Christmas break is probably the only time that you can guarentee a large chunk of leave, but be careful planning too far in advance....the dates for those leave blocks and the amount of days in them can differ greatly depending on how caught up the squadron/wing is on the training requirements. Last year I think the students in the squadron got seven days max. This year they got 11 days, but since half the students have to be available to fly in each block, the days were split up so that you either got Christmas or New Years, but not both. Something to think about if you are trying to plan to far out. The Stucon and OPs O's don't get know for sure what their leave blocks are going to look like until October at the earliest. Don't get into paying for a bunch of stuff in advanced, because if your plan doesn't fit the squadron plan you may be out some cash.
