08:28 AM EDT, 10/08/2025 (MT Newswires) -- Air traffic control staffing shortages caused by the US government shutdown continue to contribute to flight delays at US airports, according to media reports and tracking data.

More than 500 flights were delayed early Wednesday and 25 canceled, according to the aviation traffic tracking website FlightAware.

Reuters identified airports in Houston, Nashville, Dallas, Chicago and Newark as being among the most affected.

Chicago's O'Hare International Airport reported 705 flights delayed Tuesday, the tracking website said.

The US Federal Aviation Administration has reduced the number of flights per hour at the airport, Reuters reported.

The FAA did not immediately reply to MT Newswires' requests for comment.
