The focus has changed where U.S. airlines have long been relying on frequent-flyer programs to retain passengers. A large percentage of the loyalty revenue is done today based on credit-card expenditure rather than ticket purchase. The transformation, which was prompted by the post-pandemic healing, favors the daily shopping experience over bookings of flights.
The Rise of Co‑Branded Cards
American express, Chase and Citi co-branded credit cards have become cash machines in the airline industry. Groceries, gas, and streaming services are the categories of products whose customer will earn miles much more than the airfare. Most of these deals enable major U.S. airlines to generate loyalty programs that amount to $36 billion in 2025.
Delta Air Lines held the first position with American Express alone standing at $8.2billion, almost as much as its ticket-sales revenue. Blue American made its partners contribute to its revenue to the value of 6.2 billion, four times more than its adjusted operating income. Alaska Airlines and United came next, and the loyalty revenue constituted 16 per cent of the total income of Alaska. Miles are bought in large quantities by banks who resell them using cards generating a continuous stream of income which falls to offset ups and downs in flight demand.
New Loyalty Regulations Favor Cardholders.
The airlines are re-engineering programs to enable users of credit-cards. United Airlines will start to implement changes on April, 2026: non-cardholders obtained only 3 miles per dollar during flights whereas cardholders will receive at least 6. Basic-economy flights offer miles to the cardholders only. American Airlines reduced the earnings rates on its lowest fares, pushing flyers to the higher fares or credit cards.
This movement reduces the experience of low-cost travelers. The report on IDEAWorks 2025 reveals that reward payback, the value of miles in comparison to the cash ticket, has reduced by half in comparison to 2019. One reason given by airlines to justify the change is that they are targeting the high-value customer, yet according to critics, this reduces the value of miles to an average customer.
Breakdown of revenue in Numbers.
The core flying profits are now competed or surpassed by the loyalty revenue as indicated below.
| Airline | 2025 Loyalty Revenue | % of Total Revenue | Key Partner |
|---|---|---|---|
| Delta Air Lines | $8.2 billion | ~50% | Amex​ |
| American Airlines | $6.2 billion | >100% of adj. income | Citi​ |
| United Airlines | Significant share | High | Chase​ |
| Alaska Airlines | 16% of total | 16% | Bank of America​ |
These values signify the impact of card cash to stabilize earnings through fuel expenses and rivalry.
Challenges and Pushback
Airline miles are threatened by the cash-back boom offered by general reward cards like Chase Sapphire. Essence of easier cash deals will make users quit complicated mile plans. These arrangements are being questioned by regulators; the proposed Credit Card Competition Act might increase merchant charges, decreasing the buying power of banks on the mile, and killing programs.
The pain is experienced by the consumers: tightened sword strokes and watered down miles weaken confidence. Airlines respond to it by providing such benefits as a free baggage and lounge access to card owners, yet startups attract unhappy travelers with more accessible rewards.
Future Outlook for Flyers
In the future, more card integration will be anticipated. Airlines can also package status benefits and expenditure limits, further mixing flying and money. However, as the economy becomes uncertain, excessive dependence on cards could be devastated in case the banks withdraw. The flyers must balance the card charges against utility because the actual worth is concentrated use.
This transformation highlights how the airlines have shifted to financial services where plastic swipes make more profits compared to takeoffs.
