welcome to FT!

I suggest you write a letter to NWA, where you explain your case, ask them to waive the fees paid when miles are redeposited. You might want to enclose all supporting documentation.

Per http://www.nwa.com/plan/comm12.html send the letter to
Northwest Airlines
Customer Care
PO Box 1908
Minot, ND 58702
Phone: 701-420-6282
Fax: 651-367-8459

I have to believe that if NWA can do Active Military WorldPerks® Elite Extension then they can favorably respond to your request.
