Indianapolis Airport has one terminal with two levels and Concourses A, B/C and D, which lead to the departure gates. On the Upper Level, all passengers with tickets and boarding cards must pass through the security screening checkpoints found at all entrances.

The Concourses have telephones, Internet access, restaurants, retail shops and additional services comparable to most international airports. The Lower Level includes baggage claims and a U.S. Postal Center. Outside this level, passengers will find taxi stands, bus stops and shuttle buses. The walkways to the parking garage are in the area outside the terminal.

The Ground Transportation Center is located in the lower level of the parking garage, opposite the passenger terminal. Here passengers can rent cars, hire a taxi or limousine or take a shuttle bus heading to nearby cities. Hotel courtesy vehicles and city bus service are also available. Passengers with questions may call 319-487-5217

Indianapolis Airport has curbside check-in for departing passengers. Drivers drop-off passengers in front of the airline for check-in, but must remain in the vehicle. Parking for 30 minutes or less in the parking garage is free. Short-term parking is available on the surface lot across from the parking garage. Only passengers with tickets and boarding passes may go beyond the security checkpoints. Assistance for special needs passengers is always available.

The status link for arrivals and departures on the IND airport website may not always provide accurate information, so the airport recommends contacting the appropriate airlines.
