Several major US airlines are experiencing significant delays Monday morning after a computer glitch caused flight disruptions nationwide.
Southwest, Delta, United, JetBlue and Alaska Airlines were forced to ground or delay flights due to a problem with a program called AeroData, which is used to calculate the weight and balance of flights before takeoff, according to the Federal Aviation Administration.
More than 852 flights have been delayed and 36 have been cancelled nationwide as of 9.10am Eastern, including one third of flights at airports in New York City, Boston, Chicago, Detroit and Washington, DC, according FlightAware’s MiseryMap.
A significant portion of flights in Dallas, Charlotte, Atlanta and Miami were also delayed.
It’s unclear how many of the delays were caused by the AeroData issue.

Southwest issued a statement just after 7am Eastern confirming that a 40-minute ground stop had been lifted but warning that ‘scattered delays’ were anticipated.
‘We’re working with customers on any impacts to their travel plans and we appreciate their understanding as we place nothing higher than the safe operation of every flight,’ Southwest spokesman Dan Landson said.
American Airlines reported that a few of its regional carriers – which include Envoy Air Inc, Piedmont Airlines Inc, PSA Airlines Inc, Compass, Mesa, Republic and SkyWest- had been affected, though it it unclear which.
‘AeroData is currently experiencing a technical issue that is impacting multiple carriers, including a few of our regional carriers,’ American said in a statement.
‘AeroData is working to resolve the issue as quickly as possible, and we apologize to our customers for the inconvenience.’
United and Delta reported on Twitter that the outage temporarily blocked their ability to print release paperwork.
Passengers expressed their frustration on social media, with a few questioning whether the delays were a misguided April Fools joke.
The FAA has urged travelers to contact airlines directly for updates.
