Where to find ATMs and currency exchange across O’Hare’s Terminals 1, 2, 3 and 5, which option gives the best rate, and how much US cash you actually need on arrival.

Terminal financial overview

Chicago O’Hare is one of the busiest airports in the world, with four passenger terminals (1, 2, 3 and the international Terminal 5) linked airside and by the Airport Transit System. Getting cash is straightforward, but as almost everywhere, an ATM withdrawal in US dollars beats the exchange counters for all but small amounts. This guide shows where the machines and Seaway Bank exchange counters sit, how to avoid markups, and how to pay your way into the city.

O’Hare has four passenger terminals, numbered 1, 2, 3 and 5 (there is no Terminal 4). Terminals 1–3 form the domestic core and are connected airside; Terminal 5 handles most international flights and is reached landside by the free Airport Transit System.

If you land internationally you will usually arrive at Terminal 5, which has both ATMs and an exchange counter in the arrivals flow. For domestic flights and connections, Terminals 1 to 3 all have ATMs and Seaway Bank desks, and the airside connectors make it easy to reach a machine. When a particular counter is closed, another terminal’s desk is a short transit ride away.

Across 4 terminals, this page lists 8 ATM locations (4 airside, 4 landside) and 4 exchange counter, kiosk or machines (3 airside, 1 landside). Terminal 5 has the widest choice.

• Terminal 5: Most international arrivals and departures. 2 ATM locations, 1 exchange point.
• Terminal 1: United and partners. 2 ATM locations, 1 exchange point.
• Terminal 2: Several domestic airlines. 2 ATM locations, 1 exchange point.
• Terminal 3: American Airlines and partners. 2 ATM locations, 1 exchange point.

Inside vs. outside security strategy

For the best value, skip the exchange counter and withdraw US dollars from a bank ATM, choosing to be charged in USD rather than your home currency. If you are connecting internationally and cannot leave airside, the ATMs inside security will cover you. If you have cleared customs in Terminal 5, use an arrivals-area ATM before heading to ground transport. Keep the Seaway Bank counters for the cases where you need another currency quickly or your card is not working.

As a rule at ORD: withdraw USD from a bank ATM landside when you arrive, buy only small amounts at a counter, and sell leftover US dollars back before security when you leave. Airside counters exist for convenience, not value, and once you are through passport control you cannot walk back out to compare.

Avoiding Dynamic Currency Conversion (DCC) markups

Dynamic Currency Conversion is the offer to charge a foreign card in its home currency instead of USD. It looks helpful because you see a familiar number, but the ATM or shop sets the exchange rate, and it is usually several percent worse than the rate Visa or Mastercard would apply. Airports are where most travellers meet it first.

Whenever an airport ATM or a card terminal offers to charge you in your home currency instead of US dollars, decline it and choose US dollars. That “convenience” option, called Dynamic Currency Conversion, lets the machine set its own exchange rate, which is typically 3–7% worse than the rate your own bank or card network would use. Paying in the local currency always routes the conversion through your card network (Visa, Mastercard), which is almost always cheaper.

1. At an ATM, when the screen asks to convert or offers a "guaranteed rate", choose decline or without conversion.
2. At a card terminal, if asked "USD or your currency?", pick USD. If staff choose for you, ask them to redo it.
3. Read the operator fee on the ATM screen before you confirm. If it is high, cancel and try another bank's machine.
4. Check your receipt: a printed exchange rate or the word "DCC" means a conversion was applied.

Local cash vs. card tips for Chicago

You need very little cash in Chicago. Cards and mobile wallets work for the CTA, taxis, ride-hailing and almost all shops and restaurants. Keep around $20–$40 in small bills for tips, the occasional cash-only spot and small incidentals. Tipping is customary in the US — about 15–20% in restaurants, a dollar or two per bag for porters, and 15–20% for taxi drivers — so small denominations are more useful than large notes.

Before you fly, check two things with your bank: the foreign transaction fee on card payments and the fee for overseas ATM withdrawals. A card that waives both makes paying in USD the cheapest way to spend in United States. Tell your bank you are travelling if it still asks, carry a backup card from a different network, and keep the airport counter for small top-ups only.

Prices and operators at airports change. We checked this page against the official O'Hare and operator listings on 20 October 2026; confirm hours on the airport's own map on the day you travel.
