At the Frontier terminal Las Vegas, check-in counters are located on Level 2 of Terminal 3. Frontier encourages passengers to check in online or via their mobile app to save time, but if you need assistance or are dropping off checked baggage, the staffed counters and kiosks are available.

Baggage drop-off areas are clearly marked, and the airline recommends arriving at least 2 hours prior to domestic flights and 3 hours before international departures to ensure a smooth check-in and security process.
