United Terminal and Gate Location at LAS
Harry Reid International Airport lists United Airlines at Terminal 3 for ticketing, check-in, and baggage claim. United aircraft use the D Gates satellite concourse, so your terminal and gate area are not the same physical space.
| Travel Step | Where to Go |
|---|---|
| Ticketing, check-in, and bag drop | Terminal 3 |
| Security screening | Terminal 3 checkpoint for D and E Gates |
| United departure gates | D Gates via the Red Line automated tram |
| United baggage claim | Terminal 3 |
| United Club | D Gates, after security |
Warning: Do not assume that checking in at Terminal 3 means your gate is inside the main Terminal 3 building. Allow time after security for the tram ride and the walk to your assigned D Gate.
United Airlines Check-In and Baggage Drop
United provides staffed counters and self-service kiosks in Terminal 3. A staffed counter is useful when you have an international itinerary, need document checks, are traveling with special items, or require mobility or other assistance. At a kiosk, you may be able to print a boarding pass and bag tags before taking checked luggage to the designated bag-drop counter.
You can also check in with United beginning 24 hours before departure. The United app can store your mobile boarding pass and show flight, gate, and boarding updates. If you are not checking a bag and do not need an agent, you can usually go directly to security after completing check-in.
Checked-bag allowances, fees, and cutoff times vary by route, fare, status, and destination. Review the details attached to your reservation and use United’s checked-bag fee calculator before travel. Arriving early does not override a missed airline bag-drop deadline.
Note: If you need wheelchair service or another accommodation, request it through United before your trip when possible, then identify yourself at the Terminal 3 counter when you arrive.
Security and the Tram to the D Gates
Terminal 3 has security screening for the D and E Gates. Check current checkpoint information on the airport’s official security page, because operating hours and wait times can change.
- Complete United check-in and baggage drop in Terminal 3.
- Follow signs to the Terminal 3 security checkpoint.
- After screening, follow signs down to the Red Line tram station.
- Ride the automated tram to the D Gates.
- Check the United app or airport display again, then walk to your assigned gate.
The D Gates are a satellite concourse connected to both passenger terminals by automated trams. You cannot walk between Terminal 1 and Terminal 3 outside the secure area. A free inter-terminal shuttle is available landside when you need to move between terminal buildings.
Pro Tip: Take a screenshot of your boarding pass before entering the airport. It remains easy to open if cellular service slows, although you should still watch the United app and airport screens for gate changes.
Terminal Facilities and Family Amenities
Wi-Fi, Charging, and Water
LAS offers free airport Wi-Fi. The D Concourse also has seating areas with power outlets, although an outlet may not be available beside every seat. Post-security water refill stations let you refill an empty reusable bottle after screening.
Facilities for Families
Private nursing suites and family-care restrooms are available at the airport. A children’s play area is located on the tram level between Terminal 3 and the D Gates, making it convenient for many United passengers. Check the airport’s amenities directory or map for the nearest facility.
Accessibility and Other Services
Elevators, accessible restrooms, visual paging, pet-relief areas, information services, and mobility-assistance resources are available across LAS. Airline staff handle wheelchair service connected with a flight, so arrange that assistance with United rather than relying only on airport information desks.
Dining and Shopping Options
Note: Restaurant, shop, and concession hours change with vendor schedules and flight activity. Use the airport’s live directory before relying on a specific outlet, especially for an early-morning or late-night departure.
| Area | What You Can Expect |
|---|---|
| Terminal 3 public areas | Travel essentials, grab-and-go items, and selected retail near ticketing or baggage claim |
| D Gates | Coffee, quick-service food, sit-down dining, bars, candy, newsstands, souvenirs, and specialty retail |
| Terminal 3 and E Gates | Additional dining, shopping, and duty-free choices, but access depends on your location and secure-area routing |
Because United passengers normally board in the D Gates, focus on D Concourse options after taking the tram. Browse the official LAS dining and shopping directory for current locations and hours.
United Club Lounge
The United Club at LAS is located in the D Gates after security. The airport lists complimentary bar service, light snacks, and free Wi-Fi among its amenities. It is a practical place to work, charge a device, or wait away from the main gate seating area.
Access is not included with every United ticket or every premium seat. Eligibility can depend on a United Club membership, a qualifying same-day itinerary, an eligible card benefit, Star Alliance lounge rules, or a valid one-time pass. Capacity restrictions can also apply. Review United’s current United Club and lounge information before your trip.
The official airport description does not list showers at this lounge. Do not plan around shower access unless United confirms that amenity for your travel date.
Transportation from Terminal 3
Uber and Lyft
Terminal 3 rideshare pickup is on the Valet Level of the parking garage, not directly at the arrivals curb. From baggage claim, follow airport signs to the pedestrian bridge, cross to the garage, and take the elevator or stairs to the Valet Level. Verify the driver’s name, vehicle, and license plate in the app before entering.
Taxis
Taxis wait outside Terminal 3 on Level Zero near Door 52. This is separate from the rideshare pickup area. Follow the signs from baggage claim rather than going to the parking-garage rideshare zone.
RTC Public Bus
The Terminal 3 public-bus stop is on Level 2 across from Door 44. The Centennial Express (CX) serves Terminal 3. Routes 108 and 109 use Terminal 1, so passengers who need those routes can take the airport’s free inter-terminal shuttle to Terminal 1. Use the RTC airport route planner because routes, transfers, and schedules can change.
Rental Cars and Private Transportation
The airport’s Rent-A-Car Center is off-site. Courtesy rental-car shuttles pick up Terminal 3 passengers on Level Zero at both ends of the terminal. Private shuttles, limousines, and prearranged car services also use designated Terminal 3 pickup areas, so follow the instructions from your provider.
Note: The Las Vegas Monorail does not serve the airport. A taxi, rideshare, bus, rental car, or other ground-transport service is required to leave LAS.
Parking, Drop-Off, and Passenger Pickup
Drivers dropping off a United passenger should follow signs for Terminal 3 Departures. Passenger pickup is across from Terminal 3 on Level 1 of the parking garage and is intended for immediate loading. If the traveler is not ready, the driver should use the airport’s cell-phone lot or short-term parking instead of waiting at the curb.
Terminal 3 has short-term, long-term, economy, valet, and reservation parking options. Rates and availability can change, so check the airport’s Terminal 3 parking page before driving to LAS.
Tips for Navigating the United Airlines Terminal
- Arrive early. LAS recommends arriving at least two hours before a domestic flight and three hours before an international flight.
- Confirm both terminal and gate. Terminal 3 is the United check-in location, while the D Gates are the usual boarding area.
- Allow time for the tram. Security, the walk to the tram, the ride, and the walk to your gate all add time.
- Use mobile check-in. A mobile boarding pass can reduce time at the ticketing area when you have no checked luggage or document issue.
- Check security information. Airport checkpoint hours and wait estimates can change during busy periods.
- Pack for screening. Review current TSA rules, keep travel documents easy to reach, and bring an empty refillable water bottle.
- Watch for changes. Recheck the United app and airport displays after security and again when you reach the D Gates.
