Most people have the impression that being a cabin crew is just a high class waiter and nothing more. So I am not surprise that I get the above question the most when they intend to apply as one. There are actually career progressions when you join as a junior crew whether you chose to fly or prefer a management position on ground.
Let’s start with the bottom position all the way to the top if you chose to be a cabin crew as a lifelong career. Different airlines have different rank for example in MAS/SQ, there are four ranking from a normal Flight stewardess to leading stewardess, chief stewardess and finally In flight supervisor.
