hmm interesting! I’ve always understood it as the A359 is more efficient on longer routes because it can lift more over a longer period but because the 789 is lighter on shorter long hauls it’s more efficient as I’ve understood it.

with the A35K it depends on your network and capacity. The 35K on a London to Singapore would be MUCH more efficient than a 78X but on a London to New York the 78X would be much more efficient. They’re both very efficient but have different roles to play.

here at BA because most of their long haul to short to medium long haul the A35K’s appeal is its payload relative to its efficiency. It’s extremely efficient and lifts just as much as the 747. The 787-10 lifts almost as much but because it’s about 20 tonnes lighter it burns significantly less fuel. In BA’s 4 class sits about 260. If you put the A35K in a 4 class it will sit about 290. So about 30 extra passengers. So it really depends on what you want. They’re both fantastic at what they are needed for.

looking ahead at the 777-200ERs the 787-10 seems looks a top contender for that contract
