what ever you do DON'T select any option during the bid process. wait until your get your line then you have 24 hours to send an email to swaps and drops telling them what you want to do.
To max your time off bid lines that touch both sides of your vacation (first trip ends on Saturday and last trip starts on friday) that way you can DTS (drop) those 2 trips plus what ever falls inside your vacation block. now you have about 14 plus days off.
you will NOT get paid for the flying you dropped out side your vacation block, but you can request that you get paid for it our of your sick bank. That way you still get your line guarantee, and now have those days free to now pick up OT at 150%.
hope this helps.
