Hey,
In UA's 787-10 there are 3 rows (20-21-22) of 2-3-2 seating of PP - we are 3 pax flying in this class long haul, and currently assigned the middle 3 seats (D-E-F) in the last row (22).
However I just saw the middle row (21) in front of us is available, so I'm wondering if we should switch to that row. Is there any difference really? is the last row bad? (we like the idea we can fully recline without fearing we are annoying someone that is seating behind us)

And what about the first row (20)? is it narrower than the other 2 rows?

Thanks in advance!
