Operating out of Terminal 1, which is mostly utilized by domestic airlines, is Frontier Airlines CLT Terminal at Charlotte Douglas International Airport (CLT). Although Frontier Airlines is a low-cost airline, it provides affordable travel alternatives, but it charges extra for amenities like carry-ons, checked baggage, and seat selection. In order to check in, which can be done online or at self-service kiosks, travelers should come early. Travelers are advised to study the airline’s regulations in advance as baggage fees differ based on weight and size. Passengers must follow TSA rules and present appropriate identification for security. Frontier wants to offer a simple, cost-effective solution.
