ACE - BLK stopped at FAO to refuel a couple of weeks ago. If the 733s are more than capable of this route, how come pax have been notified of a schedule change, depending on the load/wind, and the inbound is showing as 5hrs -55min?
If it was tech problem, it must have occurred early in flight, as it took a different flight path to usual, before it had finished crossing the English channel.
