I appreciate you have a downer on anywhere that isn't MAN, but you'll need to find a better example than that
Yes, I have a real downer on Manchester, regularly using Liverpool to visit relatives in STOCKPORT and using Leeds when my daughter lived there.
Jet2 may well have to use both airports to make the ski flights profitable but, in the context of the thread, that doesn't say much for the market in Leeds which needs the traffic more than Manchester.
