I am EXP. My companion is Gold. Requested Upgrade on 3/31/22 for Flight to LAS from DFW on #1996

Requested the upgrade well before the 100 hour window and i believe there were 8+ seats. And now I only see 3. Is it fair to assume that there are several folks 'ahead' of me with either CK or EXP (with higher spend) and/or people are spending cash for FC?
