Need help understanding upgrade process on CO
1P, booked on CO flight ORD-SFO, now within 72 hours of departure.
There's been no sign of "upgrade pending" on .bomb, but my understanding was that's how it is for CO metal flights, but since I was able to choose an "extra legroom" row, this is supposed to signify that it recognizes me as elite member/eligible for upgrades (right?).
We've passed the 72-hour mark (my threshold as 1P, right?) and seat map shows 13 of 16 seats open in F, so I expected the upgrade to clear. But there's no sign of it.
If there were only 1-2 seats left, I wouldn't be surprised not to clear now, but with 13/16 available, I thought it would go through. What am I missing or what's probably going on?
