I always thought that part of BA’s USP was the smugness of the crew and the feeling of smugness they imparted to those pax who wanted to partake in that feeling of superiority? I once flew a 1:20 sector with Heathrow’s Favourite and the FO managed to squeeze in five(5) cloyingly condescending PAs which I thought was mightily impressive!
As for the uniform - I am surprised to still see differences between male and female staff in this age of equality and inclusivity. Why are they different if they are all the same these days?
