In the Airport 1.0 phase, airports focus on capabilities necessary for safe and efficient management of landings, departures, and other aircraft operations. They offer basic passenger services, including check-in, boarding, security, baggage pick-up, and moderate retail, food, and beverage services. Typically, these airports operate in a landlord model, where the airport/landlord provides the real estate, while airlines, concessionaires, and other tenants design and implement their own business environments.
