Have written a few reviews before - of both B.A & VS, as I stated - IMO there is very little diff in WT and economy between the two airlines.
Not that I take airlinequality.com as the benchmark tool when choosing a carrier as the reviews are in general too short and somewhat simplistic as two examples below show - one of BA & one of VS
Not very attentive Flight Attendants, cabin not well maintained, IFE on the B777 offers few selections, my video programs were wrongly loaded with no flight tracking. The food was not good at all.
The plane was full of people shouting and drinking, we had 4 middle seats and the 8 middle seats behind us were full of these people. They were standing up and pushing against our seats all the time. Their language was awful and none of us got any rest.
