Hi all. trying to wrap my head around some of the verbiage in the Wiki.

"As a non-status passenger (or Ruby member), you can only select the following business class window seats
From second row onward of second cabin on the 767, 787 and 772 (excludes all of the forward cabin window seats and first/exit row of main cabin)
From second row onward of main cabin on the 777W (excludes whole of mini cabin and first/exit row of main cabin)"

I am booked on AA8407 LAX-NRT (operated by JAL) in R class. The flight is operated by a B787-9 and expertflyer shows business class as 7 rows, in a single J cabin, in a 1-2-1 configuration. The AAgent was able to get me seat 3D but did state "all of the windows are blocked"

When I view the flight in expertflyer, I can see my 3D is "occupied." Rows 1, 2, and 3 show the windows "blocked" but the windows in rows 4,5,6,7 do NOT show blocked.
I downloaded the "check my trip" app from Amadeus, and when viewing the JAL PNR (because their own website can't do it), ALL of the windows in rows 1-7 show blocked.

I will hit AA Gold / OW Ruby this month and am trying to figure out if any windows on this bird will become available to me based on Ruby status. The wiki doesn't address the 787 variants thus I'm confused, as its all 1 J cabin.

The other question I have relates to on-line checkin. My first leg is JFK-LAX on AA, so I'll check in with American. Since I can not view the seatmaps for the JL flights on AA.com, I assume I'll just be issued boarding passes for the JAL flights with the seat assignments that the AA res agent got for me. If I can't change these JAL legs seats during OCI, is my only option for a seat change to go to the JAL gate in LAX?

thx!
