None of this explains why Aust ATC flow control remains the worst I have seen anywhere in the world.
25 years of operating to LAX, LHR, FRA and assorted other dearly departed destinations with very complex airspace requirements and with shedloads more traffic than Syd, and rarely are we dicked around as much as we are in australia.
Sorry to the ATCO's, it may well not be your fault (could be systemic I realise), but there is another side to the coin.
Oh, and if the 94 is such a cash cow why arent Delta, American and Virgin Blue flying mel-lax also ?
