It looks like they are still selling discount economy tickets but not award saver for your flight, so there are probably some seats left. Without knowing the route and specific flight/date, it is hard to say. Even so, anything can happen like a cancelled flight before yours or a ton of non-revs. You can't go wrong booking an aisle and a window esp towards the rear of E+. If it were me I would probably select the aisle-window in the last reclinable non-exit row on the right side of the a/c (11 D/F or 14 D/F depending on the configuration).
