Here’s a different example to help: RES on a 3-day GS all on X days. The last duty period is rerouted, say swapping a penalty lap for a layover at another location. The next day is a LC day (rerouted into the LC day). This duty period is scheduled to release > 4 hours late. L9 is paid for the original last duty period. It is not paid for the new last duty period AND it is not paid for the trip credit (TRP, MCD, ADG), as the final duty period DOES NOT INFRINGE on an X day.
That is very (not) helpful example. By that I mean thank you for posting it, I understand it better now, but it's not what I wanted to hear.
I know you already know this, but this is an unfortunate aspect in many ways on RES. A RES GS/QS/IA on only x-days rerouted into a LC day loses out on not only L9 pay, but all the trip credit that would have been above guarantee.
This raises another question though, and that's the timeliness of PB/PR application. The situation you describe (RR into LC day) SHOULD only be possible on a carry-out trip with LC days at the very start of the next bid period. If it happened in the middle of a bid period, I think the RR should immediately trigger PB/PR and the LC day isn't there anymore.
