If you fly one airline consistently, a co-branded card earns the most miles in that program and adds trip perks — free checked bags, priority boarding, companion passes — that can outrun the annual fee on their own. If your routes change or you want aspirational redemptions, a transferable-currency card beats every co-branded card on flexibility. We rank by the value a normal flyer actually captures, not the miles-times-issuer-valuation headline.
How we ranked this list
Ranked by ClearValue Score. Co-branded perks (bag fees, companion passes) are valued at realistic annual capture and weighed against the fee; miles are valued at conservative program benchmarks, never issuer valuations. A card whose perks you cannot use does not out-rank a simpler one.

Pros
Southwest loyalists chasing the Companion Pass — 7,500 anniversary points, 4x earning on Southwest purchases, and uncapped 2x at gas stations and restaurants. Stacked with Southwest's free-checked-bag policy, the AF math still works if you fly enough to justify the $229 fee.
Trade-offs
Travelers who fly other airlines internationally (Southwest's network is U.S. + Caribbean only), anyone not chasing the Companion Pass, and infrequent flyers who won't clear the $229 AF — the entry-tier Southwest Plus is closer to right for casual Southwest flyers.
The catch
Chase raised the annual fee from $149 to $229 in its 2025 refresh (effective immediately for new cardholders, at the 2026 renewal date for existing ones) and swapped the $75 annual Southwest travel credit and 4 upgraded boardings/yr for uncapped 2x at gas/restaurants and 4x (up from 3x) on Southwest purchases — run the new perk mix against your actual spend before assuming it clears the higher AF. Beyond that, the Companion Pass is still the cardholder's real reason for being: it takes 135,000 qualifying points in a calendar year, which the card's earning rate alone won't reach — the sign-up bonus + spend is the calculus.

Pros
Alaska and Hawaiian Airlines flyers — especially on the West Coast — who want an annual $99 companion fare (plus taxes and fees from $23), a free first checked bag, priority boarding, and 3x points on Alaska/Hawaiian purchases, with no foreign transaction fee. Bank of America renamed the card the Atmos Rewards Ascent Visa Signature after Alaska and Hawaiian merged their loyalty programs into Atmos Rewards.
Trade-offs
Travelers who rarely fly Alaska or Hawaiian (the companion fare requires spending $6,000+ in the prior anniversary year) and anyone wanting flexible points — Atmos Rewards points (formerly Alaska Mileage Plan miles) are valuable but locked to Alaska, Hawaiian, and their partners.
The catch
The $95 annual fee is not waived in year one, so value has to start immediately — and it usually does through the companion fare, which can exceed the fee on a single use. The card only makes sense if Alaska or Hawaiian is genuinely in your rotation; existing cardholders kept the same account and terms through the Atmos Rewards rebrand, no reapplication needed.

Pros
Travelers loyal to United who fly 2-4 round trips a year, want a free checked bag, and value priority boarding + 2× United-spend earning.
Trade-offs
Star Alliance optimizers chasing aspirational redemptions (the United Quest or Club Infinite open up better partner award charts) and anyone who flies United less than twice annually.
The catch
Chase raised the annual fee from $95 to $150 for cardholders on or after January 1, 2026 ($0 intro the first year for new applicants) — the 25k bonus miles for two checked bags + the free first checked bag are the math-makers that offset it. If you and a travel partner each pack carry-on only, the value collapses fast — score the card around bag-checked round trips, not nominal mile-earn.

Pros
American Airlines loyalists who want a free first checked bag (for the cardholder and up to four companions on the same itinerary), preferred boarding, and 2x miles on American, dining, and gas — at a $99 annual fee that's waived the first year.
Trade-offs
Infrequent AA flyers (the free-bag benefit has to cover the $99 renewal fee to pencil out) and travelers who spread flights across airlines — a flexible transferable-points card serves them better than a single-carrier co-brand.
The catch
The first-year fee waiver gives you a year to prove the value before the $99 hits. The math rides almost entirely on the free checked bag — a couple of round trips with bags typically covers the fee, but only if you fly American regularly.

Pros
Travelers who fly Delta 2-4 times a year, want a free checked bag (~$70 saved per round trip per bag), and don't want to commit to a Platinum or Reserve tier annual fee.
Trade-offs
Light flyers (the $0 first-year + $150 ongoing AF only pencils with 2+ round trips/yr) and Delta Diamond-aspirants who need the Platinum/Reserve MQM boosts.
The catch
Year-1 $0 AF is the hook — by year 2 the math demands ~2 round trips with checked bags annually just to break even on the AF. If you're flying Delta less than that, the Delta Blue (the $0 AF sibling) is closer to honest.

Pros
Delta flyers who take 4-8 round trips a year and will use the annual Companion Certificate (Main Cabin domestic round-trip for a partner) — at one transcontinental redemption a year, the cert clears the AF on its own.
Trade-offs
Light Delta flyers who can't reliably use the Companion Cert within 12 months (cert is the load-bearing value, not the MQM boost) and travelers eyeing Reserve-tier Delta benefits — at that volume, the Reserve Card math overtakes Platinum.
The catch
The Companion Certificate excludes Comfort+, First, and Delta One — Main Cabin only. Account for the gap if you typically book higher classes. Also: blackout dates apply.

Pros
Occasional Southwest flyers who want the entry-tier perks — 2x points on Southwest and on gas/grocery spend, a 3,000-point anniversary bonus, and an on-ramp toward the Companion Pass — without the Priority card's $229 AF.
Trade-offs
Companion-Pass chasers and frequent flyers — Priority's 4x Southwest earning and richer credits close the gap on its higher AF quickly for anyone flying Southwest regularly; Plus is built for lighter, occasional flyers.
The catch
Chase raised this card's AF from $69 to $99 in its 2025 refresh. At that price, Plus's perks (a 3,000-point anniversary bonus, 2x gas/grocery) are thin relative to no-fee cashback alternatives — the card mainly earns its keep if you're specifically building Southwest miles or working toward the Companion Pass threshold.

Frequently asked
Is a co-branded airline card worth it if I only fly one airline?
Yes, if you fly that airline at least a couple of times a year and check bags. The United Explorer Card's free first checked bag and priority boarding are the math-makers for United loyalists flying 2-4 round trips/yr; the Southwest Rapid Rewards Priority stacks Southwest's already-free checked bags with 4x earning on Southwest purchases and uncapped 2x at gas stations and restaurants. If your airline loyalty is loose, a transferable-currency travel card beats any single co-brand on flexibility.
What's the Southwest Companion Pass, and does the credit card get you there alone?
The Companion Pass lets you fly a designated companion free (taxes/fees only) on every Southwest flight you book for the rest of the year you qualify plus the following year — but you need 135,000 qualifying points in a calendar year to earn it. The Southwest Rapid Rewards Priority's ongoing earn rate alone won't get you there; it takes the card's sign-up bonus plus real spend to reach the threshold.
Do airline credit cards still waive foreign transaction fees?
The ones worth holding do — Alaska Airlines Visa Signature, United Explorer, Southwest Rapid Rewards Priority, Delta SkyMiles Gold, and Delta SkyMiles Platinum all charge 0% foreign transaction fee, so the co-branded perks (free bags, priority boarding) travel with you internationally without an added FX cost.
