My local airport is Coventry, hence my username, and, from a flyer's point of view, to be honest I am happy that there are only the smaller aircraft using it. These smaller aircraft mean that turn around times are that much quicker: less passengers = less time for embarking and disembarking, and less time to load and unload the bags.
Don't get me wrong, I would love to see more 757s use the airport, which they have done several times when fully loaded (moreover I would love to be in a 757 from Coventry), however, I think that in such circumstances, the airlines need to be practical about their resources.
