DM Card received a few weeks ago good thru Feb 2013. Included JWD certs, HOOU coupons, etc.
Also SO's gifted GM card arrived and also good through Feb 2013. No certs or coupons.
SkyClub card arrived and updated through mid-2013 reflecting leftover months as well.
Guessing that DL will not be issuing a mass mailing in late Feb as in previous years.
