You can easily bring your bicycle to or from both Chicago airports by using the Chicago Transit Authority (CTA). CTA's Blue Line goes directly to O'Hare Airport; the Orange Line goes directly to Midway Airport. For more information about biking to the airports, visit the Bike to the Airport site.
Bicycles are permitted on trains every weekday except from 7 AM to 9 AM and 4 PM to 6 PM. On Saturdays, Sundays and holidays, bicyles are allowed on trains all day. If you board the train with your bicycle before the hours listed above and your trip extends into those hours, the CTA allows you to finish your trip. If trains are crowded, the use of trains by cyclists may be restricted by the train operator as appropriate. Find the latest information about CTA's Bike & Ride program.
