I can't look up the contract right now, but I think vacations needing to be rebid or not has to do with how much time a base is open. A base opened in the last 12 months does not require you to rebid, otherwise you would need to. I don't think it has anything to do with type of training. Again, I'm not 100% on that but I would look it up before sitting pat on it with a seat/airframe/base change.
