Computer issues have resulted in the cancellation of around 2500 flights for an American regional airline.
PSA Airlines, which operates under the American Eagle brand for American Airlines, saw a computer glitch kick in Thursday, which disrupted its crew scheduling, CNBC reported.
As a result all of its flights were cancelled Tuesday morning as the airline worked through schedules to get aircraft crews where they needed to be to resume operations, American Airlines spokeswoman Katie Cody said.
However the airline has since "stabilised" its computer system, which was operating too slowly to schedule crew members in time for flights, Ms Cody said.
PSA will now operate a reduced scheduled over the next few days as it works to restore its full services.
The American Airline subsidiary operates about 12 percent of American Airlines' 6700 daily flights.
