any ideas?
I assume nothing can be done now that it’s less than T-24 so I’m not going to bother even trying to ask. The return is still waitlisted.
I had the same experience, as well as another poster IIRC. I speculate that if the upgrade doesn't clear 24-30 hours before departure, ANA cancels the upgrade request.
