Passengers are furious after a computer outage delayed flights on Southwest, United, and Delta (LUV, UAL, DAL)


For the second time in as many weeks, a computer outage on Monday delayed multiple airlines’ flights across the US, leaving passengers furious.

The Federal Aviation Administration and Southwest blamed the delays on a technical issue with the vendor AeroData, which some airlines use to plan weight and balance of flights.

By 8 a.m., the computer issues had been resolved, Delta Air Lines, said, but not before more than 1,400 flights had been delayed and another 136 canceled, according to data from FlightAware.

Some passengers thought it might be a bad April Fools’ joke from the airlines.
