Crazy. Credit card companies made $200 billion last year from swipe fees while spending just a fraction on airline miles for rewards cards. Meanwhile, almost everything you buy is more expensive -- even if you never use a credit card -- because of these hidden fees.
You might say that in some cases, instead of having airlines that run a credit card deal on the side, we have credit card companies that subsidize the air travel industry on the side. Courtney Miller observed last year, “No network airline made money moving people and things in 2024, including United Airlines and Delta Air Lines.”
Credit card companies purchase frequent flyer miles from the airline and reward them to the credit card user. Sometimes the credit card user redeems the miles and flies somewhere, but sometimes they don’t. But to the airline, it doesn’t matter that much, because the credit card company has already bought the miles and provided that revenue. In 2024, because of these payments from credit card companies, United, Delta, American, Southwest, and Alaskan Air all made operating profits.
Spirit Airlines had a credit card partnership with Bank of America. But this is another situation where large airlines have an advantage over smaller ones. After all, would you rather have a credit card and frequent flyer miles and potential free trips on a large airline that flies many places, or a smaller one that flies fewer places?
