What If You Arrive at the Wrong Terminal?

The airport provides a complimentary inter-terminal shuttle.
- Terminal 1 pickup: Level 0 of the parking garage.
- Terminal 3 pickup: Level 0 outside the terminal.
- Shuttle frequency: Approximately every 20–30 minutes.
- Travel time: Approximately 10 minutes.
Allow additional time for waiting, walking, and baggage check-in.
How Early Should You Arrive at Las Vegas Airport?
The airport recommends arriving at least two hours before domestic departures and three hours before international flights.
Domestic Flights
For a domestic flight departing at 2:00 PM, plan to reach your airline’s terminal by approximately noon.
This allows time for checking bags, security screening, and reaching your gate.
International Flights
For an international flight departing at 6:00 PM, plan to arrive around 3:00 PM.
Some airlines require additional document checks, so review your carrier’s check-in instructions.
Busy Travel Days
Allow extra time after major Las Vegas events, including CES, Formula 1, large conventions, and holiday weekends.
Sunday and Monday departures can also be busy, depending on hotel occupancy and flight schedules.
Adding 30–45 minutes during expected peak periods is a reasonable precaution, but not an official airport requirement.
Las Vegas Airport Checked Baggage Cutoffs
Airlines enforce separate deadlines for checking luggage.
For example, Southwest generally requires domestic checked bags at least 45 minutes before departure, while international baggage deadlines are typically earlier.
Other airlines may use different rules.
| Baggage Rule | What to Know |
|---|---|
| Domestic Bag Drop | Verify your airline’s deadline |
| International Bag Drop | Often earlier than domestic flights |
| Southwest Domestic Bags | At least 45 minutes before departure |
| Southwest Early Bag Drop | No earlier than 4 hours before departure |
| Oversized Luggage | May require additional processing |
| Late Check-In | Bags or passengers may be refused |
Important: Completing online check-in does not extend the deadline for handing over checked luggage.
Can You Check Bags Six Hours Early?
Not always.
Southwest generally accepts checked baggage no earlier than four hours before departure.
Other airlines may have different acceptance windows.
If your hotel checkout is at 11:00 AM but your flight leaves late in the evening, ask your hotel about luggage storage rather than assuming the airport will accept your bags immediately.
TSA Security Checkpoint Hours at LAS
Harry Reid International Airport currently has five security checkpoints.
| TSA Checkpoint | Operating Hours |
|---|---|
| Terminal 1 A/B Gates | 3:15 AM–1:00 AM |

Published operating hours may change before.
Full Info: Las Vegas Airport TSA Wait Times: Security & Tips
TSA PreCheck and CLEAR
TSA PreCheck and CLEAR can reduce some screening steps for eligible passengers.
However, expedited screening lanes do not necessarily operate throughout the entire airport security checkpoint schedule.
Check current hours before relying on either program for a late-night or early-morning departure.
REAL ID Requirements
The federal REAL ID enforcement date was May 7, 2025.
Domestic passengers age 18 and older must present a REAL ID-compliant license or another TSA-accepted identification document, such as a valid passport.
Passengers without acceptable identification may face additional identity verification and delays.
Getting to the D Gates at Las Vegas Airport
D Gates are accessible through the airport’s automated tram system.
Passengers checking in at Terminal 1 can use the Blue Line Tram to reach D Gates after security.
Passengers using Terminal 3 can take the Red Line Tram.
Because the D Gates are connected to both terminal systems, the gate letter alone does not identify your airline’s correct check-in terminal.
Best tip: Confirm your airline’s ticket counter location first, then follow signs to security and your assigned gates.
Travelers with carry-on baggage only may have additional airside transfer options after clearing security, but should follow airport signage and airline instructions.
Curbside Check-In & Express Bag Drop
Selected airlines offer curbside check-in or expedited baggage services at LAS.
Availability depends on the airline, terminal, operating hours, and staffing.
Curbside Check-In
Curbside baggage services may allow eligible travelers to check bags without entering the main ticketing hall.
Airline baggage charges and service fees may apply.
Airport Curbside Concierge
Harry Reid International Airport has also offered curbside baggage services at Terminal 3 and the Rent-A-Car Center.
Check current operating hours and participating airlines before using these services.
Online check-in and prepaid baggage can also simplify airport processing, but they do not eliminate baggage deadlines or security screening.
Returning a Rental Car Before Your Flight
The Harry Reid Rent-A-Car Center is separate from both passenger terminals.
Address: 7135 Gilespie Street, Las Vegas, NV 89119.
After returning your rental car, follow signs to the complimentary airport shuttle.
The shuttle serves both terminals.
Allow at least 30–45 additional minutes for returning your vehicle, waiting for transportation, and reaching the check-in counter.
During busy periods, extra time may be helpful.
Tips for Faster Las Vegas Airport Check-In
- Confirm your terminal: Check the airport’s airline directory before arranging transportation.
- Check in online: Use your airline’s app whenever available.
- Review baggage deadlines: Do not assume every airline has the same cutoff.
- Monitor TSA wait times: Check the airport website before leaving your hotel.
- Prepare identification: Keep your passport or acceptable ID accessible.
- Allow tram time: D Gate departures require additional movement through the terminal.
- Return rental cars early: The rental center is not inside the passenger terminal.
Conclusion
Las Vegas airport check-in is easier when you know your airline’s terminal, baggage deadlines, and TSA checkpoint hours. Aim to arrive two hours before domestic flights and three hours before international departures. Check your terminal assignment before leaving the Strip, especially if checking luggage. Use online check-in when available, monitor security wait times, and allow extra time for rental car returns or D Gate transfers.
