We used a ferry call sign, not the original flight number. They were going to stub it, but then it got more delayed, decided it would be something they didn't want to do, so that's where we ended up with the different call sign and the 19.5 hour trigger on the WDR. It was a very interesting situation.

My thoughts are it is RRPY. The "Pay ADJ" is still on the rotation in MiCrew. I just haven't seen anything reflected on the time card yet (14+ business days now).
