I rmember watching car loads of Jamaican ex-pats arriving to check-in at BHX for a short series of charters to Kingston flown by British Midland in, I believe, the late 1970. Families all dressed in Sunday best, dad in smart suite with trilby, mum in smart dress, and the kids dressed up to the nines.
How they must have felt stepping out into the heat in Kingston heaven only knows - but at least in those days people treated flying, and presumably their fellow passengers and cabin staff with some respect.
