So I just booked an AA award flight on a 777-200 (ORD-LHR) for late August 2021. I had forgotten all about the "rocky/shaky" seat issue on some 777s. Is that still a thing, or has AA made good use of the slow COVID times to fix the issue? (well, I can dream, can't I?)

If this is still an issue on some planes, is there any way to divine which one you get, or is it a complete crapshoot?

Spouse has serious motion sickness issues (she really can not stand sitting facing backwards in anything that moves, she gets sick), and me, I'm a light sleeper so looking to avoid the nighttime shakes. We are in business class and most seats show unassigned at this point. I grabbed 1L and 2L when I booked, figuring I cold swap for a better seat if needed (we prefer window seats rather than the center "honeymoon" pair), but seats that don't make her hurl or wake me up are top priority.

Thanks for insights.
