A communications system is for an aircraft carrying at least some personnel having PEDs, and the communications system may include a ground-based communications network, and a satellite-based communications network. The system may include at least one access point in the aircraft for providing a wireless local area network (WLAN) within the aircraft to receive a web content request from a given PED and transmit corresponding web content to the given PED. An air-to-ground communications device in the aircraft may cooperate with the at least one access point for sending the web content request to the ground-based communications network defining a return link. Further, a satellite communications device in the aircraft may cooperate with the at least one access point for receiving the corresponding web content from the satellite-based communications network defining a forward link.
