Thanks for that guys,
I did fly Air New Zealand both in Biz from London to Hong Kong and then coach from LAX to MEL. To be fair, their coach was great, the seat had a good recline and the food was pretty decent, so no real complaints.
That said, last time I flew US Air Envoy was roughly 3 years ago and that was also enjoyable. I did find the seat very comfortable and the food was always nice.
I know 3 years is a long time for an airline, so I dont know how the envoy is these days. If I do go US Air, I will make sure I dont fly the 757 cause that is a total joke.
Thanks for the imput guys^
