The Federal Aviation Administration on Monday said that flights at five airlines had been affected by computer issues.
“Several airlines are experiencing issues with a non-FAA flight planning weight and balance program called Aerodata. Mainline operations and regional operations are affected to varying degrees,” the agency told The Hill. “Airlines included Southwest (SWA), United (UAL), JetBlue (JBU), Alaska (ASA) and Delta (DAL).”
The agency also tweeted about the issue, telling travelers to contact their “airline directly” for information.
It is not immediately clear what caused the outage.
