IT outage causes hundreds of US flights to be delayed

Hundreds of flights were delayed and tens cancelled as Southwest, Delta, United, JetBlue and Alaska Airlines were impacted by the outage.

The issue stems from a computer program called AeroData, which is used to calculate the weight and balance of flights before takeoff to determine flight plans and make fuel calculations, according to the Federal Aviation Administration.

Delta Airlines told passengers on social media: “We are currently experiencing a system-wide outage. We are working diligently to get it back up and running”.
