Morning! Have sat on 1K (slightly annoying near crew cupboard) and 2K which was fantastic - both on night flights LHR-SIN and back. However on LAX day flight in August have choice of all seats; travelling with friend and want middle two. 2EF or 3EF ?? I don't remember the staircase impeding too badly into row 2, but then again I wasn't sat there. Any first hand experience?
