I am about 70-80% with my Gold Status.... since November 2004

DCA-CHI 4 for 4
DCA-ASE (on NW) 3 for 4
DCA-SAN 2 for 2

Its worth it to me to fly a bit more to keep the status...

Its all about the time of day, day of the week and where from flying from and to..

Tougher times will be between 3 and 7pm - M,T,Thur from a major city/hub - fly from Hub to Hub - good luck! Saturdays, Sunday, Wednesday's I notice are easier. A special event in that city will also lessen your chances...
