When I initially tried to enter a SC this morning, the dragon tried to tell me that my SC membership had expired yesterday. Note that the boarding pass that I printed yesterday said Diamond Elite Plus SkyClub but it would not scan properly. When they investigated further, the agents could easily see that I had requalified as DM long ago but my SC expiration date shows February 29, 2012, which is what I see on my current membership card or in the SC portion of delta.dumb as it tries to sell me a membership now. However, don't worry as the description of 2012 DM benefits clearly includes SC memberships. At the DTW South SC, the theory currently is that my purchase of five gift day passes in December 2010 did something strange to my account. There's no question of access via two AmEx cards if necessary, but I obviously want to straighten this out before traveling overseas and before being caught in IROPs. It seems to be a very strange glitch. In MSP earlier today, there was even talk of whether I was the first DM that had been seen this morning and how many others might be affected.
