10 hours of airport reserve with no pay, they can put you on continued reserve after returning a from a trip instead of releasing you after not having an assignment like they used to do, continued hot reserve. Don't know reserve periods for the month. The only good thing is you can only have three overnight in a row, sucks for commuters, but they can waive this and go to a fourth overnight. 10 days of minimum, and guarantee is only 72 hours.
