Yes, an introvert can absolutely be a flight attendant (air hostess). While the job involves constant face-to-face interaction, many introverts find they can "switch on" their professional persona for service and safety tasks. In fact, many introverts enjoy the lifestyle because of the significant amount of alone time provided by hotel layovers; the industry even has a term, "slam-clicker," for crew members who go straight to their rooms to recharge. Introverts often excel in this role due to their strong listening skills and calm demeanor, which are vital for managing passenger needs and in-flight emergencies.
