For example: If you were a reservist activated to active duty last year, NW will hold your elite status for 2004.
In this case you have a good reason and NW would expect that your flying will start up again once you are back to work.
Always worth asking!
On another note, I missed plat by 5000 miles. Any promo to go from Gold to Plat?? Last year I was 5000 short of gold and they had a promo to make gold in the first two months of 2003.
