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 airline pilots, copilots, and flight engineers was $114,200 in May 2012. The median wage is the wage at which half the workers in an occupation earned more than that amount and half earned less.he average captain at a regional airline earns about $55,000 per year, while the average captain at a major airline earns about $135,000 per year. In addition, airline pilots receive an expense allowance, or âper diem,â for every hour they are away from home, and they may earn extra pay for international flights.
