The Federal Aviation Administration (FAA) is 3,500 air traffic controllers short of the targeted staffing levels, and with many working overtime and without pay due to the government shutdown, there are concerns about performance and by extension, safety.

The US is set to see a 10% cut in flights across 40 major airports, with the government shutdown crossing the 35-day mark and becoming the longest in US history.

The move was announced by US Transportation Secretary Sean Duffy on November 5, with as many as 13,000 air traffic controllers and 50,000 Transport Security Administration (TSA) officials working without pay as per Reuters.

The Federal Aviation Administration (FAA) is also 3,500 air traffic controllers short of the targeted staffing levels, and with many working overtime, there are concerns about performance and by extension, safety.

"We had a gut check of what is our job. Our job to make sure we make the hard decisions to continue to keep the airspace safe," said Duffy, who cited a confidential safety assessment highlighting potential dips in performance of air traffic controllers.

Following up, Bryan Bedford, the FAA Administrator, said, "When we see pressures building in these 40 markets, we just can't ignore it. We can take action today to prevent things from deteriorating so the system is extremely safe today, will be extremely safe tomorrow."

Which airports are affected?

Although the FAA has said that 40 aviation markets across the US will be affected by the flight service cuts, it has not specified airports by name.

That said, Reuters reported that the cuts were expected to hit the 30 busiest airports in the US, including those serving New York City, Atlanta, Los Angeles, Dallas, and the capital, Washington DC.

The cuts are expected to reduce as many as 1,800 flights and 268,000 flight seats, as per aviation analytics firm Cirium.
