Not exactly. For the first trip (Reg, XXX, XXX, XXX, LC), you get the Pay no credit for the 3 x days (Think Reserve GS) for those days as well. The last day is Pay and Credit towards your guarantee, and the kicker is that all extra credit goes towards your guarantee on that last day as well. So say your trip has a red eye on day 2 and no FDP on day 3, all the credit earned for day 3 of that trip would be paid on day 5. Thus you would get no GS pay for day 3 and all of that pay and credit just goes towards guarantee. (You still get a PB day though)

Reserve GS/SS with LC at the end of the trip are not the best idea, unless the trip is driven by block hours only, and the block on the x day portions of the trip are over 5:15 per day average.

Clear as mud?
