This worked for me even on mileage upgrades since the change, and on a RUC three weeks ago.
This morning, though, I'm dealing with uninformed agents searching for the original U class and trying to put me back in Y. So now I get to play the HUCA game. Currently trying DeltaAssist.
I don't think you understood what I was saying. If you're on the noon flight and want the 8:00 AM flight, and hope to get there via the 4:00 PM flight, the 4:00 PM flight needs to have RP/OP inventory for you to confirm the upgrade. Sure, once you have it, you can switch to the 8:00 AM flight with F1, but the chances of the 4:00 PM flight having instrument upgrade availability on day of departure is quite small.
Good luck with DeltaAssist. They haven't been on top of their game this weekend.
