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 LAS handles — which airlines fly from it, the gate range, and key amenities to know before you go.
Main domestic terminal with three concourses. Concourse A (16 gates: A3–A23): Allegiant Air and small regional/charter carriers (Advanced Air, Contour Aviation). Concourse B: Frontier Airlines and Sun Country Airlines. Concourse C (17 gates: C1–C25): exclusively Southwest Airlines. Terminal 1 connects airside to the standalone Concourse D satellite via the Blue Line automated tram.
International and major-carrier terminal. Concourse E (14 gates: E1–E12, E14–E15): Delta Air Lines, United Airlines, American Airlines, Alaska Airlines, JetBlue, Hawaiian Airlines, plus all international carriers (British Airways, Air Canada, WestJet, Aeromexico, Volaris, and others). Has dedicated international arrivals hall with US Customs and Border Protection. Connects airside to Concourse D via the Red Line automated tram.
Three separate automated people-mover (tram) lines run airside: Green Line (Terminal 1 main hall to Concourse C), Blue Line (Terminal 1 to standalone Concourse D), and Red Line (Terminal 3 to Concourse D). Airside passengers can transfer between T1 and T3 by chaining the Blue and Red Lines through Concourse D, but Terminals 1 and 3 have no direct airside walkway. Passengers who have not yet cleared security travel via a free shuttle bus running every 20–30 minutes from Level 0 of each terminal building, but must re-clear security upon arrival at the other terminal.
Timing tip
Always allow 15–30 minutes for any inter-terminal transfer at LAS — 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.
Terminal 1 and Terminal 3 are entirely separate buildings serving different carrier groups — budget and domestic carriers (Southwest, Allegiant, Frontier, Sun Country) use Terminal 1, while major network carriers and all international flights (Delta, United, American, Alaska, JetBlue, international airlines) use Terminal 3. Confirm your terminal before you leave for the airport; a last-minute terminal switch means a 20–30 minute shuttle bus ride plus re-clearing TSA security.
A few habits that prevent last-minute sprints:

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.
