I don' think that it is realistic to expect people to get airway charts out and plot a route and superimpose spot winds for airports not necessarily on the route and come back to you with a best vertical profile
What we have done is to give you the basic principles and the ammunition to do that youself.
So go and do it
[BTW: what has the aircraft type got to do with it - it is only a fuel burn number that plugs into the equation - furthermore, while BA aka GSS may fly the route, they certainly don't operate A330's]
