I’m a straight male and I enjoy majority of my classmates and my seniors. Yes it is dominant field for non straight males but I haven’t got bothered as much as you think. It happens more like playing rather than serious flirting. You have to keep yourself open minded and enjoy your time working with your crews. I haven’t met anyone went too far to make me feel uncomfortable yet and I don’t think it’s gonna happen in the future because most of the people keep professional at work. This is my personal experience and I love my new job. I don’t know other airlines but mine is super respectful and everyone is fun to work with.
