Automotive technicians earn an average of $56,700 a year and work on nearly 30 million planes each year.
But the salaries can get more complicated when you factor in the costs of owning, maintaining, servicing and refueling an aircraft, according to the Aviation Maintenance and Regeneration Association.
This is because the majority of aircraft maintenance and repair workers earn less than the federal minimum wage of $7.25 per hour, according the trade group.
The union wants more employers to pay at least $10.50 per hour.
It’s asking for a minimum of $15.60 per hour for aircraft mechanics, $20.40 for mechanical engineers, $24.20 for flight attendants, $28.20 per hour and $33.20 an hour for pilots.
It’s also asking for an increase to the hourly minimum wage for maintenance and repairs from $9 to $10 per hour in 2018.
That would allow employers to cover costs such as fuel and maintenance, which are more expensive for airlines.
While a lot of employers are doing their part to address the growing wage gap, not all employers are on board.
According to the AMA, the median hourly wage for an air traffic controller is $23.77 in 2016, while the median wage for a maintenance and maintenance technician is $29.88.
In addition, there are more than 1 million people working in air traffic control in the United States and more than 400,000 workers on the job at the moment.
A major concern is that this group of workers may be underpaid and under-utilized.
