True, but FR utilise their aeroplanes for longer than 12 hours per day and we are going up and down like a wh*res drawers burning fuel at inefficient lower levels for a longer period during that 12 hours + than the 747 heading to LAX.
True about the fuel burn. But with an average of 6 sectors per plane per day. that is a potential of 1134 pax generating fairly decent revenue too... versus one 12 hour sector for the whale carrying about 400 pax.
