Notfred, its incredibly simple, the airline has a dispatch organisation, the pilot requests the fuel load needed, or dispatch works it out, the fuel is loaded, the flight plan filed, the clearance is issued and away the flight goes, HOWEVER, its a good idea for the aircraft to have electrical power so they can use the radio, if not use a cell phone, on top of this the operator should have enough funds to pay for the fuel! and a pilot capable of clearly notifying dispatch and ATC, the inquiry will we hope see just how many of these actions were done by the crew/dispatch/management, somehow I suspect that we are about to see the usual bull being spouted by various members of Transat!
