The phrase "miles that never expire" gets used loosely in airline-card marketing. The honest version is narrower and more useful: four major U.S. airline programs have permanently removed expiration on their points, and the cobranded credit cards from those programs are the easiest way to keep adding to a balance you do not need to babysit. Delta SkyMiles, United MileagePlus, JetBlue TrueBlue, and Southwest Rapid Rewards all sit in this category as of April 2026. American AAdvantage is the major outlier, and we will get to it.

The cards below are the ones worth carrying if your goal is a points balance you can leave alone for a year, two years, ten years, and still find intact when you go to redeem. We will walk through each issuer's lineup, who each tier is for, the fee structure, and the standout earning categories.

Why Permanent No-Expiration Matters

Mile expiration is a quiet wealth tax on infrequent travelers. A 100,000-mile balance, easily worth $1,500 to $2,000 in award flights, can disappear in 18 to 36 months of inactivity in programs that still enforce expiration. The four programs covered below removed that risk entirely:

  • Delta SkyMiles dropped expiration in 2011.
  • United MileagePlus dropped expiration in August 2019.
  • JetBlue TrueBlue dropped expiration in 2013.
  • Southwest Rapid Rewards dropped expiration in 2019.

Earn miles in any of these programs today, and they will be in your account in 2050 if you do nothing. No activity required. No fine print. The cobranded credit cards just make the earning easier, faster, and tied to the spending you do anyway.

Delta SkyMiles Cards (Gold, Platinum, Reserve)

Delta runs three Amex cobranded tiers. All three earn SkyMiles that never expire.

The Delta SkyMiles Gold ($150 annual fee) earns 2x on Delta purchases, 2x at U.S. supermarkets, and 2x at restaurants worldwide. Standout perks include a free first checked bag for the cardholder and up to eight companions on the same reservation (saving $35 each way per person), priority boarding, and 20% back on in-flight purchases as a statement credit. The supermarket multiplier is rare on a sub-$200 card and pulls the Gold into wallets that would not otherwise touch a Delta product.

The Delta SkyMiles Platinum ($350 annual fee) layers on a domestic main cabin Companion Certificate every year on the cardholder's account anniversary, plus an annual $120 Resy credit and an annual $150 rideshare credit. The earn structure adds 3x on Delta purchases and 3x on hotels booked direct. The Companion Certificate alone, at typical valuations of $200 to $400 in retail fare savings on a domestic Delta round trip, can offset most or all of the annual fee.

The Delta SkyMiles Reserve ($650 annual fee) is the lounge card. It includes Delta Sky Club access when flying Delta same-day, a Companion Certificate valid in first class or Comfort+ (a meaningful step up from the Platinum's main-cabin version), $240 in annual Resy credit, $120 in annual rideshare credit, and 3x on Delta purchases. The break-even math here depends entirely on lounge usage and the Companion Certificate. Two domestic first class round trips a year for two passengers, paired with even moderate Sky Club access, clear the fee.

Best for: Delta Gold suits a family that flies Delta two to three times a year and wants the bag savings. Platinum is the move if the Companion Certificate fits your travel pattern. Reserve fits genuine Delta loyalists who use the lounge.

Outclassed for: A traveler who flies Delta once a year. The bag credit and the welcome bonus are the entire ROI in that case, and the no-fee Delta Blue card may be the better fit.

United MileagePlus Cards (Explorer, Quest, Club)

United runs three Chase cobranded tiers. All three earn MileagePlus miles that never expire.

The United Explorer ($0 the first year, $95 thereafter) earns 2x on United purchases, dining, and hotel stays booked direct. Benefits include a free first checked bag for the cardholder and one companion (saving $70 round trip per person), priority boarding, two one-time United Club passes per year, a Global Entry or TSA PreCheck application credit, and primary auto rental coverage on United bookings.

The United Quest ($250 annual fee) earns 3x on United purchases, 2x on travel, dining, and select streaming services, and 1x elsewhere. The Quest comes with $200 in annual United travel credits and a 5,000-mile award flight rebate (good twice per year, for up to 10,000 miles back on award redemptions). The card also includes free first and second checked bags for the cardholder. Heavy United award redeemers extract the most value here, since the rebate effectively discounts up to two domestic award trips per year.

The United Club Card ($695 annual fee) is the lounge tier, with full United Club membership for the cardholder (a benefit that retails at $750 a year if purchased standalone), 1.5x on all purchases, free first and second checked bags for the cardholder and a companion, primary auto rental coverage, and a Global Entry or TSA PreCheck credit. The math on this card is roughly: if you would otherwise pay for United Club access, the card pays for itself before you count any other benefit.

Best for: Explorer fits the occasional United flyer who values the bag credit. Quest is the sweet spot for active United loyalists. Club is for genuine lounge users.

Outclassed for: A traveler who only takes one United flight a year and does not need lounge access. The Explorer's first-year free fee makes it a low-risk way to grab the welcome bonus.

