A convenient option is to fly to the Indianapolis International Airport and take a shuttle bus straight to the Purdue Union Hotel. The shuttle departs every two hours and it takes about 70-minutes. To make a shuttle reservation (not necessairy but preferable) or to check out the shuttle schedule, go to the LafayetteLimo web page. Instead of taking a shuttle, you can also rent a car and drive to Purdue from the Indy airport, it takes about 65-minutes.

Another option is to fly into Chicago, then either rent a car and drive (about 2 to 2.5 hours) to Purdue, or take a shuttle (four daily departures) from Chicago O'Hare Airport to Purdue. See the Express Air Coach web page for schedule and reservation detail.
