We are away at present, so this article is shorter than I would like. However, I thought this story on Australian Business Traveller was too good to wait.
It explains, in detail, a potential new Club World seat which British Airways has just submitted for patenting. It is potentially designed to launch on the upcoming A350 aircraft but would also be retrofitted on other planes.
The revelation is a potential move to a 1-2-1 formation, at long last, albeit with some design compromises.
What is not in the Australian Business Traveller piece is a link to the actual patent application itself which you can find here.
There is more discussion at Flyertalk here.
