CHICAGO - Southwest Airlines was operating normally Saturday afternoon after a system-wide computer failure caused it to ground 250 flights for nearly three hours late Friday night.
Full service was restored just after 2 a.m. EDT Saturday, but the Dallas-based airline experienced lingering delays in the morning as it worked to clear a backlog of flights and reposition planes and crew.
The airline -- the country's largest domestic carrier -- canceled 43 flights Friday night and another 14 Saturday morning.
Southwest is the latest airline to ground flights because of a large computer outage. But its problem was minor compared to those experienced by two competitors -- thanks in part to its late-day timing.
In April, American Airlines grounded all of its flights nationwide for several hours due to computer problems. The airline ultimately canceled 970 flights. And last year, United Airlines had two major outages: one in August delayed 580 flights; another in November delayed 636 flights.
