Air NZ might go both ways now (oo-er) but luggage allowance is still more than double via USA (70kgs) than Asia (25gs) so I can take a bike, and it's less time in total and I know the way now !
It's not the fee than concerns me, I went through LAX just after the last attempt to introduce something like this the queues were monumental as opposed to the usual humungous. In the end they had to let the Air NZ passengers through without processing us in or out as the plane was ready and waiting an we would have missed our take-off slot. Its a joke anyway you walk down a corridor, queue for hours, hand over a piece of paper, then walk back through the customs desk, give the piece of paper back, and up the same corridor to the same plane.
