Passengers flying with Frontier Airlines LAS Terminal are encouraged to check in online or through the airline’s mobile app for a faster process. For those needing assistance, check-in counters are available inside Terminal 3. It is recommended that travelers arrive at least two hours before their flight to allow enough time for check-in, baggage drop-off, and security screening. After clearing security, passengers proceed to their assigned gate within Concourse E.
