No not about sexiness for me. I'm gay and most UA crew are female. It's about attitude, rudeness, and safety. I always say please , thank you, hello etc. to all UA crew, and more often than not the more senior crew ignores me or is are outright rude. I know passengers are often hard to deal with too, but sometimes you get back what you give. I just think UA should mix up the crews more - might make it more congenial.
