Leaving Las Vegas might not be as thrilling as arriving, but with a little planning, your departure through Harry Reid International Airport (LAS) can be just as smooth. One of the most important things to check before heading to the airport? The Las Vegas airport security wait times.

What Causes Delays at LAS?

Las Vegas attracts millions of visitors each year. Big events, conventions, and weekend getaways lead to a surge in passengers, especially at peak hours. Security lines tend to back up at:

• Early mornings (5–8 AM)

• Fridays and Sundays

• After major Vegas events

Add in weather or staffing issues, and even seasoned travelers can be caught off guard.

Your Pre-Flight Checklist

To save time and avoid stress, here’s what you should do:

• Check live TSA wait times at LAS Wait Times

• Arrive early—2 hours for domestic, 3 for international

• Enroll in TSA PreCheck or CLEAR if you’re a frequent flyer

• Pack smart to avoid having your bag manually inspected

• Know your terminal—T1 and T3 serve different airlines and may have very different wait times

Stay One Step Ahead

Even if you're running late, knowing real-time Las Vegas airport security wait times can help you make decisions quickly. If security at your terminal is backed up, airport staff might redirect you to another checkpoint nearby.

Conclusion

Travelers flying out of Las Vegas should take security wait times seriously. A bit of preparation ensures you leave the city on time—and without the chaos. Whether you're heading home or on to another destination, make security lines the easiest part of your trip.
