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 rail, and Pace buses. These options are generally the most economical way to get around. This guide offers an honest perspective on each service, based on traveler experiences, so you can choose the option that best suits your needs and luggage.

Quick Questions about Public Transportation at O'Hare

What is the most popular and economical option to get downtown? The CTA Blue Line train. It runs 24/7 and takes you directly to downtown Chicago (The Loop) for about 5 USD.
What should I keep in mind with the CTA Blue Line? It can be very crowded during peak hours, which makes traveling with a lot of luggage difficult. Additionally, the walk from the terminals to the station can be long.
Is there another train option? Yes, the Metra commuter rail (North Central Service). It's a good alternative for going to the northern suburbs, but it only operates Monday through Friday — and it's a good idea to confirm the service status before heading to the station.
What about buses? The Pace Bus service (routes 250 and 330) connects the airport to several suburbs and other transit lines. Their stops are at the Multi-Modal Facility (MMF).
Can I rely on Metra or Pace if my schedule is tight? It's not ideal. Both services accumulate reviews with reports of delays, cancellations, or buses that don't show up. If your connection depends on an exact schedule, the CTA Blue Line train or a private transfer are more predictable options.

Overview: How Reliable is Each Option

Before choosing, it's worth understanding that the three public transportation options are not equally predictable. Here's what the most recent reviews of each one show.

The Train, the Most Reliable Option

User experience:

The CTA Blue Line is, by far, the most recommended option by travelers. One important clarification: the strongest complaints about the CTA network in general — buses that appear on the app and then disappear without notice, dirty vehicles, drivers who don't enforce rules — are concentrated on the city bus lines, not on the train service to the airport. For the specific train to O'Hare, the reported experience is consistently more positive.

Strategy: if your priority is to arrive at a fixed time (for example, to catch another flight or a booked tour), the train is the safest public transportation option of the three.

Metra: Reliable on Paper, Less So in Practice

User experience:

Reviews of Metra in general are systematically more critical than those of the CTA train: almost daily delays without clear explanation, frequent cancellations, trains that leave earlier than scheduled without notice, and poor communication during incidents. Travelers also point out that there are no refunds or discounts for delays. This doesn't mean the service doesn't work most of the time, but it does mean you should allow a safety margin if you use it to catch a flight.

Strategy: don't rely on Metra if your connection is tight, and check the service status on the Metra app before heading to the station.

Pace: the Least Recommended Option

User experience:

Of the three options, Pace has the most negative review profile: buses that don't show up despite being scheduled, schedules that in practice aren't met, and drivers who sometimes ignore stops or stop in incorrect places. There are documented cases of passengers left stranded waiting at their stop with the bus never arriving. In general, it's recommended to consider it only when there's no other reasonable alternative for your destination.

Strategy: if you depend on Pace to get to an important commitment, always have an alternative plan (taxi or rideshare) ready in case the bus doesn't show up at the expected time.

CTA 'L' - Blue Line

AI-generated image

Trains in Chicago are known as the "L," and the Blue Line is the most direct and economical way to get to downtown Chicago from O'Hare.

User experience:

The CTA Blue Line is, without a doubt, the most recommended option by travelers for its unbeatable value for money. The direct connection to downtown and its 24/7 operation are its greatest strengths. However, reviews warn of two key points:

Crowding: During peak hours or major events, trains can become completely full, making the journey uncomfortable if you have several suitcases.
Long Walks: The 'L' station is located on the lower level of the main parking garage, and getting there from your terminal (especially Terminal 5) requires a considerable walk.

Tip: It's the perfect option 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 peak hours, consider comfort versus cost.

Travel time and fare

The journey from O'Hare Airport to downtown (The Loop) takes approximately 45 minutes.

A regular ticket from the airport costs 5.00 USD. You can purchase it at the station's vending machines with cash or credit card. You can also use a rechargeable Ventra card or contactless payment methods.

To see the most up-to-date schedules and hours, visit the official CTA website.

Pickup location

The station is located on the lower level of the main parking garage for Terminals 1, 2, and 3.

From Terminals 1, 2, and 3, follow the "CTA Trains" or "Trains to City" signs through the lower-level pedestrian tunnels. From Terminal 5, you must first take the free Airport Transit System (ATS) train to the Terminal 3 station and from there follow the signs.

Metra Commuter Rail

Metra offers commuter rail service connecting downtown with the suburbs. The line serving O'Hare is the North Central Service, which runs from Union Station to Antioch.

Important: This service only operates Monday through Friday during morning and afternoon peak hours. It is not an option for weekends or night travel.

User experience:

Reviews of this service are mostly critical regarding punctuality: frequent delays without explanation, cancellations, and in some cases, early departures compared to the published schedule, with no prior notice. Several travelers who depend on this train to get to work mention having opted for other lines or means of transportation for this reason. There are no refunds or discounts applicable for delays.

Strategy: if your schedule is tight, confirm the service status on the Ventra app before heading to the station, and have the CTA Blue Line or a private transfer as a backup.

Travel time and fare

The journey from O'Hare Transfer Station to Union Station downtown takes about 30 minutes.

Tickets can be purchased on board or through the Ventra app. The fare to Union Station is approximately 6.25 USD.

Pickup location

The O'Hare Transfer Station is located next to the Multi-Modal Facility (MMF).

From any terminal, take the free ATS train to the MMF stop. The Metra station is located at the northeast corner of the building. For more information and schedules, check the Metra website.

Pace Buses

Pace is the suburban bus service that connects O'Hare with areas not covered by the 'L' train.

User experience:

Of the three public transportation options in this guide, Pace consistently receives the most negative reviews: buses that don't show up at the scheduled time, and reports of drivers who ignore stops or stop in incorrect places. There are documented cases of passengers — including people with special needs — who were left waiting at their stop without the service arriving. The general recommendation in reviews is to use it only when no reasonable alternative is available.

Strategy: if your destination is only covered by Pace, leave with plenty of time and confirm the route status on the Ventra app before heading to the stop.

Route 250

This route offers daily service and connects to key points such as the CTA Davis Street station (Purple Line), the CTA Skokie station (Yellow Line), and Lutheran General Hospital. The trip to Davis Street station takes approximately 65 minutes.

Route 330

This route operates Monday through Saturday and connects to locations such as La Grange, Countryside, and Hodgkins. The trip to Archer/Harlem takes approximately 80 minutes.

Fares

A single ride costs 2.00 USD with a Ventra card or contactless payment, and 2.25 USD if paying in cash (exact fare required).

Pickup location

Pace bus stops are located at the Multi-Modal Facility (MMF) bus terminal, at platforms 8 and 9. To get there, take the free ATS train from any terminal to the MMF stop.
