if not all, most airlines have their first the initial screening for f.a. aspirants. this is a physical screening which is very important since a stewardess is a front line job. the height, if im not is mistaken would be at least 5'3'' without heels. you should have a good set of teeth, flawless skin (not even a pimple mark) and strictly no visible scars. some airlines, like oman air, would employ ladies only if they are 21 years old to comply with some legal rules. my friends and i applied in a local airline. we're 4 but only one of us got in. i didnt get in because of my scoliosis, 1 of them did not get in because of her sungki. and the other didnt pass the interview. btw, you should also have to have that friendly vibe with good english speaking skill. have all these with confidence im sure you'll get in.
