Closing some US airports due to TSA staffing would have big consequences, experts say

How likely is it that the funding lapse will lead to airport closures?

With few confirmed details, it’s hard to say. But officials have suggested that the possibility of closing airports will become more likely the longer TSA workers go without pay.

Aviation security expert Sheldon Jacobson, whose research contributed to the design of TSA PreCheck, said that Trump administration officials appear to be floating the possibility of closed airports in an effort to pressure Congress to reach an agreement on funding DHS.

“This is a situation that, once again, the politicians are trying to move the needle to get people to compromise by making threats. Are these threats realistic? Yes. Are they a good idea? No,” Jacobson said.

Jacobson and other aviation experts said the messaging also suggests that sending federal immigration officers to help out at airports with security staffing problems hasn’t been a successful solution.

The White House has said ICE officers helped reduce lines by monitoring crowds and checking IDs. TSA union leaders and other critics have called the move ineffective, arguing that immigration officers don’t have the required expertise and experience.

Which airports are the most at risk for closures?

Larger airports with hundreds of officers can close some of their checkpoints and even their TSA PreCheck lanes and continue operating. The smallest of the 440 U.S. airports with security screeners don’t have that option.

Smaller airports that only have a single checkpoint might have to shut down temporarily if they can’t get enough officers to operate them. That could happen if a number of their officers don’t report for any given shift.

Small airports have “a smaller pool of people that you can draw from to keep the airport open,” explained Eric Chaffee, a Case Western Reserve law professor who studies risk management, including in the aviation industry. Larger airports, by contrast, are often “much better able to absorb a handful of people calling out.”

The closing of these airports would likely be “uneven,” Chaffee said — potentially affecting facilities ranging from airports with just a few gates to small regional hubs. But, he warned, that any temporary closure of small airports could cascade through the broader air traffic network because it is a “highly interconnected web.”

What would be the impact of small airport closures?

Experts stressed there would be consequences for the aviation system as a whole.

“Every airport, no matter its size, has some impact to the National Airspace System,” said airport security expert Jeff Price.

Jacobson, who is a professor at the University of Illinois, said airlines rely on passengers from small airports to fill out their flights at major hubs.

Others point to ripple effects for the communities smaller airports serve.

“Despite the fact that we’re talking about small regional airports, this is a big deal,” Chaffee said, pointing to disruptions for both businesses and travelers. “Ultimately, if this does occur, having to drive a half hour to an airport is a lot different than having to drive three hours to an airport.”

If flights stop operating at some smaller airports, it could hit nearby communities and their economies hard, especially businesses operating in hospitality and tourism. It could also jeopardize airport workers’ jobs, such as janitors and employees of restaurants and shops that serve travelers.

Meanwhile, financial strains would continue to pile up for TSA officers going without pay.

With there being a slew of potential economic repercussions from air travel disruptions, Jacobson said “We are playing with fire right now when we are threatening such a large contributor to our GDP.”
