I usually do neither. I'll occasionally pick up over it if there's something easy that falls on the days, but normally I'm happy to get paid to not fly. I've sold it back once. It helps the paycheck but it's sort of a long haul through the months without much of a break.

I think my one main gripe with the AS vacation system is that time can't be banked and used randomly throughout the year to augment a lower credit month. Otherwise it's fine.

As Word has said earlier, it's actually nice to know you can get vacation days. At our old airline you'd get the vacation time credited, but could never use it because the company would never allow anyone but the very most senior the actual days off.
