I'm currently holding 4 seats for 1/2/07 on CO391 connecting with CO667 (MIA-HOU-SEA). I'm waitlisted for mileage upgrades on all of the segments, realizing that the HOU-SEA is the only one where it would be possible. It's now 6 days until the flights and there are still 10 seats availabile in first, and I'm still waitlisted. I guess I have 2 questions:

1) What are the chances they will release reward seats?

2) If they don't release reward seats, and I correct in assuming that my gold status will upgrade us on Saturday (2 of us are gold), or will they somehow default to taking the miles as well?
