Well, I've done a fair share of commuting and, while it may sound glamarous, it soon becomes the pits.

I don't care how many lackeys you've got carrying your bags and driving you around, a weekly 10hr+ (and return) quickly becomes a nightmare, even in First.

I can't imagine why anyone would voluntarily subject themselves to a weekly flight from Oz to the UK. Whilst I'll believe that this person exists, I have to wonder about their sanity. LHR-SYD is pretty much 24hrs, so 48hrs return. That's one-third of your week spent (mostly) in a plane. Think of all the things in life you are missing. Wouldn't it make more sense to move or have people come to see you once in a while?
