I have only had two captains who have made me feel uncomfortable in the cockpit. Surprisingly I do fly with a lot of captains that say I am their first female FO which is shocking to me. I agree that it is no different, I am treated like everyone else, from the pilots. The passengers will always make strange comments. Either "you go girl" or "wow I've never seen a girl before." I made a lot of good female pilot friends at the airlines too.
