Southwest Airlines computer glitch affects Phoenix airport

Stormy weather in Phoenix early Thursday morning caused a computer system outage for Southwest Airlines at Phoenix Sky Harbor International Airport, delaying and canceling flights.

As of 11 am Thursday, FlightAware reported 144 delayed flights and 25 canceled flights at Sky Harbor. Most flights were on Southwest, with 81 delays and 24 cancellations reported.
