01Mar2006-28Feb2007 Platinum Elite
01Mar2007-29Feb2008 Silver Elite

I purposely flew fewer miles on NW in 2006 due to its labor thrashing about, so I didn't expect a soft landing with 30K+ EQMs.

My current plan is to credit miles on NW only through 28 Feb when I lose Plat status (in the hopes of an upgrade on those flights), then credit it all on AS Mileage Plan, where I'm an MVP Gold. I get the same seat selection preference as an NW WorldPerks Elite through my AS status, and this will help me requal as AS MVP Gold even faster.

Besides, living in SEA, getting any kind of upgrade as a Silver is, well, long odds. It was tough enough as a Gold and then a Plat.
