Currency and Payments at ORD
The official currency of the United States is the U.S. Dollar (USD). While credit and debit cards are overwhelmingly the preferred method of payment across Chicago and at ORD, it's always wise to carry a small amount of cash for tips, vending machines, or smaller, independent shops.
ATMs are widely available and conveniently located throughout all ORD terminals in both the landside and airside areas, typically offering more favorable exchange rates than dedicated currency exchange counters. Services like Travelex operate counters within the arrivals and departure halls of Terminal 5 (International) and other terminals. Contactless payment methods (such as tap-to-pay cards or mobile wallets) are widely accepted and encouraged throughout the airport and city for both convenience and speed. We recommend using a travel-friendly card or app-based wallet to minimize foreign transaction fees and enhance security.
Chicago O'Hare (ORD) Airport Basics
Chicago O'Hare International Airport (ORD) is one of the world's busiest airports and North America’s central international gateway. ORD features a sprawling complex with four main passenger terminals: Terminal 1 (primarily home to United Airlines and Star Alliance partners), Terminal 2 (serving various domestic carriers and Air Canada), Terminal 3 (the main hub for American Airlines and Oneworld partners), and Terminal 5 (the dedicated International Terminal for most non-U.S. carriers).
The airport is exceptionally well-signed, with modern amenities like free Wi-Fi, extensive charging stations, and helpful traveler assistance points located throughout. Flight check-ins and TSA security areas are highly organized but will certainly get crowded during peak hours. Always allow generous extra time for security screening and walking between distant gates, especially if you have a tight connection requiring an Airport Transit System (ATS) ride between terminals.
ORD Security & Customs Fast Track
Chicago O'Hare (ORD) enforces strict TSA rules, requiring liquids to follow the 3-1-1 rule. Security lines can be long, so plan to arrive 3 hours before international flights and 2 hours domestic. Use TSA PreCheck or Global Entry to expedite screening. For international arrivals at Terminal 5, you’ll clear U.S. Customs and Border Protection (CBP). For departures, expect TSA screening and airline document checks. Always have your documents ready to ensure a quick, stress-free experience.
