Don't call the travel department about that as thats not what they do. That is a question for the training department. And they might not even really say. The only time you will really know your schedule is when you bid for sim slots during ground. Then your slot will show you if you have the holiday off or not. If I had to guess the actual days of thanksgiving and Christmas will be off, but only those. Which would make it pretty hard to go home and come back within 24 hours. And its possible that they will still run the training on the holidays becasue they have to keep people moving. When I went through training my differences class was on July 4th even though its a company holiday.
