How early should I arrive at Harry Reid International Airport?
Posted on Feb 06, 2026 / Travel
Most travelers are told to arrive about two hours before a domestic flight and a bit earlier for international flights. Security wait times can be short or long depending on the day, time, and how busy Vegas is that week. Early mornings, weekends, and holidays tend to be the most crowded times at the airport. If you have TSA PreCheck and no checked bags, you might get through faster, but it’s never guaranteed. Las Vegas events can cause sudden spikes in passenger volume, so planning extra time is smart. Airlines still recommend arriving early even if you’ve flown from here before. Giving yourself a buffer helps avoid stress if lines move slower than expected.
