BA292 (IAD to LHR) yesterday 777 J. Pre-flight greeting from the CSM then during the flight always addressed by name and a cheery goodbye from the cabin crew again using our name.
I suspect all the personal interaction was driven by the minor DYKWIA 'celebrity' in 12D (we were in 11EF) who clearly expected recognition and special service from the crew. Needless to say no CSM greeting nor address by name for her or the PA/Assistant in 12E who had to carry an array of oversize bags.
I assume she was expecting to snag a window seat but with the cabin full and no status no chance as most of the window seats had been grabbed long go.
