Upgrade cleared at the 44 hour mark . . . interestingly, I had just checked and the flight showed J9 R/Z 7 . . . and then as I was looking, I got the e-mail saying it cleared--looked back at seatcounter and it now shows J6 Z/R4, so it looks like they cleared 3 seats at the 44 hour mark.

Anyhow--thank you all for your replies--it was interesting to see this process work for a change! Happy Thanksgiving!
