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 ATW handles — which airlines fly from it, the gate range, and key amenities to know before you go.
ATW has one terminal building with a single concourse — there are no separate Terminal A/B or airside train connections to worry about. A multi-phase gate expansion that began in November 2023 added six new gates while retiring three older ones, bringing the concourse to 10 gates with jet bridges (Gates 3 through 8, including 7b, with jet bridge service; Gate 8b handles tarmac/walk-out boarding). The gates accommodate Embraer E-Jet, Boeing 737, and Airbus A320-family aircraft flown by American, Delta, United, Allegiant, and Sun Country. The single TSA security checkpoint sits centrally in the terminal, with gates fanning out to either side, so every gate is a short walk from screening.
Everything is on one level in one concourse — passengers simply walk from check-in, through the central security checkpoint, to their gate. There is no tram, train, or shuttle needed between gates; the whole terminal can be crossed on foot in a few minutes.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at ATW — 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.
Because ATW is a single small concourse, arrive with the standard airline-recommended buffer (about 90 minutes before departure) rather than padding extra time for long terminal walks — the walk from curb to any gate rarely takes more than 5–10 minutes even at the far ends of the 2023-expanded gate area.
A few habits that prevent last-minute sprints:

Look for departure boards throughout the terminal for real-time gate information.
