Frontier Airlines is based in Terminal 3 at Harry Reid International Airport, which was formerly known as McCarran International. Frontier Airlines LAS Terminal is a very modern and large terminal that has the capacity to service both domestic and international flights and primarily caters to low-cost airlines such as Frontier and a couple of others. The terminal was designed with efficiency in mind; the check-in counters and self-service kiosks of Frontier are found in the east wing. This helps passengers check in quickly, print their boarding passes, and proceed directly to security.
