Cheap flight for someone looking to get across the pond later this summer. A few cheap fares from Condor from MIA to MAN. Dates are not super flexible but you can play around (I think I saw something for 408 if you leave 7/3). The price is on the actual Condor website and wasn't pricing on some of the other OTAs. Appears to be operated by Thomas Cook.

I haven't flown either so buyer beware.
