How much do flight attendants make? It depends on the carrier, company seniority, and number of hours worked each month. On average flight attendants make $35,000-$40,000 a year. What most people donât realize is newly hired flight attendants in the U.S. start out only making between $14,000 â $18,000 a year.
While the replies to this question offer a lot of good information, it's pretty much all in terms of dollars-per-hour, and that's misleading. In my experience, generally speaking, a new-hire Flight Attendant earns a very low salary, barely above the poverty line. (I started in 1991, and earned $18,000 my first year.) A senior Flight Attendant (15+ years) earns an average of around $60,000 per year.
