Why restrict it to 30 ?
Are we past it over that age ?
Many wannabes on this site are over 30 and have much to offer. They are also more certain of what they want out of a career than many 18 year olds too.
Is ageism replacing sexism and racism now ?
Ok I am over 30 so do have a bias on it but I am far from past my useful working life at 33 and have many years to offer the right airline.
