Fewer than 10 flights at Charlotte Douglas International Airport were canceled early Sunday after a computer glitch threatened thousands of American Airlines flights this month, FlightAware.com reported.
On Saturday, the union for American Airlines pilots told ABC News that at least 12,000 flights were without pilots Sunday through the rest of July after a glitch in the company’s scheduling system let thousands of pilots drop their scheduled flights.
The airline, in a statement, said it restored most of the affected flights.
“Our pilot trip trading system experienced a technical issue,” according to the statement. “As a result of this technical glitch, certain trip trading transactions were able to be processed when it shouldn’t have been permitted.
“We already have restored the vast majority of the affected trips and do not anticipate any operational impact because of this issue,” according to the statement.
It’s unclear how many Charlotte trips may have been impacted by the glitch.
By 2:30 p.m. Sunday, seven Charlotte flights were canceled, FlightAware reported. Three of the flights were on American Airlines, according to the flight tracking site.
More than 100 flights were delayed at the airport, FlightAware reported.
Delays include 66 flights originating at the airport, or 11% of scheduled departures, and 75 flights headed to Charlotte. More than half of the delayed flights were on American Airlines.
The July Fourth holiday weekend is one of the airport’s busiest, and officials advised travelers to expect crowds and long lines.
Passengers can check Charlotte’s real-time parking availability through the airport’s online parking map.
