The annual airline credit card debate is back, and this time it's playing out between two loyalty heavyweights. On the Airlines Confidential podcast, former American AAdvantage president Maya Leibman argued for the simplicity of airline and hotel cards, while travel writer Ed Pizzarello championed flexible bank points. Leibman summed up the airline view with a quote she remembered from another former loyalty chief: people will pay anything for a free flight.

View from the Wing's take cuts through that sentiment, and it's worth understanding before you swipe. Airline cards earn their keep in two ways that have nothing to do with everyday spending: a chunky sign-up bonus, and perks attached to simply holding the card — free checked bags, priority boarding, lounge access, anniversary certificates. If those benefits outweigh the annual fee, the card pays for itself even if it lives in a drawer. But that doesn't make it your default payment method.

The maths on spending is the part that stings. Put $30,000 on a card earning one airline mile per dollar and you get 30,000 miles. The same spend on a 2% cash-back card earns $600. If those miles get you a flight you could have bought for $300, you've effectively given up $600 to save $300. Unless the miles land you something you'd genuinely pay a premium for — long-haul business class redemptions are the classic case — airline miles earned at 1x are a poor return.

The good news is you don't have to choose. Flexible bank currencies like Chase Ultimate Rewards or Bilt can be transferred into airline programmes when you actually find an award worth booking. American, historically hard to reach from transferable points, is now a Citi transfer partner, so cards like the Citi Strata Premier can feed AAdvantage miles while keeping your options open. And there are legitimate reasons to put real spend on an airline card: American's cards earn uncapped Loyalty Points towards status, and some business cards can generate status credit for both the primary cardmember and an employee on the same purchase.

The practical takeaway for travellers: get the airline card that matches the airline you fly for the bags and boarding, grab the sign-up bonus, then route the rest of your spending to whichever card earns you the most — checking that any point multiplier times the value per point actually beats a simple 2% back. Simplicity is nice; hundreds of dollars in lost rewards each year is not.
