So how will airside transfer for LHR-MAN-XXX and back again where XXX is international from T2 work in this new world. Last time I did it , although the website said it was possible, it was a right pain requiring lots of asking of staff who hadn't a clue , before finally giving up and going out landside and back in again. Would be nice if it had become easier since domestic airside transfer from/to BA appears to have become impossible.
