Originally posted by MarkJerling Air NZ staff at LAX are, indeed, fantastic to deal with. But, most New Zealanders now prefer to avoid the LAX experience entirely, as transit through other airports (in other countries) is so much easier.
Avoiding LAX as an alien traveller (to US authorities) is a good strategy, in my experience, particularly after the 14 hour flight from Sydney. My last experience there was prior to 2001, too. I can only imagine it's got worse since then.
I've done the Melbourne to London many times over a long period. That's never a great deal of fun, either, but I've found I can manage 12 hours sleep over the journey, with chemical assistance (of the prescription variety, naturally). Business and First Class used to help, but retirement and paying your own way has reined that in.
I have to add that, in Economy Class, the most comfortable flight on that route that I've experienced was in an Air France A380.
