straitman,
If a flight is cancelled 30 min before departure, I agree entirely that there is no need to call/contact me, as I should be at the airport.
However, in the case of 60 min, I disagree. Given I had checked in using OLCI and had carry on luggage only, I see no reason to be at the airport any earlier than 30 min prior to either a DJ or QF flight when QF and DJ do not commence boarding until 20 min prior to the flight (if they're running on time). One of the key reasons for paying a higher price to fly DJ or QF is the convenience of not having to be at the airport at least an hour before a flight and then sitting around waiting at the airport. I have never known a fllight to leave early!
Had I been called or sms'd and advised the flight had been cancelled and the next available flight was 4 hours later, I wouldn't have left home. Even if I was on my way, I could have turned back, rather than having parked the car and been stuck at the airport.
As far as I am concerned, I paid to fly on a particular flight (contractual arrangement) and if, for whatever reason DJ cannot provide the service I paid for, they have broken their contract and should go out of their way to at the very least contact me and make alternative arrangements.
I acknowledge that if I was too late that I would miss the fllight, but that was not the case (I was at the gates 15 min. before the flight, which would normally mean they would be half way through boarding).
Will definitely make sure I check the board in future though!
