there have been so many delays/cancellations in QF in the last few month that the printed schedule means nothing. with over 5000 flights a week there have been many changes which are not published. the cost to communicate this to passengers, rebooking on other available carriers at full costs, putting passengers up in hotels around the globe, paying compensation to passengers overseas, etc.etc, runs into tens of millions of dollars. nice on Geoff.
one less 747 and other maintenance issues, one never knows which aircraft arrives/departs. the only good news is the arrival of 2 A332.
