Why couldn't they have done this when I was doing twice weekly trips from ORD to CVG. Try as I might, I was almost never able to get on the Mainline flights and was always on the AWAC flights. I can't count the number of times last year that I was stuck at ORD because the AWAC flight had been cancelled or delayed enough that it was cancelled anyway.
Thankfully, I've moved out of the CVG area and don't have to deal with them. I AM very happy for those that will have this headache go away though.
