The national security of the United States relies on a healthy airline industry. That requires modern reliable airplanes — and highly skilled pilots to operate them.

However, the United States has a shortage of pilots right now, particularly at the regional airline levels.

According to the Federal Aviation Administration, there were about 827,000 pilots in America in 1987. Over the past three decades, that number has decreased by 30%.

Meanwhile, during this period, there has been a tremendous increase in the demand for air travel. The International Air Transport Association predicts that, over the next 20 years, air travel will double.

This is a classic case of low supply and high demand. This mismatch has created a perfect storm that could wreak havoc on the US airline industry over the next decade. The somber news is this shortage is going to get much worse.

I have not only studied and researched the airline industry since 1978, but I also was a pilot for 19 years, before going back to academia in 2006.

Industry changes

In the 1970s, when most of today’s airline pilots like myself were growing up, piloting for an airline was considered a prestigious career.

The job offered not only high salaries and nice schedules with many days off, but also a respected position in society. In the early 1990s, pilot salaries approached $300,000 in today’s dollars for some international pilots.

What’s more, during this time, the military had a steady and consistent demand for pilots. A young aspiring aviator could go into the military to receive all of his or her flight training. Once these pilots had fulfilled their military commitment, they were almost guaranteed a good job flying for a major airline.

Today, this is no longer the case. The career of the airline pilot has lost its luster.

This is due in part to deregulation. The 1978 Airline Deregulation Act kicked off the era of the low-cost carrier. As a result, airlines such as Pan-Am went out of business.

Then, the 9/11 attacks left the airlines in poor financial condition.

Five of the six major legacy airlines in the United States declared bankruptcy: US Airways, Delta, Northwest, United and American Airlines. I clearly recall a day a couple weeks after 9/11, when one of my flights, from Washington DC to Orlando, Florida, boarded just one passenger.

From my own experience, I can attest to many pilots like myself who were forced to vacate their captain position and go back to first officer, resulting in their pay dropping from roughly $190,000 per year to $75,000 per year.

Fewer new pilots

Meanwhile, the number of pilots supplied by the military has dwindled. Much of this is due to the use of unmanned aerial vehicles.

In the 80s, roughly two thirds of airline pilots were ex-military. Recently, that percentage has dropped to less than one-third. The Navy predicts a 10% pilot shortage in 2020, while the Air Force predicts its own 1,000-pilot shortage by 2022.

This means many young aspiring aviators now have to pay for their own flight training.

That can be very costly, easily exceeding $100,000, especially in light of an uncertain future. Many are simply unwilling to take the risk. This effect was aggravated by the great recession.

In 2009, Congress changed the mandatory retirement age for airline pilots from 60 to 65. In my view, this didn’t solve the problem, but merely kicked the can down the road.

A 2016 report by Boeing shows that 42% of the pilots currently flying for the major airlines in the United States will reach their mandatory retirement age of 65 in the next 10 years.

Meanwhile, this move crippled the career advancements of the more junior, younger pilots. That’s caused many of them — including myself — to seek a more stable career.

If that’s not enough, there have been significant changes in the work and rest rules for airline pilots.

After the Colgan crash near Buffalo in 2009, Congress changed the pilot experience requirements for the airlines. Newly hired pilots must now have a certificate which requires a minimum of 1,500 hours of flight time. Prior to this law being passed, pilots could fly for an airline with a minimum of 250 flight hours.

Growing demand

The other side of the shortage problem is that demand for well-trained pilots is actually increasing. The greatest demand is in Asia and the Pacific regions.

Manufacturers such as Boeing and Airbus are delivering more and more airplanes and plan to continue to do so over the next 20 years.

Congress also changed the duty time rules in 2010 to mitigate pilot fatigue issues. This change meant airlines had to increase their pilot staffing by 5 to 8% in order to cover the same schedule. In other words, they need to hire even more qualified pilots.

The US major airlines are not yet directly experiencing the pilot shortage. But smaller regional airlines are experiencing this firsthand. Their schedules have been reduced and some, such as Republic, have been forced into bankruptcy as a result of inadequate staffing.

The industry has taken a few steps to address this problem. Regional airlines now offer much higher pay and even signing bonuses.

Also, there have been some minor amendments to the 1,500-hour rule. Pilots can now receive their certificate in fewer than 1,500 hours if training takes place at certain flight schools. There’s even talk of extending the retirement age again to 67.

In my view, these steps alone will not solve this problem. Airlines need to consider forming their own pipeline.

The airlines will need to begin recruiting and training their own pilot candidates. For example, in April, American Airlines, where I used to work, announced the American Airlines Cadet Academy, with the intent of recruiting the next generation of pilots.
