It is definitely a possibility. Basic Indoc is the first two weeks of New Hire Training (with the weekend off between those two weeks). That would complete before Christmas. You would then have time off (with pay) waiting for your aircraft specific training. This can be a few days to a couple of weeks. Even if it was just a couple of days, the Training Center is closed on Christmas, so you will not be scheduled on Christmas day. I could see them having new hire classes on the 1st and/or the 8th this year based on how the Calendar plays out with Christmas being on a Friday.

Of, course that all depends on how much training they are trying to get done over the winter. Winter is normally a pretty busy time for training in general and winter is usually a very busy time for New Hire training. However, the saying around aviation is that the Long Range Planning committee meets twice a day, so unfortunately any plan they have for next December is written in very light pencil at this point!
