I just wanted to report one success with the new system. I just checked in for my flight tomorrow. I had waitlisted an RPU that didn't clear. It appears that it has correctly prioritized my instrument in the UDU waitlist online. How do I know? As a Plat flying out of SFO, I'm never anywhere near the top normally. Nice to know that this feature works.

Sadly F is supposedly full already, so it may not make any difference for me.
