Southwest Airlines says computers running again at PHL after outage

PHILADELPHIA (WPVI) -- Southwest Airlines says all of its computers at Philadelphia International Airport are up and running again following technical issues that affected hundreds of flights over the weekend.

Technical problems led to long lines and handwritten boarding passes for Southwest passengers on Sunday.

The technology glitch starting at 10 a.m. Sunday meant frustrated passengers and missed Southwest flights nationwide. Officials say 450 flights were delayed Sunday.

"We were trying to check the flight status all day, and just could not get on the computer at all," said Terri Hall of Chicago.

The Halls arrived two hours early for their flight to Chicago.

"We were worried about coming here to see if we would be able to get in and everything," said Hall. "I was surprised to see nobody here."

Southwest officials have not said what caused the problem, but say there's no indication that the problems are a result of hacking.

Computers, reservation centers and the mobile app were affected.
