Interestingly enough, when facing head winds the optimum true airspeed for max range/lowest fuel consumption per distance does in fact increase. And the reverse when facing tail wind.

The finnished carbon/resin composite would weight something around 1,4 kg/mm/sqmtr. So a 1,1 kg/sqmtr would be about 0,8mm thick. But you are probably correct that this is way too much for one single unidirectional layer. But a 0,1mm thick layer is only about 100 grams/sqmtr or less of carbon, that ...

So, we see that if about 10.000nm air range is required going west against the prevailing winds then 300 passengers is clearly out of the question for either plane. Even 200 passengers seems to be a stretch but if any plane can do that is must be the B778. But the route will not be flown westbound,...
