A technical glitch caused flight delays across multiple U.S. airlines Monday morning.
A program called Aerodata, which that monitors the weight and balance of planes, went down for a short time. The system was up and running by about 7:30 a.m., but airlines — including Southwest, United Airlines, JetBlue, Alaska and Delta — were all experiencing residual delays, according to the Federal Aviation Administration.
Both Delta and Southwest responded to customers on Twitter who were expressing their dismay with the travel disruption.
"It's affecting our flights system wide, and we're working to see if it's affecting any other carriers this morning as well. In the meantime, once more information has been made available our Agents at the airport will be happy to disseminate it to y'all," said a Southwest tweet.
Nearly 500 Southwest flights were delayed by 7:45 a.m. Monday, according to flight tracking website FlightAware.
A Southwest statement said that the airline had lifted a ground stop of 7:05 a.m. that had lasted for about 40 minutes " during an outage with a vendor that services multiple carriers with data used in flight planning."
