The answer to your original question is yes Virgin's on-line seat charts are basically correct. However they only display a generic seat map for their A340-300/600'S. I think this is partly because Vs frequently swap A340 types (especially to the US east coast) according to demand. Also only 60% of seating will ever show as this is the maximum amount that VS
, and indeed most other airlines, will pre-allocate.
Also it was earlier mentioned that the last rows have narrower seating and less recline. This is not strictly correct. The seats are exactly the same size throughout the cabin. The cabin does narrow towards the back, but you also lose a seat in each row so there is no compromise with regard to seat width. With regard to recline, it is only the last row (64-65) That has limited recline.
Below are the seating numbers for each repective aircraft:
A340-600, Economy rows 31-65, excluding rows 48-50 (there is a row 47!)
A340-300, Economy rows 41-65, (no exclusions)
Hope this helps,
So long 701, it was nice knowing you.
