IaLTO,

Here's what I did. I used to be with KLM FD while I was still living in Holland. After I moved to the US I immediately opened a WP account and had my FD miles transferred over to my WP which you can do by sending a fax to the DF Helpdesk mentioning that you moved and your new WP number.

They transferred my FD miles at a favorable exchange rate and now I'm Silver Elite. THe good thing is that I still earn miles on discounted tickets flying KLM.
