Having gone through training twice at this company (once recently), the training department does a pretty bad job of scheduling far in advance. Not making excuses for them because I think they can do a better job especially with known duration events such as indoc and systems class, but they have a constantly changing puzzle they have to piece together especially with sim time. Some guys need more time and there is only a finite blocks of sim time open. You will definitely get the holidays off and you might even get lucky to have off after indoc through the holidays.
