While we are on about the difference between EF and WW crews, etc., this may be entirely coincidental, but the worst examples I have experienced of poor service, downright rudeness, and total PSR/CSD disinterest have been to and from NRT (apart from the Japanese crew members). Given that despite BA's best efforts so far, NRT trips still seem to get crewed by certain "connected" BASSA types (allegedly) to earn the big money, this would seem to point very specifically at where the performance issues lie within the CC community.
