That's the thread I was reading. Other than something about 35 RJs, I wasn't able to extract many details though. Are those RJs that are within the hard limit but parked because not enough mainline jets are flying to maintain the ratio?

edit: some sleuthing - seems to be related to Compass flow-down rights for mainline pilots and the lack of flow-down ability due to the closure of Compass. http://dalscope.org/2020/10/22/new-s...aft-fleet-cap/
