For example the median expected annual pay for a typical Flight Instructor in the United States is $94,803 so 50% of the people who perform the job of Flight Instructor in the United States are expected to make less than $94,803. Source: HR Reported data as of October 2015.
The median annual wage for flight attendants was $44,860 in May 2015. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less. The lowest 10 percent earned less than $25,930, and the highest 10 percent earned more than $72,090. Flight attendants receive an allowance for meals and accommodations while working away from home.
