Money & travel
Skip the exchange booth at Ellison Onizuka Kona International Airport at Keahole. Use an ATM with a no-fee card — the ATM gives you the real mid-market rate, while airport exchange booths charge 10–20% above it. On a $500 exchange, that difference is $50–100 in hidden costs.
The key rule
Airport currency exchange booths typically charge 10–20% above the mid-market rate.
On a $500 exchange, that is $50–100 in hidden fees. The ATM is almost always better — even with a bank fee. And with a no-fee card, the ATM is unambiguously better.
None — despite genuine scheduled international service (Japan Airlines to Tokyo, plus seasonal Air Canada/WestJet flights to Vancouver and Calgary) processed through KOA's dedicated Federal Inspection Service (FIS) facility, the airport has no currency exchange counter, kiosk, or Travelex-style booth anywhere in the terminal or the International Arrivals Building.
There's no in-terminal exchange markup to worry about because there's no booth at all — but that also means travelers arriving with yen or Canadian dollars have no way to convert cash on-site before leaving the airport.
ATMs are available in the terminal per the airport's official Banks & ATMs page, though exact machine locations and operating banks are not published in detail; expect them near baggage claim and the main ticket lobby areas of Terminal 1 and Terminal 2.
Airport ATMs dispense US dollars only, on standard nationwide networks (Visa/Plus, Mastercard/Cirrus, STAR). Using a no-foreign-transaction-fee card (Schwab, Wise, or Revolut) avoids extra charges when withdrawing.
Best cards for ATM use abroad
Recommended for KOA
Exchange currency before you fly to KOA — arriving international travelers should convert cash at their origin airport (Narita/Haneda, Vancouver, or Calgary) or at a bank in Kailua-Kona town, since KOA itself has zero currency-exchange infrastructure despite handling real international flights.
Pro Tip
If you're connecting through Honolulu (HNL) on the way to KOA, that's your best chance to exchange money or use a full-service exchange counter — HNL has proper international-arrivals currency facilities that KOA, despite its own Federal Inspection Station, does not replicate.
Before you leave
Order foreign currency from your bank before departure — Chase, Bank of America, and Wells Fargo all offer currency ordering at branches and online (3–7 business days). Rates are better than airport booths, and you avoid the airport rush entirely.
At your destination
Withdraw from a local ATM at your destination — you get the real mid-market exchange rate, minus a small network fee. A no-fee card eliminates even that. This is almost always the cheapest option.
In transit
Currency exchange at city banks or post offices in your destination country is typically far better than airport rates in both countries. Most major cities have walk-in currency exchange with rates 5–10% better than airport booths.
Is it better to exchange currency at KOA airport or at my destination?
Almost always at your destination. Airport exchange booths at Ellison Onizuka Kona International Airport at Keahole charge 10-20% above the mid-market rate. At your destination, ATMs give the real interbank rate minus a small network fee — typically saving $50-100 on a $500 exchange versus the airport booth.

What is the best card to use for foreign currency at KOA?
The Charles Schwab debit card is the top choice — it reimburses all ATM fees worldwide and charges 0% on international transactions, giving you the real mid-market exchange rate. Wise and Revolut travel cards are strong alternatives with similar 0% fee structures. Avoid using a standard bank debit card, which typically charges 1-3% foreign transaction fee plus an ATM surcharge of $3-5.
