Terminal A at Charlotte Douglas International Airport (CLT) is home to Frontier Airlines. The Frontier Airlines CLT Terminal is devoted to low-cost airlines, and its gates are positioned for easy boarding and short walking distances. TSA security checks, quick check-in counters, and basic amenities like vending machines and restrooms are all things that travelers flying with Frontier can anticipate. Although CLT's Terminal A is more efficient than other terminals, there aren't many options for dining and shopping. Before heading to their gate, travelers have the option to visit the main terminal for a wider selection of food and shopping options for increased convenience.
