By Airline: Which Card Tier Is Right For You

Delta
SkyMiles Gold ($150)
Fly Delta 4-8 trips/yr. Free bag pays for most of the fee.
SkyMiles Platinum ($350)
Fly Delta 10+ trips/yr and want elite status acceleration and companion cert.
SkyMiles Reserve ($650)
Delta loyalists who want Sky Club lounge access and top elite benefits.
United
Gateway ($0)
Casual United flyer who wants miles without a fee.
Explorer ($95)
Best value. Free bag + 2 club passes easily worth more than the fee.
Quest ($250)
Heavy United flyers who check 2 bags or travel with a companion regularly.
Southwest
Plus ($69)
Light Southwest flyers. 3,000 anniversary points help offset the fee.
Priority ($149)
Best Southwest card. $75 travel credit and 7,500 anniversary points nearly pay the fee.
Alaska
Alaska Visa ($95)
Anyone who flies Alaska. The $99 companion fare certificate is worth well over the annual fee alone.

When to Skip the Airline Card

The airline card pitch is compelling but the math does not always work. Here is when a flexible card wins instead.

You fly less than 4 round trips per year

Below 4 trips, the bag savings rarely cover the annual fee. A no-fee flexible card earns comparable miles with no cost.

You book the cheapest fare, regardless of airline

An airline card ties you to one carrier's award inventory and pricing. A flexible card lets you book any airline through transfers.

You want business class redemptions

Co-branded miles are often more expensive for premium cabin awards than transferable points. Chase UR via United or Amex MR via Singapore typically offer better business class value.

You already fly free via elite status or employer perks

If your company pays for bags or you have status benefits, the main perk of the airline card has no value to you.

Frequently Asked Questions

Is an airline credit card worth it?
An airline card is worth it if you fly the same carrier at least 4-6 round trips per year and check bags. The United Explorer ($95/yr) saves $35 per bag each way, so one round trip with a checked bag = $70 saved, breaking even in less than two trips. If you fly multiple airlines or less than 4 times per year, a flexible rewards card usually delivers more value.
Which airline credit card gives the best free checked bag perk?
The United Explorer and United Quest offer free first checked bag for you and one companion on United flights, saving $35 per person each way. The Delta Gold, Platinum, and Reserve cards offer the same on Delta. The American Airlines card family also includes free bags. Southwest passengers get 2 free bags on all tickets regardless of card, so a Southwest card's bag perk is moot.
Should I get an airline card or a flexible rewards card?
Get an airline card if: you fly one carrier consistently, you check bags frequently, you want elite status boosts, or you have a specific redemption goal on that airline. Get a flexible card if: you book the cheapest option, you travel internationally on various carriers, or you want to maximise total point value through transfer partner sweet spots. Many optimisers hold both.
What is a companion pass and which cards offer it?
A companion pass lets you bring a designated companion on flights for free (or at reduced cost) for a set period. The most valuable companion benefit is the Southwest Companion Pass, earned by accumulating 135,000 points in a calendar year - the card sign-up bonuses can trigger this. Delta Platinum and Reserve cards offer a companion certificate, which works differently (one domestic main cabin flight per year after renewal). Alaska Airlines offers the most consistent annual companion fare at $99 plus taxes.
Which airline miles are worth the most?
Alaska Mileage Plan miles are generally the most valuable at around 1.7 cents each, partly because Alaska partners with many airlines and has sweet spot awards. American AAdvantage miles are worth about 1.6 cents each. United MileagePlus miles are worth about 1.4 cents each. Delta SkyMiles are worth around 1.2 cents each - Delta moved away from fixed award charts which reduced their value ceiling. Southwest Rapid Rewards are worth about 1.3 cents each and work best for domestic travel.
