You can also give your trips away to other pilots (that doesn't need enough reserve coverage) or use an "authorized personal drop (APD)" which you get one a year. You can use the APD to drop a trip, or up to I think 4 reserve days. Also, there is a way to move vacation from somewhere else in the coming year, to drop a trip in the present month. It pays like vacation (which isn't a lot, 3:30-3:45 per vacations day vs 5:15 or so for a day of flying).
