your prior companion must be removed from any future bookings before a new one can be added.

What it is NOT good for:

• Solo travelers. The entire value is a second free ticket — if you rarely travel with the same person, the pass has nothing to attach to.
• One-and-done trip takers. If you won't fly Southwest with a companion at least 2–3 times before the pass expires, the AF on the qualifying card(s) likely exceeds the savings.
• International or partner-airline redemptions. The pass rides on Southwest-marketed flights, including Southwest's own international routes to Mexico, the Caribbean, and parts of Central America — it does not extend to any partner or codeshare carrier.
• Infants and additional children. Lap children under 2 already fly free with or without the pass. Any child 2 or older needs a full fare of their own — the Companion Pass covers exactly two people, you and one designated companion, not a family unit.
• Travelers outside Southwest's route map. If your regular trips aren't on routes Southwest serves well from your home airport, the free-companion-seat math never gets a chance to pay off.

Key takeaway: the Companion Pass rewards frequent-flying pairs on Southwest's own route map — it adds nothing for solo travelers, one-time trips, international partner redemptions, or families needing more than two seats covered.

Real use case: a family's two-year Companion Pass math

Sam and Priya fly Southwest for family visits three to four times a year and want to add a couple of leisure trips. Sam applies for SW Priority in early January 2026, clears the welcome bonus plus normal annual spend, and crosses 135,000 CP-qualifying points by mid-February 2026. Sam designates Priya as the companion.

Because they qualified in February 2026, the pass is valid through December 31, 2027 — roughly 22 months of runway. Over that window they take six round trips together: three family visits and three short leisure trips, averaging $260 per round trip for what would have been Priya's ticket. Total saved on Priya's fares: $1,560. Against that, they pay the $229 annual fee twice across the two-year window ($458 total), for a net savings of roughly $1,100 — before counting the free checked bags and other card perks that ride along with SW Priority.

Had Sam instead crossed the same 135,000-point threshold in December 2025, the pass would have expired at the same December 31, 2027 date but started 11 months earlier in usable runway lost — realistically fitting three round trips instead of six, roughly $780 in savings instead of $1,560, for the identical amount of card spend and the identical annual fee. The point total was the same; the calendar timing halved the value.

For a family already planning a big-ticket trip, pairing the Companion Pass with a points-funded flight — see flights to Hawaii on points for how far US carriers' miles stretch to Honolulu — multiplies the savings further, since the companion's seat on any Southwest connecting segment is also free.

Key takeaway: qualifying in February instead of December on identical spend nearly doubled this family's realistic savings, from about $780 to $1,560, purely because of an 11-month difference in usable pass runway.
