I don't think I am personally a "gamer" by most people's definition, and while several of the current changes won't hurt me at all, I did like the ability to SDC for flexibility. To my best recollection, I never used it to obtain a lower fare. The reasons I didn't do that were usually simple and logical. First, I could never count on availabilty on any different flight as most of us know from experience that IROPs can zero out availabilty for days on some routes. Second, there is a substantial risk to losing an upgrade when utilizing SDC on a coach fare. Now on JAX-ATL, that really isn't a problem, but in the case of JFK-SLC, I do start to care about that upgrade. So, forgive me if I think that the amount of "gaming" to a lower fare via SDC is really that problematic to DL. I think one would be short sighted not to realize where DL is going with all of this. While I may not be the main target of DL's cuts to its FFer program right now, if these changes are accepted by the general medallion population without much blowback, then I am probably in that next level to be hit. For those who are much higher HVCs, you'll probably be fine, but then again...
