CJ, it's better you not get into an argument about doctors and hypocratic oaths here. This is WAY off topic (apologies to all), but if you were as close to a doctor as I am and understood anything about the current medical system, you would know why GPs often don't run on time and patients wait for correspondingly long periods.
Back on topic....
QF has its fair share of problems, but flights to & from LAX (and especially via MEL) are a particularly bad bunch to pick on, for many & various reasons. I know for a fact that some aspects of the LAX service are getting attention from VERY high levels of QF management (ie, about as high as you can go), but they are limited by a lot of factors, including unions, overseas airport contractors, overseas regulations, etc, etc. However, while
VB may have nice cabin crew, it is certainly no 'angel' in the service department (and
VB doesn't fly to LAX, so what the heck would it know anyway?).
