Frontier Airlines operates out of Terminal A at Charlotte Douglas International Airport (CLT). This Frontier Airlines CLT Terminal is a destination for low-cost flights because of its well-located gates, which allow for easy boarding and minimal walking distances. Travelers flying with Frontier enjoy TSA security checks, expedited check-in desks, and standard amenities like toilets and vending machines. Although Terminal A at CLT is more efficient than other terminals, there aren’t many dining or shopping options. For added convenience, passengers can visit the main terminal before going to their gate to choose from a greater variety of restaurants and shopping alternatives.
