University faculty and staff who regularly travel by air are invited to participate in a study about airport choice in the Chicago region. What factors influence your choice of airport when you fly, and does your choice differ for personal or business travel? Participants will be interviewed for twenty to thirty minutes on their travel choices. Any responses you give will remain confidential, and all participation is strictly voluntary. If you are interested, contact Julie Cidell, Department of Geography, University of Illinois, at email@example.com or 217-244-4665.
