Official map
Harlingen official terminal map — airport authority website
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 HRL handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Valley International Airport has a single small terminal building with 7 gates total, no jet-bridge concourse complex, and no inter-terminal transit needed. Gate assignments: Gate 1 — Sun Country Airlines (seasonal); Gate 2 — Delta Air Lines (seasonal); Gate 4 — American Airlines/American Eagle; Gates 5–6 — Southwest Airlines (HRL's dominant carrier and only Southwest hub in the Rio Grande Valley region); Gate 7 — United Express. Ticketing, security, baggage claim, and all gates sit within the same compact building, and the walk from curb to any gate takes only a few minutes.
Single terminal, single concourse — there are no trains, trams, or shuttle buses between gates. Every gate is reachable on foot in a few minutes from the single security checkpoint.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at HRL — 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.
HRL is one of the smallest terminals you'll fly through — there is one check-in hall, one security checkpoint, and all 7 gates open onto the same short concourse, so you cannot get lost. The official airport website does not currently publish a dedicated interactive terminal map (its old 'Terminal Information & Amenities' page is offline), so there's no need to hunt for one — the terminal is simple enough to navigate on sight.

Look for departure boards throughout the terminal for real-time gate information.
