UK is out of the question. If you call WP to have your address changed to UK address, chances are that your Northwest WP account will be converted to KLM FD account.
I second this. I wanted to have my address of record changed from ATL to BOM just for the few months that I will be in India next year, but was told that I would have to start from scratch as a KLM FD member and that my elite status doesn't carry over, even though my miles do.
Evidently, India is a KLM market under their agreement, even though NW has more flights here than KL does.
