That information would have been known to the gate agent(s) as jumpseaters would have required a cockpit pass or nonrevenue ticket. FOX News is foxy.
Furthermore, the CVR is a continuous 30 minute loop tape, the airplane was airborne longer than that. Unless CVR power was interrupted, conversations recorded on the ground would not have been available at the time of the crash and at the end of the recording.
