BALTIMORE — BWI is among 40 airports nationwide that will have flights reduced due to staffing shortages caused by the ongoing federal government shutdown.

WATCH: BWI to reduce flights due to shutdown staffing shortage
Transportation Secretary Sean Duffy and FAA Administrator Bryan Bedford confirmed the news during a Tuesday press conference.
According to WJLA-ABC7, roughly 10 percent of all flights out of BWI, Dulles, and Regan Airports will be cut starting Friday.
Duffy said fear of employee fatigue played a big role in their decision.
Most of these workers, like TSA and Air Traffic Controllers, haven't received a paycheck since the shutdown began over a month ago, resulting in no-shows.
Flight cancellations and delays are expected to drastically spike while the reductions are in effect.
"The airlines will notify customers directly regarding specific flight changes," a BWI spokesperson told WMAR-2 News. "The carriers are working to modify their schedules in a way to minimize impact on their passengers."
Still, travelers are advised to check their flight status with their airlines.
"BWI Marshall Airport appreciates traveler patience and understanding during this unprecedented situation," the BWI spokesperson added. "Safety remains the top priority."
Currently, there are about 2,000 air traffic control vacancies nationwide.
