The cabin crew on the last flight when I was upgraded certainly knew that I had and also the reason why. It was a BA flight from PER to LHR (when they still had BA11 & 12) and was on the SIN-LHR sector. I know they knew because I was taken down and introduced to them as "This is the lady you have been hearing about" They were brilliant. I couldn't have been better looked after and YES, I did write a letter of appreciation.
