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 MDT handles — which airlines fly from it, the gate range, and key amenities to know before you go.
The smallest of MDT's three concourses, with gates A1 and A3 active (A2 is currently unused), served by Delta Air Lines. Phillips Seafood, the airport's only full-service sit-down restaurant, is near gate A1, and the Susquehanna Club frequent-flyer lounge sits across from gate A2.
MDT's largest concourse, with gates B1, B2, B3, and B6 active (B4 and B5 are currently unused), served by United Airlines (B1, B3), American Airlines (B2), and Allegiant Air (B6). This concourse holds most of the terminal's retail and dining — Starbucks, Capital Café, the Perfectly Pennsylvania gift shop, and Hudson News.
A three-gate concourse (C1–C3) served by American Airlines, home to Auntie Anne's Pretzels, Dunkin', Crafted (a local-beverage bar), and The Great American Bagel Bakery.
MDT is a single, compact terminal (opened 2004) built in a pier finger layout near the middle of the airfield — there is no train or tram. Ticketing and baggage claim are on the first floor, passenger pickup/meeting areas are on the second floor, and the three gate concourses (A, B, C) branch off the third-floor departure level past the security checkpoints; every gate is reachable on foot within a few minutes.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at MDT — 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 MDT is one small terminal rather than a sprawling hub, orient yourself by floor and concourse letter rather than looking for a shuttle: first floor for ticketing/bags, second floor for pickup, and up through security on the third floor for gates A, B, and C. Most dining and both retail shops are concentrated in Concourse B, so if you have extra time before boarding from A or C, walk over to B.
A few habits that prevent last-minute sprints:
Experienced travellers at MDT use a short checklist every time:

Open your airline app about two hours before departure — gate assignments sometimes change after check-in closes. Look for departure boards throughout the terminal for real-time gate information.
