Just got a salubrious text from my sister - straight from WT to CW on a long haul out of LHR. Her best friend is a CSM and left a note for the crew. It worked apparently, as when my sister (she has BA Blue) boarded, the CSD discreetly walked her and her mother-in-law to seats in CW. It was a special occasion, so that was lovely for them. Great when it happens to family, although the CSM apparently said it was a rare occurrence.
Did anyone complain to BA about it?
