As others have said ,I don't care who I fly with, as I have flown with quite a few females who are more efficient at their occupation than some of the males I have flown with.(not to mention easier on the optic nerve!)
In the past a female pilot may have been a novelty,and having spoken to pilots who flew many of the older airline aicraft, this may have been that a certain amount of physical strength was required in certain situations. This is not much of a requirement today.
What I do object to is the attitudes of some airlines, through political correctness/ minority views on equal opportunity, or whatever you want to call it, not giving the best candidates, regardless of gender, positions available.
They try to deny this happens, but I know at least one Australian airline (with white and red aircraft), that used to contact female pilots who had not applied to them, and ask them why they had not applied and when they were going to apply. This comes from pilots who have been contacted.
Male pilots have never been contacted and asked the same questions!
