I had to call anyway because I found out R is also available on the outbound but it wouldn't show as an upgrade in my res.
They picked up in 1 minute...then put me on hold : )
Thankfully only for a few minutes.
She said "oh, you're right! I wonder why that didn't clear for you?" (as if that's the first time that's ever happened).
Everyone should constantly check waitlisted SWUs. Got NO notification from Expert Flier either, and they do not show R or RN available as of now. Wonder if they just check inventory once a day?
