A flight attendant's job requires so much flexibility with the constantly changing schedules and flight times, that this is a major concern of airline managers. If you cannot display a positive attitude in the face of adversity, this is probably not the job for you. Courtesy and friendliness also weigh heavily on a recruiter's decision. Dependability is a big issue with recruiters as well. They won't wait for you in a job open house.
Doors close promptly at the designated time.
It takes a lot of maturity and stamina to do this job. Enthusiasm and energy. Energy is contagious and interviewers love it. Airlines like their image to be projected in a dignified, intelligent fashion. Anyone who is sloppy or awkward will not be considered.
