The information available is mostly rumours, but United has already given a thumbs up to the design.
- Up to 260 seats single class config
- 7-8 abreast (probably 7)
- 4-5000nm range
All of this is rumours, but I think it is something worth keeping an eye on, as it could be the next serious advancement in aviation, especially since it is expected to be around 60 CFC (carbon fibre composites, not chlorofluorocarbons).
It also appears to be the right width (wide enough for 7-8 abreast, but nothing more, which is good for customer experience (2-3-2 is good)
Not gonna lie that looks quite impressive
