Airlines have taken steps to proactively cancel flights during the winter's snowstorms. "It's been a challenging winter," said Todd Lehmacher, spokesman for US Airways-American Airlines. "Our goal is to run as reliable of an operation as possible; it's very expensive not to run a reliable operation." Southwest Airlines also dedicates staff to accommodating customers during bad weather. "If we know there is a hurricane or bad weather conditions, we will issue special accommodations for certain cities," said Michelle Agnew, a spokeswoman for Southwest Airlines.
