Don't the LGW 4-class 777s have the old WTP and WT cabins? The table in the wiki would imply that G-VIIV-W-X-Y have 2010 cabins and Thales, but the BA source says 2000 and Rockwell Colins. I don't know which is accurate.

ETA: the downloadable fleet list also says 2000 and Rockwell Colins for the LGW-based 4-class planes. I think the table in the wiki may be mistaken.

Great work on the thread and guide!
