Well, there's one seat left in F right now - it's a paid seat for MEM-LAS, not an R-class seat. I'm hoping an online check-in right at 5:10 will secure that upgrade.

As for the return on Sunday - I just got off the phone with an elite agent - my LAS-IND flight has another R seat left as well (but I got passed over on the upgrade for that too when the EUA ran last night) - seems like I had more success as a Silver! I guess Vegas is a tough market, but if the seats are there, I really think they should upgrade people - at the very least fill it up with another Gold or Plat if not me - but don't let it go empty til check-in!
