I understand if the airline wants it's F/A:s to be good looking, as it could attract more people traveling with them, but then again, I believe that looks is nothing in an emergency situation, and in many other situations for that matter, that's when experienced F/A:s is important...
Coming to think of it, I wonder if good looking F/A could be a security risk. Let me explain:
A good looking F/A could be a security risk if:
1. She's been hired only because of her looks, and she lacks common sense, experience and the capability of keeping her head cool in situations that might occur on a flight.
2. If there's alcohol being served onboard. Some people (men) feel that if there is a attractive woman in his immediate proximity, and he has alcohol in his blood, those cursed breeding thoughts comes in to his head, which could very well lead to harassments of the F/A. And when he (this alpha male) has no success with his "prayer" he might get upset, and people that are upset could do things that maybe is not so dangerous at a bar, but at 35,000 Ft they might be fatal... Leaving, for instance...
I don't really care whether the F/A is good looking or not, they are there to provide pax with service, and to enhance the chances of the pax being able to walk away for any kind of emergency.
Read between the lines.
