Lol. Dig at them not intended. Both our ATCOs and BuMET forecasters do the best job they can with the cards they've been dealt.
LAX doesn't get the mix of jets/ lighties that Sydney does. Yes, they get lighties. They don't get as many of them. They've also got a better airspace structure and more tarmac to move them. Same applies to LHR, FRA, NRT, etc.
As for weather forecasting, our environment is just crappy. I don't envy them the job. Cry wolf with FG in PER too often and the airlines are bleating about carrying fuel for when it wasn't needed. Get it wrong just once and don't forecast it and you've got angry pilots bleating about not having enough fuel.
