I know the change is controversial, but I'm broadly for it. The BAC is over-powered in that is so good for so long if used correctly, when we know in real life it was never a keeper in such a way.
What will be interesting is how people's strategies change. There is no like for like alternative. What I expect to see is more large bases, fewer regional airlines, the 737 becoming even more precious, along with the DC-9, and the NAMC becoming the go to plane for regional carriers.
I think a better solution to the problem however might be a new class of plane, and a new class of base size and a new class of airport size. We currently have 4 classes. Small, medium, large and extra large. I think there the BAC, the Fokker 100 and the E190 sit in a field all of their own, that could do with a category in between the current "medium" and "large" categories.
