Quick comparison NCW vs OCW
Just had the joys of a LHR-JFK-MAN over the last few days.
LHR-JFK 747 with NCW seated in 62K - great comfy seat with loads of space. Storage cabinets under window were great as was the addition of the laptop storage tray. Must admit I didn't miss the drinks tray until I read it on here and found the AVOD great (it worked and allowed me and Mrs K3LVC to sychronise what we were watching). Only real downside I found was seat movement as the trolley went past - there must be a slight lip in the floor which made everything shake/move.
JFK-MAN 767 with OCW seated in 2A - considerably less space/comfort but I did get a drinks tray (!) - zero storage space (underseat useless with seatbelt on) and IFE failed to work (still waiting for promised BA response to this).
Understand it was different planes and therefore enviroments but the 747 with NCW won hands down.
