Practicality, personality and perseverance are key attributes for those wishing to join an airline as a flight attendant
There was a time that the life of airline cabin crew was viewed with deep envy, with a (rather erroneous) public image of flight attendants jetting around the world having an incredible time. Little was mentioned about the job itself.
Today, air travel is far more common and most who travel will quickly realise the primary role of cabin crew is to ensure the safety of passengers. Everything else is secondary.
