Co‑branded credit cards have become a central lever in how U.S. airlines are reshaping their loyalty programs.

United Airlines: Card Ownership as a Core Earn Driver

  • United’s redesign makes mileage earning rates depend on whether a member holds a United co‑branded credit card, dropping non‑cardholder rates to as low as 3 miles per dollar while cardholders earn up to 12 miles per dollar for top‑tier status.
  • Basic Economy tickets now earn zero miles for non‑cardholders, creating a clear incentive to obtain a United card to receive any mileage credit.
  • Cardholders receive at least a 10 % discount on award tickets, with Premier elite members who also hold a card getting 15 % or more off, tying redemption savings directly to card ownership.
  • United highlights expanded access to lower‑priced Saver award inventory for cardholders, further differentiating the experience between card‑holding and non‑card‑holding members.
  • The airline frames these changes as “the most rewarding way to fly United,” positioning the credit card as the primary path to earn more miles faster and unlock premium award space.

Delta, American, and Other “Carrot‑Stick” Strategies

  • Delta emphasizes extra value for customers who already hold its co‑branded card, using the card as a carrot to boost loyalty benefits.
  • United adopts a “stick” approach, making the program work better for cardholders while reducing benefits for those without a card, effectively pushing travelers toward card adoption.
  • American Airlines turns card spending into a shortcut toward elite status, allowing frequent spenders to accelerate their tier progression through the co‑branded card.

Partnership Expansions and New Card Products

  • Alaska Airlines and Bank of America have extended their multi‑year co‑branded credit card agreement, promising incremental value, new card features, and enhanced benefits across the Atmos Rewards portfolio.
  • The partnership aims to deepen integration, increase investment in the loyalty brand, and eventually roll out refreshed card offerings that further tie credit‑card usage to program rewards.
  • Similar trends across the industry show airlines leveraging co‑branded cards not just as optional perks but as essential components of loyalty program redesigns, shaping earning structures, redemption discounts, and elite‑status pathways.

Airline Credit Cards Used to Be Optional. Not Anymore.
Airline loyalty programs generate billions of dollars in revenue each year from their co-branded credit cards. In many cases, those partnerships with banks are more profitable than selling airline tickets. So it’s no surprise that airlines keep looking for ways to encourage travelers to sign up for their cards. What’s interesting lately is that the three largest U.S. airlines seem to be taking very different approaches. Delta, United, and American are all pushing their credit cards harder than ever—but they’re doing it in very different ways. You could think of it as three different strategies: **Carrot.
