Went with my younger daughter a few years ago to buy herself a new car. I was only there because I got a discount on new cars of that make.
But would the salesman talk to her - would he heck! He patronised and ignored her until she said "C'mon Dad, let's go where they'll sell ME a car."
We did, too.
Never seen anything like that in flying.
Maybe the statistics are skewed, but I seem to know a lot of female pilots.
