Folks,
thanks to all who responded - I guess if ABCXYZ Airlines did East Midlands-BWI for £30 return I would have picked up on it, but if you don't ask you don't get.
Looks like BA to BWI it is, but I'll try the dial-a-flight thing. Mind you, it would have to be a bl00dy big saving on Virgin to get me into Dulles.
