Rumours that MAN is one of 3 airports currently in the running for a new transit flight...
Its in the very early stages, and purely rumours at the moment, the carrier has served Manchester before, and is not Biman Bangladesh.
The other 2 airports also being studied also have a strong case, so will be a case of wait and see. The route may not even go ahead at all, they are merely in the planning stages to see if such a route would be viable (probably won't be, a similar route by them has failed before and Manchester didn't work for them last time).
Seems to be a new age of transit flights coming about, with Biman at BHX and Ethiopian at Dublin.
