good evening,

I'm flying LHR-PEK next month, so am choosing seats now. My issue is, i've never done such long haul in WT before, and I don't actually know which seats would be best. From the website, it looks like this one, 29j or b, is a window, with only one person to climb over, and more leg room. Is that a misrepresentation?

or would i be better off going for a window on one of the twin seats down the back of the plane? Whatever i get, the window is a necessity, the legroom ideal. I think i like the look of 29j since it appears to have a bigger space in front of it.

thanks
