LOS ANGELES -- Last week's winter weather travel mess is lingering like a vicious hangover into this week - and the headaches have been migraine-proportioned for Southwest Airlines, its CEO Bob Jordan, airline employees and most of all its frustrated passengers on Monday.At Hollywood Burbank Airport, virtually every Southwest flight listed had been canceled."We will do everything that we need to do to right the challenges that we've had right now," he said, including "hotels, ride assistance, vans ... rental cars to try and make sure these folks get home as quickly as possible."Emphasis on safety Southwest earlier responded in an emailed statement Monday afternoon emphasizing safety: "With consecutive days of extreme winter weather across our network behind us, continuing challenges are impacting our Customers and Employees in a significant way that is unacceptable," the statement read.Calls made Monday afternoon by CNN to Southwest's customer service did not go through, so customers couldn't even get in the queue to speak to a representative."
