"Manchester City Airport"?
I can call my house a castle but it doesn't mean that William & Kate will be popping in for tea and biscuits anytime soon ... Manchester/Barton is a grass aerodrome ... "Airport" my ass!!!
But ... be respectful enough to answer jabird's question(s), what routes from Sheffield City, what aircraft types and what operators? ... And without changing the topic of conversation to a grass field somewhere close to Manchester!
