Hi Everyone! I hope I'm posting this question in the right section. I have a flight scheduled in the summer from IAD to LHR and it's my first time on a transatlantic flight in 20yrs. I'm hoping to just buy my seat now but I have a few questions about a few that I have in mind. According to the seat map and the number of seats, it appears I'll be on a British Airways Boeing 777-200 (4-class). Not 100% sure though. I would really like a window seat where the window is actually aligned with the seat. Meaning, I'd rather not be in a seat where it's the middle of two windows (if that makes any sense). From watching a few videos, it seems like the even number seats seem to get the aligned windows. With that information (if accurate) I'm looking at 34k or 36k and possibly even 35k if it comes down to it. I'd like to sit a little farther back, but according to few sites, they claim that 36A/36K are seats that begin to get narrow b/c apparently the fuselage begins to taper in. Is this accurate? and if so, is it really a noticeable difference? As of right now, I also have an option to pick 39A (twin seats right in the back) but I'm uncertain as to whether they can recline if at all. I also fear being too far back may be slightly more bumpy. Even though I'm slightly claustrophobic, sitting in a window seat is fine. However, it does help to be seated towards the middle/back section. I've included a screenshot of the seating chart that I get to pick from. Any advice is greatly appreciated.
