Thiught I would share a update, as I was expecting Monday evening the flight was cancelled on MMB, called BA and after some discussion and explaining EU261 was able to rebook my friend on a Qatar flight. Told once back his connection in MAN can ask for a refund since he would land at 2pm and next BA flight to MAN is next morning so will pick him up and expact some office to pull me to the side on the M25 asking what am I doing. For FYI seems the flight was 15 days away and all BA flights in April to ISB are cancelled.
