Had the same hope -- am flying tomorrow domestically and it's showing C7/J7/D7/I7 in EF and the seat map shows 8 unassigned seats in F. I just checked in and grabbed MCE seats for the family, so I'm skeptical there are any elites on this flight, or any left that haven't already been upgraded. This seems like a missed monetization opportunity for AA. I'd be willing to pay a reasonable amount.
