This sillyness has been dumped on the industry and passengers for 20 years now.
It beggars belief that a 3rd party (now called CTMS) can dictate the commercial arrangements between 2 other parties.
Simply because a so called service provider (AirServices) cannot handle the available or planned air traffic at, in this case Sydney, the airlines and their passengers are restricted in conducting their normal business.
Add to this the artificial non availability of 7 out of 24 hours due to a politically motivated 'curfew' and one would have to wonder whether doing business or anything else was worth the hassle of going to Sydney.
Sydney, the 1st airport to slide ingloriously back into the 3rd world.
