Yes, she's the one, Phoebe, in the old safety video (now they have a new safety video I think). I have her in J in a couple of my flights a few months ago, and she's great !! very friendly and great service. She's surprised that I recognized that she's the one from the video (but I think it's quite obvious...) At that time she was already wearing the purple uniform (somewhat more senior?) - so I believe this video (and of course also the safety video) was produced quite a while ago...
