Maps are updated when terminals are renovated or new concourses open. Terminal 5 at LAX, for example, has been closed since October 2025 for reconstruction — always confirm your terminal from your boarding pass rather than relying on a saved map.
Here is what each terminal or concourse at IND handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Gates A2–A25 (20 gates). Serves Air Canada, Delta, American, Alaska, Spirit, Frontier, and United. All international arrivals are processed here. Checkpoint A is the only PreCheck-equipped checkpoint. CLEAR works with PreCheck at Checkpoint A for the fastest combination.
Gates B3–B25 (19 gates). Serves Southwest, American, Alaska, and Allegiant. Domestic-only low-cost and Southwest operations. Checkpoint B has standard lanes only — no PreCheck. Connects airside to Concourse A via the central Civic Plaza walkway without re-screening.
Internal walkway via the central Civic Plaza — no train or shuttle needed. Concourses A and B connect post-security; switching between them does not require re-clearing security.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at IND — wait times for people-movers, buses, or security re-screening add up faster than the physical distance suggests. Build the buffer into your Leave-By time, not your gate arrival time.
TSA PreCheck is available only at Checkpoint A — if enrolled, always use Checkpoint A regardless of which concourse your gate is on, then walk airside to Concourse B if needed. There is no re-screening penalty for entering via Checkpoint A and walking over. Standard peak waits average 20–30 minutes; PreCheck at Checkpoint A averages 4 minutes.
