Introduction

There are legion cards with airline incidental credits, which are obviously different than airline travel credits (a keen observer will note that they’re obviously different because one is “incidental” and the other is “travel”, duh). Examples:

  • American Express Platinum and Business Platinum
  • Bank of America Premium Rewards
  • PenFed Pathfinder
  • American Express Hilton Aspire
  • UnionBank Rewards
  • CNB National Crystal

The intended way to cash these out is for ancillary fees like checked bag charges, pet charges, in-flight purchases, and similar. But, turning them into airfare credits for future travel is usually mosre interesting and now that we’ve flown right past Martin Luther King Jr. Day, we’ve got sufficient datapoints to know what works for getting airfare instead.

If you’re too busy to care about reading further, the easiest option is the United TravelBank, which works for all card issuers. Flights booked with TravelBank funds also qualify for regular paid United benefits like a small snack and a surly flight attendant.

Methods for Airfare

Still with me? I don’t blame you, I like AA’s surly flight attendants 1.6% better than United’s surly flight attendants. Here’s what works in 2024:

  • United: Buy TravelBank credit directly. It expires in five years and can be used to pay for United flights; if you get an error during checkout at TravelBank, add your card to your United profile as a saved payment then try again. If you’re using another player’s card for your own account, use the gifting functionality at the same site instead [more info]
  • Delta: Buy airfare and pay partially with a gift card or travel credit, pay for the remainder with your card (don’t go over $250 in the remainder payment with American Express cards though). Alternatively if you have a co-branded American Express Delta card, pay partially with miles and the remainder will be credited [more info]
  • Alaska: Buy a flight that costs less than $100, then refund to your wallet after 24 hours [more info]
  • Southwest: Buy a flight less than $100, or book an international flight with taxes under $100 per ticket, then refund to a travel credit [more info]
  • Hawaiian: Buy airfare of $50 or less [more info]
  • American: Buy cheap airfare, then change it to a flight that you really want that costs more and pay with your credit card (don’t go over the credit amount though). If you want to gamble, you’ve got roughly even odds that award taxes and fees will count [more info]
  • JetBlue: Buy a flight less than $137 then cancel the flight after 24 hours and refund to your JetBlue wallet [more info]

Other Options

There are other non-airfare options that are probably unintended to be reimbursed but still are for most airlines (see each individual [more info] link), or you can stick to what AmEx HQ wants you to do like pay for in-cabin pets [more info, but corporate double-speak laiden].
