Regulating Stansted is surely a good thing overall. I know it's bad from Stansted's point of view but I don't see how it restricts growth. As Stansted is an airport for LCC's, then surely the owner wouldn't want to overcharge as it wouldn't interest LCC's.
I welcome to news, the lower Stansted is flogged for the better. It means that a new owner will have more to spend on future investments or if it prefers, allows it to reduce charges to airlines to attract more traffic that way and since MAG and the Malaysians are still committed, they clearly are not put off by regulation, suggesting that increasing charges were not their intentions. As for BAA or whatever they call themselves now, the worse it turns out for them, the better. They are a selfish, biased and a complete rip-off to their valuable customers (airlines and passengers). In my opinion, it's pay back time for them and they deserve evey single bit of bad news they get.
