The T-100 etc. windows are the earliest they'll open those UGs, but no guarantees for UGs, ever.
I'm very familiar with how revenue management works, and with this route in particular, which I've been flying more or less weekly for the past two years. AA is just being way more stingy. Nearly as bad as UA now. Continuing devaluation of elite status because they feel they can, whereas AS actually still cares about keeping its frequent flyers happy.
