Southwest still struggling with flight delays, cancellations

Southwest Airlines is seeing higher numbers of canceled and delayed flights for a third day as it tries to recover from technology glitches earlier this week

DALLAS — Passengers on Southwest Airlines had to deal with canceled flights and delays for a third day on Wednesday, as the airline tried to recover from technology problems that started earlier this week.

By late afternoon Central time, Southwest had canceled nearly 400 flights and more than 1,000 were delayed, according to tracking service FlightAware. Combined, the disruptions affected 40% of the airline’s schedule.

A Southwest spokesman said the airline fixed what it termed a network-connectivity issue that cropped up Tuesday but was still experiencing cancelations and delays as it worked to resume normal operations.

While Southwest’s problems on Wednesday were far more extensive than at other U.S. airlines — American canceled about 40 flights and delayed 350 more, according to FlightAware — it was an improvement over the previous two days.

A problem with weather data supplied by a contractor caused Southwest to delay about 1,500 flights Monday. On Tuesday, the Federal Aviation Administration briefly grounded Southwest flights and the airline canceled about 560 flights and delayed 1,800 more over the network issue.
