I'm not sure whether she had implants, but on a short United flight from Chicago to a smaller midwestern city a few days ago there was an older stewardess (maybe 50 or 60-something) who'd had some pretty intense plastic surgery on her face. Definitely the most plastic stewardess I've come across.
Maybe someone else will have her on another short flight out of Chicago, if she regularly flies those routes. It sounded to me like she might have had an accent (French or Spanish, possibly), she was on the short side, and I seem to remember that she had light-brown or dirty-blonde hair. Toward the end of the flight she also put on what I thought was Givenchy perfume.
