re: World’s longest commercial flight starts tonight

None of the seats pictured in the article are your standard coach seats. Those are all first class pods.

Of course 20 hours is doable in first class.

They won't be able to accomplish this with the traditional seat layout and cargo policies that we're used to seeing. They are probably going to try to do this with 1/4 of the maximum passenger capacity of the Dreamliner.

Flying is all about weight and balance. They're gonna have to load up on a lot of petrol for a 20 hour flight, like, enough for a 24 hour+ flight.

More fuel and less cargo equals less profit.

Any ticket for this ride will be astronomically expensive. But maybe their marketing department sees an opportunity catering to the rich.
