Thanks everyone for the replies to my questions. I have been looking at these and trying to make some shape of it all.
It looks like a problem if I stick with KLM as they will be switching to NW out of AMS which means a DC10. One question, if I book with KLM and fly NW 'Metal' do I still continue to rake up the bonus points with KLM and what would the chances of an operational upgrade be like?
Thanks for the thoughts, keep them coming and Ill have a look at the US Air this evening.
