Wonder how emissions/seat/km on representative routes differs from the larger planes?

Given that landing and takeoff is particularly bad for emissions if you're avoiding a change of planes I guess that might be a win ? Not as big a win as not flying but better ...

Given that the first example they give is NYC-LON it's a question that interests me.




I find the other trade off (against the extra fuel consumption from each takeoff and climb) interesting. Additional fuel is consumed to carry the weight of the additional fuel required for a longer range (and so that is recursive). For example, under the Weight - Flight Distance heading of the Fuel Economy in Aircraft Wikipedia page, it notes that for trips above 3000 NM, it is more efficient for a 777-300 to make a stop for refuelling.

the issue with big planes is that they're more efficient if you fill them up.

with 747 or 380 sized planes that was always a tenuous proposition at best. if it's not full it's still burning the fuel to lug its heavy big self around.
