Seriously disappointed in SWA. Flight from MCI stopping in Denver (to pick up 9 yo grandson) then on to San Diego for a cruise was canceled due to ice storm. Swa had no other flight options that would stop in Denver and get us to cruise in time. So we drove to Denver though the ice storm and flew first swa flight out the next morning with our grandson. Swa did not charge us the difference for our flight out of Denver but did charge us the difference ($600) for our grandson’s flight and our return flight to Denver. They said those changes were our choice, not because of cancellations. It is not a choice to send a 9 yo to San Diego over night by himself and it is not a choice to return to Kansas City when your car is in Denver! Swa had an opportunity to save the day but chose instead to give us reason to never fly swa again.
