...which you will be able to "enjoy" on Air Cariabes, proudly being the first airline (that I'm aware of) to take Airbus up on their comfy design

ha but yea, this ultra high density config notwithstanding, you're spot on. the standard going forward is 9 abreast A350/B787, and 10 B777x.

Heck, it seems the days of even B77W 9 across economy are behind us especially if CX converts from 9 to 10 across. Already 2/3 of 77W capacity is 10 abreast, and CX is the second-largest operator of the plane behind EK. Assuming 77W sticks around for another 15+ years as the backbone of carriers' fleets, I think it's a matter of time before 77W is 10 abreast everywhere. Alas.

Oh, and there's also the 11 abreast (downstairs) A380 config being marketed too. http://www.runwaygirlnetwork.com/201...d-of-customer/
