How delays work at LAS

A ground stop holds flights bound for LAS at their origin airports. A ground delay program spaces arrivals out so the airport is not overloaded. Departure and arrival delay messages describe the average wait the FAA expects. None of these tell you whether your own flight is late, so always check your airline as well.

Local tips

Because the airport is close to the Strip, the ride to your hotel can be done in a few minutes. Do not pay for a premium transfer unless you need it.
If you are flying Southwest, you will most likely use Terminal 1.
Summer heat can cause some regional jet restrictions; check your airline if you are flying in the hottest part of the day.
