If you are flying to you will get in at either one of the Chicago Airports (O’Hare or Midway), or Indianapolis. O’Hare (ORD) and Indianapolis (IND) offer direct shuttle bus connections to Purdue Campus, the by far easiest way to get from either airport to Purdue.
There is no direct shuttle route from Purdue University to Chicago Midway Airport. You need to either take public transportation to Chicago O’Hare Airport for the shuttle ride to Purdue University or to use a car rental service at the airport.
