Well maybe I should rephrase what I said. It seems (more than likely, after reading the responses) that my luck seems to be what's shot here.
I can never get availability to use the upgrade certs to begin with. I even got denied today from using the 10% off coupon that was in my old Select enrollment kit for NER140 due to a lack of inventory.
That was conflicting to what the reservation agent told me on the phone, but I just let it go.
My luck just stinks.
