For a typical domestic flight out of LAS, plan to reach the airport 72–92 minutes before departure. The hour you fly moves that number more than anything else.

Representative arrive-by times at LAS
Each row is worked out for a domestic flight leaving at that hour, using the standard (non-PreCheck) security lane. “Before departure” is how far ahead of your departure time to be at the airport. Add your own travel time to get there.
| Departure | Arrive By | Before Departure |
|---|---|---|
| 6:00 AM | 4:46 AM | 74 min |
| 9:00 AM | 7:28 AM | 92 min |
| 12:00 PM | 10:33 AM | 87 min |
| 3:00 PM | 1:44 PM | 76 min |
| 6:00 PM | 4:40 PM | 80 min |
| 9:00 PM | 7:48 PM | 72 min |
These assume no checked bag and the standard security lane. A checked bag, an international route, or PreCheck and CLEAR all shift the number. Your exact flight accounts for each of them.

How these times are built
BoardFlight works backward through each step of your journey: curb to check-in, bag drop, security, and the walk to your gate. Every step is modeled for LAS and the hour you fly, then combined into a single arrive-by time. The plan is built for a busy day rather than an average one, so a normal slow morning has headroom without sending you absurdly early.
It is honest about what it knows. Parts of a flight’s plan that come from a default rather than airport data are marked as estimates. An unconfirmed delay never makes the plan riskier, because a posted delay often gets rolled back. The arrive-by time stays anchored to the scheduled departure.
Common questions about LAS
How early should I get to LAS for a domestic flight?
With no checked bag and the standard security lane, BoardFlight's representative times for LAS run from 72 to 92 minutes before departure, depending on the hour you fly. A checked bag, an international route, or PreCheck and CLEAR change that number.
Is 2 hours enough at LAS?
For a domestic flight, usually yes. BoardFlight's representative times for LAS run 72 to 92 minutes before departure with a carry-on only, and 98 to 118 minutes with a checked bag, depending on the hour you fly. Your terminal, your lane and an unusually busy day can change that, and your airline's own check-in and boarding deadlines always come first.
How much earlier should I get to LAS with a checked bag?
Plan on 98 to 118 minutes before a domestic departure with one checked bag, compared with 72 to 92 minutes with a carry-on only, based on BoardFlight's representative times for LAS. The difference is the time to reach the counter and drop the bag. Your airline also sets a cutoff for checking bags before departure, so check it before you go.
How early should I get to LAS with TSA PreCheck?
With TSA PreCheck, BoardFlight's representative times for LAS run 67 to 81 minutes before a domestic departure, compared with 72 to 92 minutes in the standard lane (no checked bag). PreCheck shortens the security step; the walk to your gate and any bag drop stay the same.
How early should I get to LAS for an international flight?
Plan on more time than for a domestic flight. For an international departure from LAS, BoardFlight's representative times run 82 to 102 minutes before departure with no checked bag in the standard lane, depending on the hour. Airlines set earlier check-in and gate deadlines for international flights, and those come first, so check yours before you leave.
