We've always had a very well honed ability to look down our antipodean noses at the Yanks and their way of doing aviation but as far as I'm concerned flying commercially within the US airspace system is an absolute joy.
It doesn't matter whether it's the Atco's or the rules politicians set, the end result is the same; it's a pain in the ar$e to deal with them. Compare the way ORD or JFK approach sequences 3 times the amount traffic with the mess SYD makes of it. No wonder we waste so much fuel here.
