I am interested in what you all tell your passengers when you cop one of these delays. Do you blame it on ATC or do you explain to them the reason for the delay is that demand for landing (or taxy) slots exceeds the supply and there is nothing that ATC/Qantas/Skywest/Skippers/Virgin etc can do about it. The only way it will improve is the construction of another runway? For those operating FIFO do you tell Fortescue/BHP/Woodside etc that the reason why there staff are 30mins late is because there is not enough capacity or do you blame it on ATC.
If not, then start doing so because the only way it is going to change is if the public and the mining companies which pays all our bills start making noise about it.
