I’m not a Flight Attendant but I am a flight crew member. What I would do, or advise you to do, is have a cover letter that explains why you think you would be a great flight attendant. Make sure you list that you speak three languages. Make sure you let them know you have sales experience.
The number of hours you work in a day can vary from carrier to carrier and also from trip to trip. Most of the time you will be working three or four day trips. I look at it as if I’m away from home I may as well be working. If you are working for a “legacy” carrier and plan on doing international trips you will work fewer days but longer days as well. A flight from Newark to China is about 14 hours long. If you work for a LCC, low cost carrier, you will be mainly domestic and probably no more than 10 hours a day with breaks between trips.
Keep in mind that the pay that flight attendants make is not the greatest. Most of them do the job for the perks like free travel. If you have illusions of it being a romantic job, it’s not. Especially since September 11th. Be ready to pass a 15 year FBI background check. If you can’t, you won’t get hired.
Some of my FA friends love their jobs and some hate it. It is all seniority based meaning as a new hire you will be working all the trips no one wants. As you get more senior, you can pick the flights you want to work. That goes for days on and off as well. You probably won’t have a major holiday off for a few years. Airlines are 24/7/365. You will miss birthdays, weddings, anniversaries, and so on. But you will also meet some of the most interesting people in your life.
Some of my FA’s have been lawyers, doctors, nurses, and so on. Your main job is safety, not service. Service comes second. So if you know CPR, let them know. If you have taken advanced first aid, let them know.
Airline travel and crews have changed a lot over the last several years. With that said, it can be a very rewarding career.
Good luck.
