A communications system for an aircraft carrying at least some personnel having personal electronic devices (PEDs) for wireless data communications outside the aircraft includes a satellite-based communications network that includes a plurality of satellites, at least one access point in the aircraft for providing a wireless local area network (WLAN) for data communications with the PEDs, and a satellite transceiver in the aircraft cooperating with the at least one access point for data communications with the satellite-based communications network to the PEDs. At least one network selection controller is for selecting a satellite among the plurality of satellites so that data communications is sent to the PEDs through the satellite transceiver based on a needed channel capacity of the data communications to be sent.
