Cancelled flights pile up at American Airlines affiliate

DALLAS – American Airlines is continuing to cancel hundreds of flights because of computer problems at an affiliate, PSA Airlines.

More than 500 PSA flights were cancelled Tuesday, according to tracking service FlightStats.

American tweeted that PSA has stabilized its computer systems and was trying to resume a normal schedule. The airline did not immediately answer a request for comment Tuesday. It previously said the problem was in PSA’s crew scheduling and tracking system.

PSA is owned by American and operates many American Eagle flights on smaller, so-called regional jets. Many of the cancelled or delayed flights have been in Charlotte, North Carolina, a major American Airlines hub.

The technical issue surfaced last Thursday. American cancelled more than 1,000 PSA flights last week, according to FlightStats and FlightAware.
