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 JNU handles — which airlines fly from it, the gate range, and key amenities to know before you go.
JNU has a single, compact two-story terminal building with no separate concourses. The first floor holds airline ticketing/check-in counters (Alaska Airlines, seasonal Delta, and regional/bush carriers such as Alaska Seaplanes, Air Excursions, and Ward Air), baggage claim, rental car counters (Alamo, Avis, Budget, Hertz), the Hummingbird Hollow Gift Shop, and a visitor information desk. The second floor holds the airport's single TSA security checkpoint, six boarding gates, waiting-lounge seating, and the Tailwind Concessions food and beverage counters. Everything is centrally located, so there is little walking distance between any two points in the building.
Not applicable — JNU has only one terminal building and one concourse, so there is no inter-terminal transport (train, shuttle, or long walkway) to worry about. Passengers move on foot between the first-floor ticketing/baggage area and the second-floor security/gates area via stairs or an elevator.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at JNU — 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 JNU is a single small terminal with one checkpoint and six gates, there's no risk of going to the wrong concourse — the only real navigation decision is arriving early enough during summer cruise season (May–September) or the morning departure bank, when the one checkpoint is the only bottleneck for every flight in the building.
A few habits that prevent last-minute sprints:

Your boarding pass shows the exact gate. 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.
