Roy,
Perhaps this thread is an example of why this should be restricted to professional pilots only - verified by their licence number.
In this case, where no reason had been given as to the cause of the delay, I think a thread like this is invaluable to all in order to get across both sides of the story. There will always be the drum beaters but most of the passengers I fly are grateful for information as ground handling staff are told not to give it out many times. The reason for this is that the airport staff do not want delays going down to them and would like to pass it on to the crew. These delay codes are collated data and used, many times, to set servicing prices at airports.
