AD PLACEMENT — CONTEXTUAL
IND's single-terminal design means you never need a train or long shuttle ride between gates.
If connecting to one of the rare international flights, allow extra time for the federal inspection facility, especially on flights from Mexico or the Caribbean.
Security lines are usually short outside of early morning and early evening banks, so most connections can be made comfortably.
The central hall has ample food options, making it easy to grab something between flights without a long walk.
Since IND isn't a hub for any carrier, gate agents are less experienced with tight rebooking rushes, so head straight to a service desk if you're worried about missing your flight.

Low risk
Moderate
High risk
Tight connections are safer outside peak hours. Morning rush (6–9a), midday (11a–2p), and evening (4–8p) are highest risk.
The Colonel H. Weir Cook Terminal has a single central hall with two concourses branching off it, so passengers simply walk between gates with no train or shuttle required. There is one central security checkpoint, and international arrivals (limited seasonal service) clear through a small federal inspection area before reaching the sterile side.
