These kiosks are located throughout the airport and allow travelers to print boarding passes, check bags, and generate bag tags in just a few minutes. They are handy for passengers who want to avoid waiting in long lines at staffed counters.

What Should You Know Before Visiting the LAS Airport?
Before arriving at LAS, review the Transportation Security Administration’s (TSA) 3-1-1 rule for liquids. Each liquid container must be 3.4 ounces (100 milliliters) or less, and all containers should be accommodated inside a single quart-sized, transparent, plastic bag. This rule applies to every traveler’s carry-on, so organizing your items in advance helps you avoid delays at security checkpoints.
To know more about restricted and permitted items, the TSA website provides official guidance. Checking these rules before you pack ensures that your luggage complies with federal regulations and keeps your check-in experience stress-free.
How Early to Reach for a Hassle-free LAS Check-in Experience?
For a smooth and stress-free check-in at the Harry Reid International Airport, plan your arrival carefully:
- Domestic Flights: Arrive at least 2 hours before your scheduled departure.
- International Flights: Arrive at least 3 hours before departure.
Las Vegas is a 24/7 destination, and the airport is always active. During peak periods such as weekends, holidays, or major conventions, allow extra time to account for heavier crowds. Always confirm check-in times with your airline, as individual carriers may have different recommendations.
What Travel Documents Do You Need at LAS?
Travelers must carry all necessary documents, including a boarding pass and valid photo identification. Acceptable IDs include REAL ID-compliant driver’s licenses or passports. If you’re unsure whether your license meets REAL ID standards, consult official government resources before your trip.
Children under 18 are not required to present identification when traveling within the United States. However, airlines may have specific requirements for minors, so it’s best to confirm with your carrier in advance. Preparing these documents early ensures you can complete check-in quickly and move on to security without complications.
How Does TSA Security Screening Work At the LAS Airport After Check-In?
Once you’ve checked in, the next step is TSA security screening. Harry Reid International Airport operates several checkpoints across its terminals, each with specific hours of operation:
- A/B Checkpoint: 3:30 a.m.–1 a.m.
- C Annex Checkpoint: 3:05 a.m.–9:30 p.m.
- C/D Checkpoint: Open 24 hours
- Terminal 3 Checkpoint: 3:30 a.m.–1:30 a.m.
- Innovation Checkpoint (Terminal 3): 6 a.m.–2 p.m.
Knowing which checkpoint serves your terminal and when it operates is essential for planning your arrival. For example, the C/D checkpoint remains open 24 hours a day, making it a reliable option for late-night or early-morning flights. By checking these hours in advance, you can avoid unnecessary waiting and ensure you reach your gate on time.
