I can answer for CU as I study in B'ham and move back there in a months time. It's a massive detour, you can get from city centre to airport terminal in 10 mins thanks to virgin trains, it takes 1hour 42 mins to get to EMA via a combination of rail and bus. This xmas I think I'll get the train to Warrington were my sister works and fly home with be from MAN! Hope BE grasps the opportunity while it can!
