Southwest Airlines said early Tuesday that it implemented a ground stop due to "intermittent performance issues" from a third-party weather data provider, but flights are beginning to resume.
The company told Fox Business in a statement that the glitch prevented the "transmission of weather information that is required to safely operate our aircraft."
California’s Hollywood Burbank Airport announced on Twitter late Monday that the airline resolved an issue that had suspended departures at its location and flights have resumed.
Social media users from across the U.S. took to Twitter to complain about delays.
Denver International Airport took to Twitter to announce the airline’s computer issues.
"If you’re stuck at the airport, jump on the train for a short ride to another concourse to grab a bite to eat or drink," the airport posted.
Sheryl Gay Stolberg, a journalist for the New York Times, took to Twitter to retweet a post claiming that the issue involved physical copies of weather patterns for flight crews. They apparently could not be printed.
The reporter said she was on a plane from Ft. Myers, Florida, to Baltimore and had been holding at a gate for 45 minutes.
The airline said customers should use Southwest.com to check flight status or, "if flying this evening, consult a Southwest Airlines Customer Service Agent for assistance with travel needs."
