It is an open secret that the Boeing 787 is by far the most fuel-efficient plane on the market. Per seat, the Boeing 787-10 would come out ahead of the A350-1000, but as the A350 can carry more passengers, this may negate any savings made unless the 787-10 was in a dense configuration.

Is Boeing 787 same as Dreamliner?

We know them all as the Dreamliner, the aircraft that basically kicked off the current generation of air travel, building upon the twin-engine long-range revolution.
