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 ABE handles — which airlines fly from it, the gate range, and key amenities to know before you go.
ABE's single Main Terminal handles all check-in, ticketing, baggage claim, and the airport's one security checkpoint. Pre-security you'll find the Lehigh Valley Cafe (Level 2), the Passenger Services Desk, ATMs, a book exchange, and family/lactation rooms on the lower and second levels. From the checkpoint, passengers walk through an underground pedestrian tunnel to the satellite Gate Concourse building — there are no gates in the Main Terminal itself.
A satellite building dedicated November 14, 1997, connected to the Main Terminal by an underground tunnel. It holds all 9 of ABE's passenger gates along with the airport's post-security dining and retail: The Drafthouse @ABE, Which Wich, Dunkin', Zekraft, Avenue C Market, and Market in the Valley. It also houses the Tech Bar charging station and children's play area, the sensory room (lower level), and a service-animal relief area near Gate 14. Allegiant, American, Delta, and United all depart from this single concourse.
Underground pedestrian tunnel between the Main Terminal (ticketing, check-in, security) and the satellite Wiley Post Jr. Gate Concourse — no train, tram, or airside bus; it's a short, fully enclosed walk.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at ABE — 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.
ABE is compact and single-checkpoint, so wayfinding is simple — clear security in the Main Terminal, then follow signs to the underground tunnel that leads directly to the Gate Concourse and all 9 gates. Budget only a few extra minutes for the tunnel walk, even with a stroller or luggage cart.
