As a single traveller in Y who likes a window seat, I much prefer AA's 2-x-2 configuration over BAs 3-x-3. It's a lot better to only have one person next to you than climbing over 2.

IFE doesn't worry me as I take my own, and I find the food pretty comparable. I don't think the booze is worth £8 let alone £82, but then I don't drink alcohol on most flights.
