Security is provided in a wireless communication system in a moving vehic le, e.g. an aircraft, by requiring user input of one or more security codes for validation before the system permits communication. One code, a security access code (SAC), corresponds to the vehicle travel segment (e.g. flight) and is given to the passenger(s) in transit, e.g. after the aircraft reaches a particular altitude. The second type of possible code, a personal identif ication number (PIN), is given to the passenger after baggage check-in. The PIN code would be correlated to the passenger and/or seat assignment. The us e of either or both codes helps prohibit connectivity for mobile phone hands ets or other wireless devices stored in the cargo bay or in other baggage. P IN use enables associated data systems to report the seat number or location of all parties engaging in wireless communications within the vehicle.
