Frontier departs from Terminal 3 at Harry Reid International Airport (LAS). We verified this against the airport's own sources on June 27, 2026 — airlines do move terminals, so we date every check.

Frontier departs from Terminal 3 at Harry Reid International Airport (LAS). Terminal 3 ticketing (Frontier operates a base at LAS); gates in the Concourse D / E area, reached via tram from Terminal 3. Verified June 27, 2026.
Terminal 3. Bag drop usually closes 45 minutes before departure, so build that into your morning.
A few third-party terminal guides (detaileddrivers.com, psswestcoast.com) still list Frontier in Terminal 1, but those pages are stale (they also still list the now-defunct Spirit Airlines). Current Frontier-specific evidence places it in Terminal 3. We confirmed Frontier's current Terminal 3 on June 27, 2026.
Not sure which building that is? See all LAS terminals with the airport map and how to get between them. Then let your Leave-By Time count backward from your flight — today's LAS security wait, your drive, and the walk to your gate — so you leave with room to breathe.
