The quick verdict
For travel specifically, we would use a prepaid card rather than brand credit almost every time. Travel plans change, and the difference between a refund you can spend anywhere and a refund locked to one airline is worth more than the small difference in markup.
The exception is a brand you use constantly and a booking you are confident about. Then airline or Airbnb credit is fine, and occasionally discounted during seasonal promotions.
The discount that is not there
Search for crypto flight deals and you will find pages promising substantially cheaper travel for paying in Bitcoin. Read them carefully and the saving is almost always either a normal fare presented as a deal, or a promotional credit that any payment method would have earned.
The reason is structural. An airline sells a seat at a price set by its revenue management system. A reseller buying that seat pays the same price you would. There is no crypto wholesale market for air travel, and there is no margin for the reseller to give away. They are adding a markup, not removing one.
What crypto buys you in travel is access and speed. If your money is in crypto and your alternative is selling on an exchange, waiting for a bank transfer and hoping the fare holds, then paying directly is a real advantage even at a 5% markup. Fares move more than 5% on their own over three days.
The refund trap
This is the part that costs people money and almost nobody thinks about before booking.
When you cancel a booking, the refund goes back to the original payment method. If you paid with airline credit bought via a gift card, the refund returns as airline credit, not to your wallet, not to your bank, not as anything you can spend elsewhere. You are now holding credit with a company you may have no plans to fly with again, often with its own expiry window.
The crypto leg makes this worse rather than better. You cannot chargeback a crypto payment, you cannot return a revealed gift card code, and the marketplace you bought from has no relationship with the airline. Every party in the chain is behaving correctly and you still cannot get your money out.
Match the instrument to the certainty
Confident, non-refundable, brand you use often → brand credit is fine.
Flexible dates, comparison shopping, might cancel → prepaid card, so a refund stays
spendable anywhere.
Currency, twice over
Travel is the one category where you routinely pay a currency spread twice, and the second one is easy to miss.
The first conversion is crypto to the card’s denomination, which carries the marketplace markup. The second happens when you spend a card denominated in one currency on a booking priced in another: the travel brand or the card issuer converts at their own rate, typically 2–3% worse than the interbank rate.
Buy 200 USD of credit, book a hotel priced in euros, and you have paid a marketplace markup and an FX spread on the same money. Buying credit denominated in the currency you will actually be billed in removes the second one entirely, and it costs nothing to get right.
Airline credit adds a further wrinkle: it is generally tied to the airline’s country of issue, so a US carrier’s credit may only be usable on US-billed bookings even when the airline flies from everywhere.
When a prepaid card wins
Putting it together, brand credit makes sense in a narrow set of cases and a prepaid card makes sense in most of the rest.
Brand credit works when
- You fly one airline repeatedly and know you will use it
- The booking is non-refundable anyway
- There is a genuine seasonal promotion on the credit itself
- Airbnb, where credit applies automatically and cleanly
Prepaid card works when
- Dates or destination might change
- You will comparison-shop across several sites
- The booking currency differs from your credit
- You want a refund you can still spend elsewhere
The mistake we watched somebody make
A colleague bought $600 of airline credit with crypto for a trip that later moved by two months. The airline refunded correctly and promptly — as credit, with a twelve-month expiry, on a carrier that does not serve their new route.
The money still exists. It is just now a problem to be solved rather than money. A prepaid card would have cost a percentage point more and avoided the whole situation.
