Me too. I was a regular on the LHR-GLA-LHR & LHR-MAN-LHR routes but look at them now
Based in the Middle East since last summer I even tried to include them in my schedules to AUH or DXB via AMM or CAI or some other (weird) place but no, the schedules just don't work. All of my business has gone to VS, GF & (GULP) BA.
I love DC but have stopped earning on them since last September & still have c200k miles to burn. I most likely will not atempt to qualify again for DC*A Gold...sigh
