PSA Airlines, a regional carrier for American, had already canceled 275 of its scheduled flights on Thursday and 400 more on Friday.
Employees at TLH say they believe this is an "after-effect" of the glitch that caused hundreds of delays late last week.
"Charlotte Douglas International Airport continues to provide assistance to the airlines and our passengers as PSA and American Airlines work to resolve their operational issues. This issue is not affecting any of our other regional carriers or mainline flights", the carrier added.

Inbound flights have been delayed to Charlotte Douglas International Airport after being held at their origin until Sunday, according to FlightAware. To better control the flow of PSA aircraft to Charlotte, a ground stop has been issued until 3 p.m. ET.
"We understand that these cancellations have been frustrating for our customers, and we are doing everything in our power to get things back to normal as quickly as possible", American Airlines said in a statement.
