Public Transportation from O'Hare Airport (ORD)

O'Hare Airport is well connected to Chicago and its suburbs through a public transportation network that includes the CTA 'L' train, the Metra commuter train, and Pace buses. These are generally the most affordable options to get around. This guide offers an honest overview of each service, based on traveler experiences, to help you choose the best option for your needs and luggage.
Quick Questions About Public Transport at O'Hare
- What's the most popular and cheapest option to get downtown? The CTA Blue Line train. It operates 24/7 and takes you directly to downtown Chicago (The Loop) for about $5.
- What should I be aware of with the CTA Blue Line? It can get very crowded during rush hours, making it hard to travel with lots of luggage. Also, the walk from the terminals to the station can be long.
- Is there another train option? Yes, the Metra North Central Service commuter train. It’s a good alternative for getting to the northern suburbs, but only runs Monday through Friday.
- What about buses? The Pace Bus service (routes 250 and 330) connects the airport with various suburbs and other transit lines. Their stops are located at the Multi-Modal Facility (MMF).
CTA 'L' - Blue Line

Trains in Chicago are known as the "L", and the Blue Line is the most direct and affordable way to reach downtown Chicago from O'Hare.
User Experience
The CTA Blue Line is by far the most recommended option by travelers for its unbeatable cost-benefit ratio. Its direct connection to the city center and 24/7 operation are its biggest strengths. However, reviews highlight two key issues:
- Crowding: During rush hours or major events, trains can become completely full, making the ride uncomfortable if you're carrying multiple bags.
- Long Walks: The 'L' station is located on the lower level of the main parking garage, and reaching it from your terminal (especially Terminal 5) requires a significant walk.
Tip: It's the perfect choice if you're traveling light and your destination is near a Blue Line stop. If you have a lot of luggage or are traveling during rush hour, consider comfort versus cost.

The trip from O'Hare to downtown (The Loop) takes about 45 minutes.
