Slightly dated, but I was there over Thanksgiving in 2017. Training was 58 days total with 1-2 days off per week. For Thanksgiving they gave us class on Wednesday morning, then we were released til Saturday, so everyone jumpseated home. There’s another few days off while type orals are going on if you’re lucky enough to go first (or already typed). Even with the 1-2 days off people were going home regularly if they wanted. I think I probably averaged every other week. No idea about Christmas, but best guess is you can depart after class on the 23rd and fly back on the 26th, something like that.
