Southwest Airline cancelled our connecting flight to Philadelphia without providing a same day alternative. Instead the next available flight was scheduled two days later. They said the closest they could get us to PHL was Baltimore if we wanted next day service but transportation to PHL we were on our own. They did not provide hotel accomodations but would give us a $200 credit on our next flight. To return to PHL we had to fly AA at a cost of over $400 plus cab fare from Midway Airport to Chicago Ohare. The staff was officious and bureaucratic in dealing with the problems they created.
