your above comments are slightly wrong. However do not believe me, just ask any premium pax who fly from both bases, or even some of our 777 FC who do the same. Taking nothing from my LGW colleagues, the lack of hands DOES make a big difference in-flight.
Maybe a lack of experience at first but this is fast changing - don't kid yourself. Despite your protestation to the contrary there is an implication here that not only do you see your service at fortress Heathrow as being superior you also think it better than other airlines who already survive with less crew and working SCCM's - I am sorry to say that despite BA generally being excellent onboard - you are not alone.
