You’re landing at Harry Reid International Airport—most of us still call it McCarran, honestly—and you’re praying you don't have to hike three miles just to find a taxi. If you are flying international or on a big carrier like United or JetBlue, you’re headed to Terminal 3. It’s the "new" side of the airport, though "new" is relative since it opened back in 2012.
Most people get confused because Vegas isn't laid out like a normal airport. There is no Terminal 2. It's gone. Demolished. So now we just have 1 and 3, and they aren't even connected by a sidewalk. If you go to the wrong one, you’re looking at a 15-minute shuttle ride that feels like an hour when your flight departs in 40 minutes.
Terminal 3 is basically a massive, 1.9-million-square-foot glass box. It cost about $2.4 billion to build. It’s sleek. It’s shiny. It also has some of the shortest TSA lines in the country if you catch it at the right hour, mostly because it handles a lot of the international wide-body jets that only take off once or twice a day.
The Airlines That Actually Live Here
Don't show up at Terminal 1 for a flight to London. You'll miss it. Terminal 3 is the exclusive home for all international arrivals and departures. If you are on British Airways, Virgin Atlantic, AeroMexico, or WestJet, this is your house.
Domestic travelers use it too. United Airlines, Alaska, JetBlue, Hawaiian, and Sun Country all operate out of the E Gates here. It’s a bit of a trek. If you’re flying United, you’re likely at the far end of the terminal. The walk from security to the furthest E gate is long enough that you might actually hit your daily step goal before you even board the plane.
Contrast that with Terminal 1, which houses Southwest, Spirit, and Delta. T1 is crowded. It’s loud. It smells a bit more like stale cigarettes and desperation near the slot machines. Terminal 3 feels like a library by comparison. It’s airy. The ceilings are high. There’s a lot of natural light coming through those floor-to-ceiling windows, which is great until the 110-degree Vegas sun starts beating down on the tarmac.
Navigating the Baggage Claim Trap
Here is a pro-tip that saves lives: Terminal 3 has its own parking garage and its own baggage claim. This sounds obvious, but the airport layout is deceptive.
If you are picking someone up, you have to know their airline. There is no "main" arrivals area. If your friend is on United, you go to the T3 arrivals curb. If they are on Southwest, and you go to T3, you are going to be waiting a long time while they stand at T1.
The Terminal 3 baggage claim is located on Level 0. It’s usually pretty fast. Since fewer airlines share the carousels here compared to the madness of Terminal 1, your bags often beat you to the curb. Plus, the ride-share pickup for Uber and Lyft is located on Level V of the T3 parking garage. It’s a bit of a walk—up the elevator, across the bridge—but the wait times for a car are usually shorter than the legendary lines at Terminal 1.
Where to Eat Without Breaking the Bank
Look, airport food is a ripoff everywhere. We know this. But Terminal 3 has some decent spots if you aren't in the mood for a soggy sandwich.
The Village Pub is a local favorite. They have a location in the terminal that serves actual food—fish and chips, burgers, and decent beer. It doesn't feel like an "airport" bar as much as a "Vegas" bar. There’s also a Pei Wei and the standard Starbucks, but the lines at Starbucks in T3 can get weirdly long because there are fewer coffee options spread out across the gates.
If you have a lounge membership, the Club at LAS in Terminal 3 is located near Gate E2. It’s accessible via Priority Pass. It’s not the Centurion Lounge—that’s over in Terminal 1’s D Gates—but it has clean bathrooms, free snacks, and a quiet place to charge your phone. If you are flying business class on an international carrier, you might get access to the more premium lounges, but for the average traveler, the Club at LAS is the go-to sanctuary.
The Secret Connection: The Blue Line Tram
People get panicked when they see "D Gates" on their boarding pass but their airline is listed at Terminal 3. Don't freak out.
Terminal 3 is connected to the D Gates via an automated people mover called the Blue Line. It takes about three minutes. The D Gates are technically a satellite terminal shared by both Terminal 1 (via the Blue Line) and Terminal 3 (via the Red Line).
Wait, I got that backwards—let’s be precise. The Blue Line connects T1 to the D Gates. The Red Line connects T3 to the D Gates. It’s a "hub and spoke" system. This means if you are flying United, you check in at T3, go through security at T3, and then hop on the Red Line tram to get to your gate in the D concourse.
It’s actually a very smooth system unless the tram breaks down, which happens once in a blue moon. Just watch the signs. They are color-coded for a reason. Blue for T1, Red for T3. If you see blue signs and you parked at Terminal 3, you are going to have a very bad walk back to your car.
TSA and the Security Shuffle
Terminal 3 has two main security checkpoints. There is one on the East side and one on the West side.
Generally, the West checkpoint is for the domestic flights (United, etc.) and the East is for international. However, if one line looks like a nightmare, you can usually use either one and just walk across the bridge.
The TSA PreCheck lanes here are usually efficient. Clear is also available. Because the terminal is so spread out, the "crowd" feeling is minimized. You don't feel like cattle being herded as much as you do in the older parts of the airport. It's civilized. Mostly.
Why Does This Terminal Even Exist?
Back in the mid-2000s, Vegas was exploding. The old Terminal 2 was a tiny, cramped building that handled international flights like a Greyhound station. It couldn't handle the massive Boeing 747s and Airbus A380s coming in from London and Seoul.
The county decided to go big. They built Terminal 3 to be the "Front Door" of Las Vegas for the world. They added 14 gates directly in the terminal and connected it to the existing 44 gates in the D concourse.
It changed the game for international tourism. Now, when a flight lands from Zurich, passengers go through a massive, modern Customs and Border Protection (CBP) facility that can process hundreds of people an hour. It’s still a government process, so "fast" is a relative term, but it beats the old days by a mile.
Practical Steps for Your Next Trip
If you want to survive Terminal 3 without a headache, follow these rules. No exceptions.

- Check your terminal before you leave the hotel. Look at your digital boarding pass. If it says Alaska, United, JetBlue, or any international carrier, tell your driver "Terminal 3." If they argue, they're wrong.
- Park in the T3 garage. It is almost always less crowded than the T1 garage. Even if you are flying an airline in Terminal 1, some savvy locals park at T3 and take the tram just to avoid the T1 parking nightmare.
- Give yourself 20 minutes for the tram. If your flight is at a D gate but you're checking in at T3, you have to clear security, walk to the tram station, wait for the train, and then ride it. Do not cut it close.
- Download the FlyLAS app. It actually has real-time wait times for the security checkpoints at T3. Sometimes the difference between the East and West checkpoints is 15 minutes.
- Use the Level V Ride-Share. Don't go to Level 0 for an Uber. You will be standing there forever wondering where the cars are. Follow the signs for "Ride Share" up to the parking garage.
Terminal 3 isn't just a building; it’s a logistics hub designed to keep the chaos of 50 million annual visitors from imploding. It has its quirks—the long walks, the confusing tram colors—but once you figure out the flow, it is objectively the superior way to enter or exit the Mojave Desert. Use the space to your advantage, grab a drink at the Village Pub, and keep your eyes on the red signs.
