This has been the single worst travel experience of my life. On Monday December 23rd my flight was scheduled from San Diego to Tampa Bay. It was flight 550 to Denver and 290 to Tampa. Needless to say neither got there. After our plane was delayed 2 hours we were able to board. After boarding we sat on the plane for 2 hours before returning to the gate with plane issues. I was asked to get off the plane. This was at 1:00am in the morning. I had to get my luggage from baggage claim and wait at ticketing for a resolution. There wasn't one. The next available flight was on Thursday the 26th in the evening. But of course now there will be an 8 hour layover in Denver and I won't be arriving in Tampa until the following afternoon. Your staff was under trained and ill prepared for this situation. Now I have lost this Christmas with my kids and family. Absolutely the most horrible experience of my traveling life... This is inexcusable...
