O'Hare International Airport
ORD is one of the busiest airports in the world. It is a hub for American and United Airlines. It is also served by many international carriers.
An automated Airport Transit System (ATS) train provides internal transportation between airport terminals and long term (economy) parking areas.
The main 'L' stop, O'Hare Station, is located by the main parking garage located outside of Terminals 1, 2, and 3. Pedestrian tunnels link between the terminals and this station. The Blue Line links the airport with the Chicago Loop and operates 24 hours a day. Trains run every 3-8 minutes on weekdays during peak hours and every 7-10 minutes midday and evening.
To reach to/from Terminal 5 (most international carriers and all international arrivals except from Canada), take the ATS between terminal 3 and 5.
Metra's North Central Service provides connection to/from O'Hare at the O'Hare Transfer Station. To get to the airport terminals to Metra, take the ATS train from the terminals to Economy Lot E, and transfer to a shuttle bus from Lot E to the train station. To get from the Metra stop to the terminals, take a shuttle bus from the train station to Lot E ATS station and transfer to the ATS to get to the terminals.
The North Central Service mostly runs during weekday peak hours with very limited midday and reverse commute service.
Pace buses provide connection from other Metra lines in the suburbs to Lot E ATS station. The CTA Blue Line connects with other Metra lines at Jefferson Park Transit Center and in the Chicago Loop.
