Southwest Airlines runs out of de-icer, cancels all flights from Midway

"Tiller declined to be specific about what measures were being taken to accommodate passengers, but she said that while Southwest doesn’t typically offer 'gestures of goodwill' as a result of weather-related events, the large number of cancellations in this case has the airline making “additional considerations for impacted customers.”

"But aviation consultant Michael Boyd noted that Southwest’s de-icing debacle was likely a one-off event that could only be blamed on Mother Nature."

So SWA typically might not take responsiblility for 'gestures of goodwill' to accomodate its customers because the company's inability to ensure an adequate supply of a consumable required for operations, and the mechanical failure of a pump, is being palmed off as weather-related? Not what I would have expected from them.
