No its just the one flight, EK17/18.
LHR has only just gone double daily with A380s, so doubt that MAN would get 2 in a day for another 1-2 years at the bare minimum.
Just for the Nay sayers who think F wont work from MAN, it seems there are only a couple of F seats left on the inbounds, still quite a few on the outbounds, but may take time for the people comming in F on the EK17 to go back out again on the EK18.
