I love, love, LOVE going out on my overnights with gay FA's. We get to enjoy the scenery together and they keep the slimeballs away from me.
My favorite FA is as married as he can get to a TSA guy. He tells me that when a hot guy walks through security, he shouts, "Man check!"
I think Spira is right about the friendly, outgoing, customer service aspects of the job. Seems like every homosexual I know (even the "not obvious ones") is friendly, outgoing, charming, and instantly endearing. Must be why the pax absolutely LOVE them!
