I saw a question about the difference between "credit" and "pay" which reminded me of a "Duhhhh" moment on my part - not that I had any say in it.
If you have a trip that crosses months, hard pay (block hrs flown) is split between months, but I believe all credit (could be just trip credit) gets tacked on the last day of the trip - ie the new month.
Well if a leg cancels in the first month, the credit will be applied at the end of the trip - in the next month. It makes sense that the company will not know trip credit until the end of the trip.
No worries - unless your credit bump now prevents you from getting that Sweet 2 day WS because you are over the max pick-up.
