This is a game, a tactical game like chess, the one with the most slots at LHR takes LHR eventually, if he manoeuvres properly, its about being succesful and getting to the top, by any means possible. Why do you single out LHR, because of the curfew and soo few slots, go complain to the queen.........!
Many airports traffic and airlines are highly unlikely too, but thats why its a GAME. We try mimic reality in some places and excuse other behaviour as not being able to fit a game into reality by opening routes in 1996 to all vacants demand LF's, totally unreal too!!
LHR, limited slots, the last thing you want is 1000 airlines flying there, and you cannot get out with your new ordered 747's etc, because every Tom, d***, Harry and his mother want a route to LHR. Swiftus, you have been around along time, thought you would have given up on this pursuit of F27's, maybe you should try ban then totally from the game, you obviously dont like them, but I am sure alot of aircraft you have operated you dont like either, its a game man, we are only lucky we are still able to call the airports by there real name, if we had to rename them because of infringements laws, it would not mean anything to you if LHR had F27's and was call Circusthrow!
F27s are a means to an end, just like every aircraft and route you fly.
