Southwest forced to cancel hundreds of flights because it couldn't de-ice planes

Southwest canceled all of its 220 flights from Chicago Midway Sunday due to a shortage of de-icing fluid. While Southwest accounted for the majority of cancellations at Midway Sunday, the airport said over 250 total flights were canceled due to "winter operational issues." Chicago has seen nine consecutive days of snowfall, which matches a record for the city since 1885. Southwest faced similar problems in December when it canceled around 90 flights due to difficulties de-icing its planes. <br/>
