For many locations, including downtown Chicago, it is convenient to use the rail lines, sometimes called the EL for elevated, to get to and from the airport. Oneway adult fare is $2.25 but ticket machines do not give change. The stations are right in the airport basement, so one does not go outside except for the international terminal at ORD. An important trick is to check whether your destination and transfer stations are designated as handicapped accessible on the route map. (For example, from MDW to some destinations in the loop, get off at Clark and Lake and walk a couple extra blocks rather than State and Lake, which is the end of the ORD line.) Otherwise you may be forced to carry luggage up and down stairs. Some escalators are too narrow for certain wheeled bags, so be careful that your luggage does not get caught. Wider entry and exit turnstiles are available, so look for them. The Orange Line serves MDW, roughly thirty minutes from State and Lake. the Blue Line goes to ORD, 46 minutes from Clark and Lake.
