Terminal" typically refers to an airport terminal or a bus terminal, so I'm assuming that's what you're referring to.

If that's the case, the Frontier terminal in Las Vegas is located at the McCarran International Airport. Frontier Airlines is a low-cost carrier that operates out of Terminal 3 (T3) at McCarran Airport. The terminal is modern and spacious, offering a variety of amenities such as restaurants, shops, and free Wi-Fi for passengers.
