striparella I am sorry to hear that you have had this sort of flight deck spouse on your flights.
I was the wife of a captain and, on the few trips I managed to go on, I was always extremely courteous and appreciative to the cabin crew.
It was (sometimes) my experience that cabin crew were not very nice to me to begin with...........perhaps they had some previous bad experience with other captains' wives, as you describe. I usually managed to win most of them round with my pleasant, co-operative, considerate and friendly manner, but it would have been easy to be put off by their initial attitude.
It's a chicken and egg situation really. Neither person should pre-judge someone just because of who they are.
I agree with
apaddyinuk though.........it is a massive and unfair generalisation to say that
all flight deck spouses are like this, just because the ones you have dealt with have not been very nice.
