A major computer outage is affecting flights all over the United States this morning causing delays across the nation, especially the West Coast.
What caused the outage was an IT issue from an outside contractor. Airlines go to this outside contractor to receive a wing and balance okay confirming that everything from the cargo to the passengers are properly balanced before take off.
When this system went down, most affected was Southwest Airlines, however regional carriers that work for United, Delta, and American Airlines were also affected.
The outage lasted for approximately 40 minutes, but the effects will continue to ripple throughout the day, because so many flights were delayed, clogging up the system.
