Incheon Airport Currency Exchange: Counters, Rates, Hours

Landing at Incheon with no won in your pocket is fine. The airport is built for exactly that. What trips people up is picking the wrong counter, or assuming every window is open at 2am on a holiday weekend when it isn't.

Where the counters actually sit, by terminal

Both Terminal 1 and Terminal 2 use the same basic layout. Exchange windows cluster in the arrival hall on the 1st floor, right where you walk out after immigration and baggage claim, and again in the departure hall on the 3rd floor near the check-in islands. T1's arrival-floor counters sit near the customs exit, a short walk before the doors to the transportation center. T2's sit in a similar spot, close to the main arrival meeting area. Exit numbers do get renumbered occasionally as the terminals adjust signage, so treat the overhead directory boards on the day as the final word rather than any exit number written here.

You don't need to hunt. If you've cleared immigration and baggage claim, a counter is within sight before you reach the exit doors. You'll see branded windows for Korea's major banks, KEB Hana Bank (하나은행), Woori Bank (우리은행), Shinhan Bank (신한은행), and KB Kookmin, alongside a few independent money-changer kiosks. The departure-side counters exist mainly for people topping up won before flying out, or converting leftover cash back to dollars or yen.

If you're unsure which terminal your flight uses, sort that out first. See Incheon Airport Terminal 1 vs Terminal 2 before you leave home. T1 and T2 sit several kilometers apart, and the exchange counters don't overlap between them.

How airport rates compare to city exchanges

Airport counters run on the same base interbank rate as everywhere else in Korea. What differs is the spread: the margin the counter adds when it buys or sells cash. Rent at an international airport is high. That gets baked into the rate you're offered at the window. Private money changers clustered around Myeongdong (명동) typically post a tighter spread on major currencies like USD, JPY, and CNY than a bank counter at Incheon does.

The base won-dollar rate itself isn't fixed. It moves with global markets and trade flows, and over the past year it has drifted anywhere from the mid-1,300s to higher levels per dollar depending on the month. Whatever the headline rate is the day you land matters less than the spread you're charged on top of it. On a busy travel week, spreads at both airport and city counters can widen further. As a rule of thumb, exchanging a large sum at the airport instead of in the city can cost you noticeably more in fees over, say, a $500-1,000 conversion.

The practical fix: change a small amount at the airport, enough for a taxi or an AREX ticket, a T-money top-up, and a meal, then do your main exchange once you're in the city. For a fuller breakdown of paying with cards versus cash in Korea generally, see How to Pay in Korea as a Tourist.

That third row matters. Major Korean banks let you reserve a rate through their app or website before you fly, then collect the cash at an airport counter on arrival, sometimes with a small discount on the standard airport spread. It takes a few minutes and locks in a rate closer to what you'd get in the city, without the detour to Myeongdong on day one.

Late-night and early-morning arrivals

Incheon Airport itself never closes. Flights land past midnight and before dawn, especially long-haul arrivals from the US and Europe. According to the official Visit Korea currency guide, standard exchange hours run roughly 06:00 to 22:00, though some counters at Incheon do operate around the clock. In practice this means a handful of windows per terminal, usually the ones nearest the arrival hall, keep extended or 24-hour schedules while smaller kiosks and most departure-hall branches close by evening.

If your flight lands at 1am, don't assume every counter is lit up. Walk the arrival hall rather than heading straight for the first shuttered window. A currency exchange counter that closes at 9pm or 10pm can sit a few meters from one that never does. Hours get adjusted terminal by terminal without much public notice, so check the airport's official exchange page or the operating bank's own listing before relying on a specific window at an odd hour.

If everything nearby is dark, a foreign-card-friendly ATM is the fallback, though it charges its own conversion fee. Some travelers also use the multi-currency cash kiosks near the transportation level, which double as a prepaid transit card. Getting online matters here too: grab a Korea eSIM before you land so you can check counter hours, map the terminal, or call a taxi the moment you clear immigration, instead of hunting for airport wifi at 2am.

Public holidays: Seollal and Chuseok

City bank branches close on Seollal (설날, Lunar New Year) and Chuseok (추석), Korea's two big holiday periods. Incheon Airport does not. Departures don't pause for the holidays. If anything, they spike: the airport corporation's own pre-departure passenger forecasts for this year's Chuseok put outbound travelers across the three busiest travel days at roughly 320,000 across both terminals combined. With that many people flying, the airport keeps a working roster of exchange counters open through the holiday, though not every branded window will be staffed and hours can shift to match flight schedules rather than a normal weekday timetable.

Don't count on a specific counter being open on Seollal or Chuseok just because it usually is. Confirm on the airport's official site or by phone if you're arriving mid-holiday and need cash on the spot. If you're heading further than Seoul once you land, plan the onward leg too. Options like the direct bus to Daejeon, Cheongju and Eumseong or a private airport transfer run on holiday schedules of their own.

What to actually do with your cash

Exchange enough at the airport to get to your accommodation and cover the first day: transport, a meal, maybe a coffee. Save the bulk of your exchange for Myeongdong or another city cluster once rates settle during business hours. Keep the exchange receipt if you plan to convert leftover won back before flying home. Some counters ask for it.
