Which airline suffered an operational meltdown this week that resulted in thousands of flights being canceled?

• Southwest Airlines:A winter storm across much of America led to widespread flight cancellations over the Christmas holiday. By Monday, air travel was more or less back to normal – unless you booked your holiday travel with Southwest Airlines. While the storm caused the initial flight disruptions, it was Southwest's internal software systems that turned a normal problem into a disaster. The disruption was the largest and most costly in the history of U.S. airlines. In all, Southwest canceled roughly 15,750 flights since winter weather began disrupting air travel on December 22.
