Discover the best travel tips for navigating Chicago O’Hare International Airport (ORD) smoothly. From terminal transfers and security advice to transport hacks, lounge access, and hidden airport features, these practical tips will help you save time and reduce stress during your trip.
Pro Tip: O’Hare is one of the busiest airports in the world. Even experienced travelers should allow extra time for transfers, security checks, and walking distances.
Terminal & Connection Tips
Know your terminal before arriving
O’Hare has four operating passenger terminals. Terminal 5 handles most international flights, while Terminals 1 and 3 are dominated by United and American Airlines operations. Always confirm your terminal before leaving for the airport.
Use the ATS train for fast terminal transfers
The Airport Transit System (ATS) operates 24/7 and connects terminals, parking lots, rental cars, and train stations. It is usually the fastest way to move around the airport complex.
Some terminal walks are surprisingly long
Certain gates at O’Hare require lengthy walks after security. International gates at Terminal 5 and some concourses in Terminal 1 can take considerably longer than expected.
Connection Tip: International transfers at Terminal 5 may require extra time due to immigration, customs, and terminal transportation.
Security & Check-In Tips
Morning security lines can be extremely busy
The busiest period at ORD is usually early morning. If flying between 5 AM and 9 AM, arrive earlier than normal to avoid missing your flight.
TSA PreCheck can save significant time
TSA PreCheck lanes are available at several checkpoints and can dramatically reduce waiting times during peak periods.
Check your gate before stopping for food
Some concourses are very large. Always verify your gate location before sitting down at a restaurant or coffee shop.
Transport & Arrival Tips
The CTA Blue Line is the cheapest way downtown
Chicago’s Blue Line train connects O’Hare directly with downtown Chicago 24 hours a day and avoids heavy road traffic.
Traffic around O’Hare can be intense
Road congestion near the terminals can become severe during rush hours. Consider using train transport when possible.
Ride-share pickups are not directly outside every terminal
Uber and Lyft pickup areas vary depending on the terminal and may require short walks or using designated pickup zones.
Smart Move: If carrying lots of luggage or traveling with children, pre-booking a private transfer can save time and stress.
Services & Comfort Tips
Use airport lounges during long layovers
O’Hare offers multiple airline lounges and premium waiting areas with food, drinks, showers, Wi-Fi, and quieter seating areas.
Bring a portable charger
Although charging stations are available throughout the airport, many seats near gates become occupied quickly during busy periods.
Explore the airport art installations
O’Hare features famous public art displays including the iconic neon tunnel connecting concourses in Terminal 1.
Wi-Fi is free and unlimited
Free Wi-Fi is available across all terminals, gates, lounges, restaurants, and public airport areas.
Baggage & Practical Tips
Label your luggage clearly
With millions of passengers every year, baggage mix-ups can happen. Add a visible luggage tag and contact details to your suitcase.
Lost items depend on where you misplaced them
Items lost on aircraft are handled by airlines, while public-area items are managed separately by airport authorities or TSA depending on the location.
There are no traditional luggage lockers
O’Hare does not currently offer standard public baggage lockers inside terminals, so plan accordingly during long layovers.
