For those flying, Chicago has two airports:

• O'Hare International Airport
• Midway International Airport

Both are approximately the same distance from downtown Chicago, and both are connected to downtown via inexpensive public transportation ($2 each way). From O'Hare, take the Blue Line and get off at the Jackson station; this station is 2 blocks west of the DePaul Center. From Midway, take the Orange Line and get off at the Library station (on some maps, this station may be called Library/State). This station is 1/2 block west of the DePaul Center. Here is a Chicago Transit Authority system map.

If you are driving, here are directions to DePaul's Loop campus once you get to the Chicago area.
