Location and Accessibility of Terminal 1
Harry Reid International Airport is located at 5757 Wayne Newton Boulevard, Las Vegas, Nevada 89119, only a short distance from the Las Vegas Strip. Allegiant’s official airport information identifies Terminal 1 as its Las Vegas terminal.
Terminal 1 includes ticketing, check-in, baggage claim, security access, restaurants, shops, and access to the A, B, C, and D gate areas. Your specific Allegiant gate can change, so do not rely on a gate number from an earlier trip. Check the Allegiant app, your boarding pass, or the airport’s flight-information displays on the day you travel.
Terminal 1 and Terminal 3 are separate terminal buildings. They are not practical to move between on foot. If you are dropped at Terminal 3 by mistake, use the airport’s free inter-terminal shuttle. The airport states that the shuttle generally operates about every 20 to 30 minutes.
Warning: Confirm “Terminal 1” before leaving your hotel or returning a rental car. Going to Terminal 3 first can add substantial transfer time, particularly during busy travel periods.
Drivers can reach the airport from major Las Vegas roads including I-15, I-215, Paradise Road, and the Airport Connector. Travelers using public transportation can access RTC service from Terminal 1 Level Zero. As of August 2026, RTC’s Maryland Parkway RED LINE has replaced Route 109 and provides an airport connection, while Route 108 also serves the airport area. Because transit routes and timetables can change, check the current RTC schedule before departure.
Amenities and Services Offered at Terminal 1
Terminal 1 provides the core amenities most travelers need before a flight, including seating areas, restrooms, food and beverage outlets, retail stores, information assistance, ATMs, charging opportunities, and airport Wi-Fi. Harry Reid International Airport also lists nursing suites, pet-relief areas, lounges, and other passenger facilities among its airport amenities.
Passengers who need disability-related assistance should arrange airline assistance in advance when possible. Mobility devices such as required wheelchairs and scooters are transported by Allegiant without an additional transportation charge, although passengers should review the airline’s current assistance procedures before travel. The U.S. Department of Transportation also provides guidance for travelers with disabilities.
Families may also find nursing facilities and other family-oriented airport services useful. If you need a specific service, check the airport map before arriving because some amenities are located in particular gate areas rather than directly beside every Allegiant gate.
Note: Harry Reid International Airport has slot machines in the terminals, but gaming is optional and should not distract you from your boarding time or gate changes.
Check-in and Security Procedures at Terminal 1
Allegiant offers online and mobile check-in, which is usually the simplest way to prepare for departure. According to Allegiant’s current passenger guidance, check-in opens 24 hours before scheduled departure and closes 45 minutes before departure.
| Travel step | Current Allegiant guidance |
| Arrive at the airport | At least 2 hours before scheduled departure |
| Online/mobile check-in opens | 24 hours before departure |
| Check-in closes | 45 minutes before departure |
| Checked-bag planning | Allegiant advises passengers dropping checked bags to do so well before departure; its current FAQ instructs passengers to present checked bags at least 1 hour and no more than 2 hours before departure. |
| Recommended gate readiness | Allegiant recommends being through security and in the gate area about 1 hour before departure. |
After check-in and any baggage drop, passengers proceed to TSA screening. Harry Reid International Airport currently lists five TSA checkpoints airport-wide, including three in Terminal 1. Checkpoint operating hours vary, and the best checkpoint may depend on your gate.
Do not plan your airport arrival around a fixed security-wait estimate. LAS displays estimated TSA wait times, but the airport warns that the numbers can fluctuate with passenger volume, staffing, and other conditions.
Adult passengers age 18 and older should also carry an acceptable TSA identification document. Since May 7, 2025, a state-issued driver’s license or identification card generally needs to be REAL ID compliant unless the traveler presents another acceptable form of identification, such as a passport. Review the current TSA acceptable identification list before travel if you are unsure.
Pro Tip: Check in through the Allegiant app before leaving for the airport and save your mobile boarding pass. If you are not checking a bag and no airport document check is required, you can normally proceed toward TSA instead of waiting at a ticket-counter line.

Dining and Shopping Options at Terminal 1
Terminal 1 has a broad mix of quick-service food, coffee, snacks, bars, restaurants, convenience stores, and retail shops. The exact mix differs by concourse, and businesses can change over time, so travelers with a specific restaurant in mind should check the current airport directory before going through security.
Food and shopping are available both before and after security in different parts of Terminal 1. If your flight departs from a more distant gate area, allow enough time to eat or shop without risking a late arrival at the gate.
Travelers can also find Las Vegas-themed gifts and basic travel necessities. Because Terminal 1 covers several concourses, the closest options to your Allegiant gate may be different from the shops you first see near ticketing.
