Regarding e-upgrade priority with two passangers on the same PNR, the wiki states the following supported by one data point from 2021. Have there been other examples to support or refute this? I scanned this thread and didn't see anything but given the number of posts, I could have missed it.

• If two passengers are on the PNR, the priority might be based on the highest status, regardless of who requested the upgrade, per this post
