Yes I have 2A on the way back, but on the outbound it's already taken. I currently have 2K, but 1K is also available. I flew in 1K when I first flew the new F and I don't remember any issues, but I do generally prefer the second row. Only benefit of 1K here is that there is no one right next to me since the entrance to 1E is on the A side.
So if it were up to you, 2K or 1K?
The well known (at least on FT) phrase ‘first world problem’ wells up in my head here.
(Not that I wouldn’t be fretting about the same issue myself

)
2K
