Hi all! I've been stalking my LAX>HKG flight next month (10/16 AA193). There's still plenty of business seats available (J7), while there's only 1 seat left in first, although EF is showing F0. I have been looking at recent AA193 flights and it appears C space is opening up around 12-14 hours before the flight. How are my chances looking at a miles+copay upgrade for this flight now that first class has booked up?
