Passing the cabin crew physical requirements is simply not enough. If you want to be a cabin crew, you have to have the traits and character of one. There are a lot of people who are tall, have clear skin, they have the correct weight to height ratio, and are fit, but yet, they do not pass the airline screening process for flight attendants. Hence, it is time to examine ourselves and see how "cabin crewable" are we, on top of the physical requirements.
Below are questions answerable by a yes or no. Just go through these questions and anwer them whole heartedly being as honest as possible to yourself.
You have to be 101% sure that you are ready to become a cabin crew. Do not apply just because it is the "in" thing or because you just want to travel for free or because your friend is one already. Always have with you the right reasons why you want to become a flight attendant.
Try to ask yourself "why do I want to be a cabin crew" and then read these questions silently and answer them by yourself. No need to ask someone to be around you. No one knows what's in your heart but you yourself. After, try asking yourself again why. Have the right reasons too why you want to become a flight attendant, and from here, you will see how "cabin crewable" are you.