Allegiant Air Flight Schedule and Destinations from Las Vegas
Las Vegas is one of Allegiant’s major leisure markets, and the airline connects LAS with numerous cities around the United States. Allegiant’s current route map includes a large number of nonstop markets, while some routes operate only seasonally or on selected days of the week.
For that reason, a fixed list of destinations in an airport guide can quickly become outdated. Before planning a trip, check Allegiant’s live route map and booking calendar for your intended dates. A route that operates during one season may not operate on the same days or at the same frequency later in the year.
Passengers should also recheck flight status on the day of travel. Gate assignments, departure times, and operational details can change even when the scheduled route remains the same.
Ground Transportation Options from Terminal 1
Terminal 1 has several transportation choices for reaching the Strip, downtown Las Vegas, residential areas, hotels, and destinations beyond the airport. Pickup areas differ by transportation type, so following the airport’s signs is important.
| Transportation | Terminal 1 location / guidance |
| Uber / Lyft | Level 2 of the Terminal 1 parking garage. Follow the pedestrian bridge from the terminal toward the garage. |
| Taxi | East side of baggage claim, outside exit doors 1–4. |
| RTC public bus | Level Zero at the covered RTC stop. As of August 2026, airport-area service includes Route 108 and the new RED LINE that replaced Route 109. Verify the latest schedule before travel. |
| Rental-car shuttle | From baggage claim, follow signs to Ground Transportation on Level 1. The Rent-A-Car Center shuttle stop is outside doors 10 and 11. |
| Group / hotel shuttles | Services use designated ground-transport areas; Terminal 1 group-shuttle service is available on the west side of baggage claim near doors 7–13. |
| Inter-terminal shuttle | Level Zero. Free service connects Terminal 1 and Terminal 3 and generally runs about every 20–30 minutes. |
The airport’s consolidated Rent-A-Car Center is not inside Terminal 1. Free airport shuttles transport rental-car customers between the terminals and the facility on Gilespie Street.
The Las Vegas Monorail does not directly serve Harry Reid International Airport. Travelers who want to use the Monorail for Strip transportation must first reach a Monorail station using another mode of transportation.
Tips for Navigating Terminal 1 and Making the Most of Your Time
Start by confirming Terminal 1 before leaving for the airport. Then check in through Allegiant’s website or app when the 24-hour check-in window opens. Save your boarding pass and verify whether you need to stop at the ticket counter for checked baggage or another document requirement.
Arrive at least two hours before scheduled departure, and add more buffer time during holidays, large Las Vegas events, severe weather, or periods of heavy airport traffic. LAS publishes estimated TSA wait information, but those estimates can change quickly and should not be used as a reason to arrive late.
Once through security, verify your gate again. Terminal 1 serves several gate areas, and walking or tram time can be longer than expected depending on your departure gate.
The safest airport plan is simple: confirm Terminal 1, arrive at least two hours early, finish security with time to spare, and recheck your Allegiant gate before boarding.
Current travel note: As of August 2026, LAS is repaving the Airport Connector Tunnel. Lane reductions are expected through the end of December 2026, so drivers should allow extra road time while the project is active.
Allegiant Air Customer Service and Support at Terminal 1
For reservation changes, baggage questions, check-in problems, flight disruptions, or Allegiant policies, contact Allegiant rather than the airport. Allegiant lists its Customer Care number as 702-505-8888.
For questions about airport facilities, parking, transportation, or general Harry Reid International Airport services, the airport’s main information number is 702-261-5211.
If an item is lost inside an aircraft or involves checked baggage, start with Allegiant. If an item is lost in a public airport area, use Harry Reid International Airport’s Lost & Found service. Separating airline issues from airport-facility issues can help you reach the correct team faster.
Future Developments and Expansion Plans for Terminal 1
Harry Reid International Airport has published a larger modernization and capacity plan rather than simply discussing unspecified future improvements. The airport has announced plans that include expanding Terminal 1 with 26 additional gates, replacing portions of the existing A and B gate configuration with a new pier-style design, improving airport road circulation, and creating new multimodal transportation centers.
The airport has also discussed eventually redesignating Terminal 3 as Terminal 2 and rebalancing airline operations to reduce pressure on Terminal 1. These are long-term airport plans, so passengers should not assume that every proposed element has already been built or opened.
For Allegiant travelers, the practical takeaway is that Terminal 1 will continue to evolve as LAS works to accommodate future passenger demand. Construction zones, roadway patterns, gate facilities, transportation pickup areas, and airline assignments may change as projects move forward.
