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 ITO handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Hilo International Airport has a single passenger terminal complex made up of three interconnected buildings totaling roughly 220,000 square feet, positioned at the southern edge of the airfield off Kekuanaoa Street. Ticket lobbies, airline check-in counters, concessions, the single security checkpoint, and the passenger holding area are all on the ground level; escalators and an elevator carry passengers up to the second-level boarding gates, which use level-entry loading bridges. The terminal has 7 passenger loading bridges serving an apron with 10 aircraft parking positions (8 usable, sized up to Boeing 747). The Hawaiian Airlines Premier Club lounge is in the northwest corner of the first-floor departure lounge. Only two airlines currently operate scheduled service: Hawaiian Airlines (to Honolulu and Kahului) and Southwest Airlines (to Honolulu, with Las Vegas service starting August 2026) — ITO has no scheduled nonstop flights to the US mainland or internationally, unusual among Hawaii's larger airports.
A separate, smaller commuter terminal building (about 4,040 sq ft) sits roughly a quarter mile west of the main terminal and handles general aviation and small commuter operations; the airport's free cell phone waiting lot is located on the east side of this building.
Single-terminal airport with no airside or landside shuttle required — all check-in, security, and gates are within one connected building, reached via a short walk plus one flight of escalators/elevator between the ground-level ticketing/security level and the second-level gates.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at ITO — 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 ITO has only one terminal and one security checkpoint, navigation is simple, but the Commuter Air Terminal (used by some general aviation and small operators, and home to the cell phone waiting lot) is a separate building about a quarter mile west of the main terminal — confirm which building your flight or pickup uses before you head out.

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.
