I'm not sure if Tiger is operating to "schedule" or not, but this incident, and a similar one in Perth, leads me to wonder if the toothless Tiger that is CASA will ever require any Australian airline to make reasonable efforts to operate to a published schedule and to fulfil their responsibilities to passengers.
CASA do not get to make up the rules, which provision within the Civil Aviation Act are you accusing them of not upholding?
