Last month I flew on the 777 from TLV-LAX in C class in seat 10A. The legroom was fantastic. However, like Latus said, it's not a lie flat seat, and being 6'2" I had trouble getting comfortable in the full recline due to the foot rest. With it extended it wasn't long enough, and with it stowed, there was too much of an incline/bump.

Otherwise I was happy with the service.

It looked like the seat next to 12K (maybe 12G) is the seat for the reserve pilot.
