A passenger terminal AI system automatically connects with messaging apps on passenger smartphones over a wireless network when passengers enter the terminal. This creates a communication link between the server and each smartphone. When the passenger enters the terminal, the AI system identifies the passenger by facial recognition software or by tracked passenger transactions at the terminal, providing passenger identity. Passenger browser history information and travel information is retrieved from the smartphone. Passenger location is identified and tracked. The server provides the passenger's smart phone, via the messaging app, with 100 personalized messages related to possible purchase by the passenger of travel and other services, located in the terminal and elsewhere, based in part on the retrieved information. The server provides the passenger with terminal schedule and gate information, and also operates with service providers to meet the passenger's desired services.
