Start checking 100 hours out when upgrades clear and hopefully something better will open up that's not a premium seat. There are premium seats open as far back as row 23 but not a single non-premium seat open right now. Other than that, you'll need to select a seat at check-in or at the gate. No assurance you won't get a middle seat if that's all that's left at that time.
