Airport exchange counters sell one thing: convenience at the moment you have the fewest alternatives. They're rarely a scam — they're just priced for a captive audience.
What the numbers say
NerdWallet's September 2026 update says:
- airport exchanges commonly charge around 14% above the IMF reference rate
- some premiums it found were above 17%
- Bank of America averaged roughly 6%, less than half the airport premium
On US$500, a 14% premium costs about US$70 before any fees. A no-foreign-fee card at the mid-market rate costs close to nothing.
Why the rates are usually worse
- Location costs: airport rents are high, and that's recovered through the spread.
- Captive customers: you've just landed, you need a taxi, and there's one counter in sight.
- "No commission" signage: the cost is in the rate, not a fee.
"Buy back" and "sell" rates
Counters display two prices: the rate at which they sell you foreign currency and the rate at which they buy it back. The gap between them is their margin. A wide gap means you lose twice if you change money on the way out and back again.
When it still makes sense
- The destination is cash-heavy and you need money for transport immediately.
- ATMs at the airport are out of order or don't accept your card.
- You're exchanging a small amount — enough to get to your accommodation.
Better options on arrival
- An airport bank ATM, withdrawing in local currency and declining any conversion offer. Check the operator fee shown on screen before you confirm.
- A card or phone wallet for the taxi or train if accepted.
- Exchange a small amount, then use city exchange offices or ATMs once you can compare.
Before you fly: a 5-minute plan
- Check the mid-market rate and write it down.
- Know which card you'll use at the airport ATM and that international use is on.
- Save the route and price of your airport transfer, and whether it takes cards.
- If you must buy cash before you go, order it from your bank in advance. It's usually cheaper than buying at the departures counter.
