EI-BUD, my quote wasn't in response to you.
BMED is LHR, not LGW (it's personal opinion) but the LGW handling is better than LHR in my experience when it comes to BA, may come down to the size of the operation but that's my view.
I've flown from the South before numerous times from LGW on a number of different airlines and the handling isn't bad, often very good but as an overall package I believe flying from the North at LGW and being handled in the terminal by BA staff and on the ramp is better than flying from the South and being 'looked after' by a generic ground handler.
