Just another data point on this. Flying JFK-SFO tomorrow.
Watching these flights like a hawk since my upgrade from 3 MONTHS AGO was waitlisted. At 24hours exactly, all flights turn J space into R space. But R is not being cleared for those on the waitlist.
This is more evidence that RPU's on this route are not being cleared correctly.

UAINSIDER, are you listening?

There is no way that the 11am, 2:30pm, 5:35pm, and 7pm flights on THURSDAY evening (read: consultants, full-fare, Y/B/M) have no waitlisted passengers at the 24hour mark for p.s flights. Clearly RPUs are not being processed by the computer correctly.
I am also interested to learn if others are noticing that this at the 24 hour mark on this route, J turns to R automatically (and incorrectly)...
