I've asked why there have been hold times recently and the agents have told me it's because there are more Diamonds. Apparently the $250K Amex waiver didn't "thin the herd" as they said it would. Prior to last fall, I had to hold only a handful of times, but now it's anywhere from 1 to 11 minutes for me on a regular basis. Seems more likely that they've reduced staff or at least reduced staff allocated to the Diamond line.
