A communications system for an aircraft carrying personnel having personal electronic devices (PEDs) includes a wireless access device in the aircraft for the PEDs, and an aircraft server in the aircraft cooperating with the wireless access device for determining airborne validation of a ground server address entered via a corresponding PED. An air-to-ground transceiver in the aircraft cooperates with the aircraft server for communicating over an air-to-ground interface the airborne validated ground server address. A ground server on the ground receives the airborne validated ground server address over the air-to-ground interface, determines ground validation of the airborne validated ground server address, and provides ground access for the corresponding PED for which the entered ground server address has both airborne and ground validation.
