Girlpilot, chill out! Sexy in my opinion is not the same as sexist. I think what the designer means is that the CA's will look more like most do in other airlines instead of looking like grandma's like they do now (no offence BA hosties, you didn't have a choise I know). I agree that sexiness has a lot more to do with who you are than how you look. Just like your professionalism as a pilot has nothing do with wether you're wearing a T-shirt or a uniform dripping with gold. But passengers are sensitive to uniforms. Uniforms bring a message across. The BA uniform right now looks dated and sort of dull. I think a change would be great.
Good luck with your ambitions to become a pilot. It's a great job, no mather what they say!
