Many years ago flying with AF on a Trans Atlantic flight (707, it was as I say sometime ago) I was a little surprised to see a bottle of Red wine go into the flight deck for the crew with their meals. When I mentioned it to cabin crew they appeared quite concerned that I was concerned about it, it was "natural on such a long flight". Thought this practice had gone, but on a trip out to the Far East I was told of similar thing by a young women who had seen the same on an AF Jumbo in the 1980,s, I would assume this practice has now stopped.
