I seem to recall that there was a CTA ruling that disallowed this. OP might want to check on their web site. Real limit is supposed to be gate presence cutoff. Of course they can get the system to do this, but surely gate agents can overrule the system. But then they migt have to cancel someone's upgrade, which the GA might not enjoy too much... Anyway, this might call for (1) checking and if I am correct about the CTA, remind Customer Solutions about it. And if going nowhere, this is a case of doing the work of going to the CTA again, not so much for compensation but for the principle. That rule makes no sense and cannot possibly be enforceable; MCT is 100% an internal airline matter with no bearing on the customer. This is an abuse.
