I am up to 5 weeks and like to actually use my vacations even if they are in the winter. Kids have winter break and other days off I try and match up with vacation. I can always find something to do that I enjoy more than work over a vacay.
Disclaimer. I do typically get my first choice for summer vacation. I also understand that many pilots don’t get even a week in the summer and that needs to change. (Thank goodness for IVD). I just cringe when I see that just because a vacation is in the winter, that the sellback word pops up.
