I see that AIR has now rescheduled 2000 flights for next year. They say 90% will leave within sixty minutes of original schedule (that's probably just about as good as flights that haven't been rescheduled:p).
But on a more serious note, they say that 10% of these flights, presumably international, have been rescheduled for a different date - no mention of compensation for the inconvenienced passengers (extra accommodation, food, ground transport, extra days off work, missed activity bookings etc). AIR seems to think they will get away with this but in reality they are on the hook for damages under the Civil Aviation Act up to $8800 per pax whether they like it or not.
So let's say the average cost to pax is $1500 and 10% of 2000 planes are affected, say 100 pax per plane, I think AIR is looking at some serious compensation - circa $30m. And the extra damage to reputation
