When you get within 4.5 hours of guarantee you have to call them and give them the choice of either releasing you from remaining reserve days on the bid or they have to pay you at least 4.5 or whatever you fly, whatever is higher, for the remainder of bid month. They will never release you, so they put the code rmpg on you master schedule indicating that you have called. At that point if they don't use you, not likely, or assigns you a trip that averages 3 hours a day, you will get paid 4.5 a day. Of course if your trip average's more then 4.5 a day you will get the higher of course. You have to call the day prior the next reserve day by 9am, i think, to get it for that next day. Also it must be done for each work block. One call only covers one work block.
