How To Get Between Terminals at Harry Reid International Airport [LAS]

Harry Reid International Airport (LAS) is the busiest airport in Nevada. It is in Las Vegas, a stone’s throw from the Las Vegas Strip, and is the closest airport to Grand Canyon National Park, Death Valley National Park, and various other national parks.

The airport has 2 terminals: Terminal 1 and Terminal 3. As they are not connected, shuttle buses and trams make getting between them easy.

Terminal 1 handles most domestic flights departing from the A, B, C, and D gates. Terminal 3 serves domestic and international flights, operating from the D and E gates.

Since terminals 1 and 3 are not connected, passengers should confirm their correct terminal in advance to avoid arriving at the wrong terminal. If a terminal transfer is needed, a shuttle bus runs every 20 to 30 minutes, with pickup locations on level 0 of both terminals.

Once passengers pass through security, they can travel between all gates by riding the airside trams.

Pre-Security (Landside) Ground Transportation at LAS

Airport Shuttle Bus

Passengers who need to transfer between terminals must use the airport shuttle bus.

The airport shuttle bus runs every 20 to 30 minutes and takes 5 to 10 minutes, depending on traffic. Since the bus operates outside the secure area, passengers must go through security upon arrival at the onward terminal.

Shuttle pickups are at Terminal 1 on level 0 near the parking garage and at Terminal 3 on level 0 outside door 55.

Terminal 1

Level 1 Check-in and Arrivals

Check-in and baggage claim are on level 1. The terminal road provides curbside access to both areas, running under a pedestrian bridge that houses the upper-level departures. Beyond baggage claim, there’s another pedestrian bridge leading to the parking garage for passenger pickup. Some ground transportation, including rental car shuttles, is on this level.

Level 2 Departures

Once checked in, passengers can take the escalator to level 2, where there are 3 security checkpoints. The security checkpoint immediately above the central check-in area is best for the A and B gates, the checkpoint south of check-in is best for the C gates, and the checkpoint above baggage claim is for the C or D gates.

A Gates

The A gates are on the northwest side of Terminal 1 and are to the right as you come out of the A/B security checkpoint. Gates A3 and A5 are at the concourse entrance, gates A7 to A15 are at the end to the left, and gates A17 to A23 are at the end to the right.

B Gates

The B gates have 17 gates and are positioned southwest of Terminal 1. After clearing the A/B checkpoint, passengers should take the left walkway where gates B1, B2, and B6 are located. Further along the concourse, gates B9 to B15 are to the left, and gates B17 to B25 are to the right.

There’s an additional pedestrian bridge off this central area that leads to the C gates.

C Gates

The C gates are southeast of Terminal 1 and have 2 security checkpoints that provide the best access. Passengers can choose to come through the C annex checkpoint to walk to the closest departure gates or the C/D checkpoint for immediate access to the green line tram to reach the farthest gates.

The C gates have 17 gates numbered C1 to C5, C7 to C9, C11, C12, C14, C16, C19, and C21 to C25. Once inside the secure area, passengers can walk between gates A and B or take the blue line tram to the D gates.

D Gates

The D gates are a remote concourse, south of Terminal 3, connected only by an underground tram. This X-shaped concourse has 4 gate areas: gates D1 to D14, gates D16 to D25, gates D32 to D42, and gates D50 to D59.

Passengers can access the D gates by clearing the Terminal 1 or Terminal 3 security checkpoints. The blue line tram runs between Terminal 1 and the D gates, and the red line tram runs to and from Terminal 3. The tram platform is on the lower level of the concourse, with escalators and elevators transporting passengers up to the departure level.

There’s a good selection of shops and restaurants, a Centurion Lounge near gate D16, and a Capital One Lounge off the central area.

Terminal 3

Level 0 Arrivals

Arrivals and baggage claim are on level 0 of Terminal 3. This is the same level as the tram to the D gates and the lower-level security checkpoint. International arrivals are processed through immigration and customs on this level.

Level 1 Mezzanine

Passengers can walk across the pedestrian bridges from the terminal to the parking garage.

Level 2 Departures and E Gates

Check-in is on level 2, with curbside drop-off outside the terminal building. The security checkpoint is in the middle of the check-in area.

After security, passengers will arrive at the E gates departure area, which has 14 gates numbered E1 to E15. The concourse is 2,231 feet long and takes around 10 minutes to walk from end to end. Several moving walkways assist passengers along the route.

Flight Connections at LAS

Connecting between the A, B, and C gates at LAS is generally straightforward, as airside walkways link all 3. If you don’t need to collect checked luggage, you can remain inside the secure area and walk directly to your next gate. However, if you’ve booked separate tickets and need to retrieve your bags, you’ll have to exit security, recheck your luggage, and go through security again.

International arrivals into Terminal 3 must collect luggage, clear customs, and recheck bags for onward flights. If your next flight departs from the A, B, or C gates, you must take the shuttle bus between terminals.

For those who can stay within the secure area, connections from A, B, or C gates to the D or E gates are possible via the underground tram.

Final Thoughts

Harry Reid International Airport is just minutes from the iconic Las Vegas Strip, so it’s a convenient entry point to explore the city and beyond. If you’re feeling lucky, slot machines are located throughout the terminals, offering a taste of Vegas the moment you arrive.

Whether LAS is your final stop or a connection point, the airport is relatively easy to navigate. However, if you need to transfer between Terminal 1 and Terminal 3 outside the secure area, shuttle buses run only 2 to 3 times per hour, so allow extra time to make your connection without stress.
