Sign. Another case of a global upgrade getting stuck and not being reticketed.

Fortunately I watched my trip like a hawk, noticed I was no longer waitlisted (but still in the main cabin), and called.

1st agent: nope you're not cleared / no availability
HUCA
2nd agent: looks like you just cleared (hours ago) but I can't do anything about it
HUCA
3rd agent: you're right. Can I put you on hold while I contact the international reissue desk.

Just glad I did this the day before travel.
