MAN is a far better airport. It is also one that I avoid as much as possible simply because getting there from North Leeds is a nightmare.
You can dress it up all you like but I would explore all other avenues than use it. It is great for the residents of Manchester, Chesire and Merseyside. It is not great for the people of Yorkshire unless they are right on the M62.
I think BA recognised that fact when they started this route and contrary to popular belief pax figures are rising steadily. 4 rtn flts a day was always too many - what routes ever get that? But having generated a customer base this Winter and shown some commitment by moving it to T5 with 3 per dya I am hopeful of a good Summer for the route.
