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.
What is in each Long Island terminal?
Here is what each terminal or concourse at ISP handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Main Terminal (pre-security)
ISP's single Main Terminal building holds all check-in counters, ticketing, baggage claim, and landside services. A Ground Transportation Center opened in 2022 consolidating rental car agencies just outside. Pre-security amenities include Great American Bagel and a Dunkin' near the entrance, a CNBC News Shop, and East End Getaway (a Long Island-themed gift boutique in the atrium). From ticketing, passengers walk directly to one of the terminal's TSA checkpoints.
Veterans Memorial Concourse / Concourse A (post-security)
The airport's main post-security concourse, renamed the Veterans Memorial Concourse in honor of Long Island's veteran community. It holds 9 gates (A1L, A1–A8) and serves Southwest, Frontier, JetBlue, Breeze, and Avelo. Amenities include Blue Point Brewing (Point Blue Pub & Provisions), a second Dunkin' location, Starbucks, Nathan's Famous in the food court, Paradies Gift Shops (across from Gate A5), an ATM (across from Dunkin'), a Mother's Room (near the East Checkpoint, across from Starbucks), a Service Animal Relief Area, water-bottle filling stations (between Gates A2–A3 and A6–A7), and USB-A/USB-C charging kiosks installed in 2023.
Concourse B (post-security)
A smaller two-gate concourse used by Cape Air's commuter turboprop flights to Boston. It connects to the same post-security corridor as the Veterans Memorial Concourse rather than requiring a separate walk or transfer.
How do I get between terminals at Long Island?
No train, tram, or shuttle bus is needed — ISP is a single-level walk-through airport. From the Main Terminal's ticket counters, passengers clear a TSA checkpoint directly into the Veterans Memorial Concourse (Concourse A); Concourse B's two Cape Air gates are a short walk further down the same post-security corridor.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at ISP — 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.
How do I find my gate at Long Island?
ISP is small enough to walk end-to-end in just a few minutes — once through the checkpoint you're immediately in the Veterans Memorial Concourse with every gate, restaurant, and shop within sight of each other. There's no long concourse trek or people-mover like at a major hub, so arrive with confidence that you won't need extra transit time inside the terminal.
A few habits that prevent last-minute sprints:
- Open your airline app two hours before departure. Gate assignments update in the app before they appear on printed boarding passes and sometimes before terminal displays are updated.
- Check departure screens immediately after clearing security. Every terminal at ISP has overhead departure boards near the checkpoint exit — confirming your gate here costs 30 seconds and can save a long detour.
- Note which security checkpoint serves your concourse. At multi-concourse airports, entering through the wrong checkpoint can mean exiting security and re-queuing, which adds 20 minutes or more.
- International arrivals follow the customs signs first. If you are connecting from an international arrival, clear U.S. Customs and Border Protection before looking for your domestic connection gate — the process is one-way.
What is the easiest way to navigate Long Island?
Experienced travellers at ISP use a short checklist every time:
- Review the map before leaving home. Open the Long Island official map on your phone while you are still home so the terminal layout is familiar.
- Know your terminal before you arrive. At airports with multiple separate buildings (JFK, LAX, DTW, MSP) confirm your terminal from your boarding pass — rideshare and taxi drivers need the correct terminal to drop you at the right curb.
- Use automated people-movers instead of walking. At large airports with trains (ATL Plane Train, DFW Skylink, DEN AGTS) a single train ride replaces 20–30 minutes of walking. Look for signs to the train immediately after clearing security.
- Follow colour-coded signage. Most airports (TPA Blue/Red, SEA North/South Satellite, PHX T3/T4) use colour or number coding from curbside through gates — picking the right colour zone at check-in means you do not cross the terminal twice.
- Check the live TSA wait before you leave. Knowing the current security wait at ISP lets you time your departure so you arrive at the gate relaxed, not sprinting.
