We were eating lunch at a restaurant on our way to the airport. This was on a Thursday and we were flying to Fort Lauderdale to catch a cruise on Saturday. I received an email from Southwest saying they had cancelled our flight. We were suppose to fly to Baltimore (just a stop, didn't have to change planes) and then on. Well, the leg from Baltimore to Fort Lauderdale was cancelled. Sorry for the inconvenience. I got online (thankfully we had our iPad with us) as well as called them. There was no way to get us down there on Thursday and only 1 seat was left for their flights Friday. That was it. She offered no more. I asked if they could book us on another airline. No. I asked if they flew out of Chicago. Good news! They have a direct flight on Friday. Oops, that one only has 1 seat. Hey, found another! But, it will cost $360 PER TICKET more to get that flight. I was dumbfounded. Charge us double what we paid because they cancelled our flights?! I had asked why it was cancelled and she said she didn't really know but it looks like there were a lot of delays by air traffic control. Uh, what? So our option was to lose a day of vacation, drive to Chicago, lose the $ on the hotel we had reserved in Fort Lauderdale for that night AND pay $720 for the privilege to fly Southwest out of Chicago. Not my finest moment but I told her coolly/calmly that we would drive to Fort Lauderdale before we paid them more money (which would have been about a 24 hour drive). Thankfully we were able to fly Allegaint Air that evening to Orlando and rented a car and drove to Fort Lauderdale. We were still ahead money-wise than Southwest's solution. I'm hoping to get Southwest to reimburse us for the rental car but I'm not hopeful.