JetBlue Plus Card

The JetBlue Plus ($99 annual fee, issued by Barclays) earns 6x TrueBlue points on JetBlue purchases, 2x at restaurants and grocery stores, and 1x elsewhere. The 6x rate is the highest cobranded earning rate on any U.S. airline card. Card benefits include a free first checked bag for the cardholder and up to three companions (saving $40 each way per person), 50% in-flight savings on purchases, a 10% TrueBlue rebate when you redeem points, and a 5,000-point anniversary bonus every cardholder anniversary.

TrueBlue points do not expire. The 5,000-point anniversary bonus is worth roughly $65 to $75 at typical TrueBlue redemption values of 1.3 to 1.5 cents per point, which alone covers most of the annual fee for cardholders who use the card primarily on JetBlue spend.

Best for: Northeast flyers who use JetBlue regularly for transcontinental routes, particularly out of JFK or Boston. Families benefit most from the bag credit.

Outclassed for: Travelers who fly JetBlue once or twice a year. The no-fee JetBlue Card earns 3x on JetBlue and 2x on dining at $0 fee, which works out better at low usage levels.

Southwest Rapid Rewards Cards (Plus, Premier, Priority)

Chase issues three Southwest cobranded cards. All three earn Rapid Rewards points that never expire.

The Southwest Rapid Rewards Plus ($69 annual fee) earns 2x on Southwest purchases, 2x on local transit and rideshare, 2x on internet, cable, phone, and select streaming, and 1x elsewhere. Cardholders receive a 3,000-point anniversary bonus, two EarlyBird Check-In credits per year, and 1,500 tier qualifying points per $10,000 spent (which contributes toward A-List status). The Plus is the cheapest path into the Southwest cobranded ecosystem and a reasonable "expire-protection plus light benefits" pick.

The Southwest Rapid Rewards Premier ($99 annual fee) earns 3x on Southwest, 2x on transit, rideshare, internet, and streaming, with 1x elsewhere. The anniversary bonus rises to 6,000 points, and the card includes no foreign transaction fees. The Premier slots in for travelers who want a moderate step up from the Plus without paying the Priority's premium.

The Southwest Rapid Rewards Priority ($149 annual fee) earns 3x on Southwest, plus the same 2x categories as the Premier. The Priority comes with a $75 annual Southwest travel credit (effectively dropping the net annual fee to $74), four upgraded boardings per year (a $30 to $80 value each, depending on route), 25% in-flight savings, a 7,500-point anniversary bonus, and 1,500 tier qualifying points per $5,000 spent.

For Southwest loyalists, all three cards count the same way toward the Companion Pass: spend that earns Rapid Rewards points (excluding the welcome bonus on most years) contributes toward the 135,000-point qualifying threshold. Pairing two Southwest cards (one personal, one business) is the standard playbook for hitting the Pass faster.

Best for: Plus suits the occasional Southwest flyer who wants permanent points and basic perks. Premier sits between casual and frequent. Priority pays back its fee for travelers who use the credit and the upgraded boardings.

Outclassed for: A traveler who never flies Southwest. The points are useful only on Southwest, with no transfer partner network outside the airline itself.

The American AAdvantage Caveat

American AAdvantage is the major U.S. program that still expires miles. Inactivity for 24 months wipes the balance, and the policy applies to the entire account, not individual mile lots. This is the most relevant exception to the "permanent miles" framing, and it is the reason carrying an AA cobranded card has a different rationale from carrying a Delta or United one.

Any single qualifying activity resets the 24-month clock. A purchase on the Citi AAdvantage Platinum Select ($99 annual fee) or the Barclays AAdvantage Aviator Red ($99 annual fee) generates miles that post within a billing cycle, which counts as activity. Cardholders who use either card at all during a 24-month window keep their AAdvantage account permanently active.

Both cards earn 2x on American purchases. The Citi card adds 2x on dining and gas. The Aviator Red has historically offered a generous welcome bonus structure that requires only a single purchase plus the annual fee, making it the cheaper short-term option in years when the bonus is strong.

For a pure activity-shield use case where you do not want to pay $99 annually, two free alternatives exist: a $1 transaction at any American SimplyMiles dining-portal restaurant earns miles and resets the clock, and a 1,000-point transfer in from Bilt Rewards (one of AAdvantage's transferable-points partners) accomplishes the same thing.

How to Pick

The decision tree is short. Start with the airline you actually fly. If your home airport is dominated by Delta, the Delta cards make sense. If you live near a Southwest hub, Southwest cards make more sense than chasing United status you will never use.

Tier within an issuer comes down to three questions: do you fly enough to use the bag credit and priority boarding, do you want lounge access, and does the next-tier annual fee math out against the credits and bonuses you would actually use? The mid-tier card (Delta Platinum, United Quest, Southwest Priority) tends to be the strongest fit for active flyers who do not need lounge access. The entry-tier card (Delta Gold, United Explorer, Southwest Plus, JetBlue Plus) is the right pick for casual flyers who mainly want the bag credit and a permanent points balance.

Because the underlying programs (Delta, United, JetBlue, Southwest) do not expire miles at all, the cobranded card is not a defensive purchase. You hold it for the ongoing benefits and the welcome bonus, and the balance you build sits there permanently as a side effect.
