I agree Manchester airport could not care less about its passengers and the lounges are a disgrace (perhaps not the worst in the world).
You have to wonder about the airlines here because in theory they could ensure that the service meets their customers expectations
Having said that Etihad in Manchester have their own lounge and it has to be one of the best in the world (for a small outpost) with world class customer service and a real personal service and staff who go out of their way to make sure you have all you need.
