I have to say, I have flown with nothing but lovely crews recently. Sometimes people come out for a drink, sometimes they dont - twas ever thus.
I am pleasant, friendly and respectful to all crew I fly with, regardless of some of the initial frostiness we can receive - thankfully rare.
I fly on the 777, so will fly with MF, WW and SFLGW crews. It will be interesting to compare. IMHO there is very little in service quality between LHR and LGW. The best crews at LHR are poetry in motion, but with the current dispute, there is much less willingness to go the extra mile.
One thing I think we all can agree on, is that we ALL want this over with, so that BA can become the world beater we all want it to.
