I think it's a bit harsh to critise Albinoni for mentioning her gender.
She isn't looking for a pilot to fly her around. She's looking for a flying friend.
Say what you like about political correctness, but people tend to form friendships better with those that they have most in common with, and by and large, people tend to form friendships with those of their own sex. Therefore that information seems important.
I think political correctness is gone too far when someone can't volunteer information about their sex.
