Chicago O’Hare International Airport’s Terminal 5 is home to the Frontier Airlines ORD Terminal Despite being primarily used for international flights, this terminal facilitates Frontier’s domestic operations by providing easy access to gates, contemporary security facilities, and convenient check-in counters. The pre-flight experience is improved by Terminal 5’s array of facilities, which include free Wi-Fi, shopping, and dining options. The Airport Transit System (ATS), which connects all terminals and parking facilities, provides accessible transportation within the terminal for added convenience. It is recommended that travelers arrive early in order to give themselves enough time for boarding, security, and check-in.
