British Airways is continuing its retrofit for the Club Suite product, by them installing the seat on the Boeing 787-8 fleet.

Club Suite has so far rolled out its new A350-1000 and Boeing 787-10, as well as being retrofitted to the Boeing 777 fleet in progress. It offers a 1-2-1 seating layout (thus being a lot less dense than the current 2-3-2 layout in the previous generation Club World seat).
And for those of you keeping watch – yes, the seat has a door.
A total of 12 aircraft are in the Boeing 787-8 fleet.
Whilst it has been monitored in forums and such over the past few days, the news snuck out via Instagram that the deployment was to occur.

In the real world, Club Suite looks quite impressive, being an evolution of a Collins Aerospace SuperDiamond seat.

Look out for further seating changes, as Premium seems to be the word of the day.

Economy Class and Beyond reached out to British Airways. In a statement, the airline said
We remain committed to rolling out our award-winning Club Suite and we’re pleased that our Boeing 787-8 aircraft is next to be retrofitted, allowing our customers to experience our latest business class product to even more destinations across our network.
The airline advises that customers will be able to experience Club Suite on their retrofitted 787-8 aircraft later this year, with the routes the equipment will be deployed on subject to change.
A major improvement
I’ve flown aboard the seat in different guises – mainly with Qatar Airways in the past. The SuperDiamond is a very comfortable seat, that is good for working and sleeping on.
Seeing it deployed further into the fleet – whilst expected – is very welcome news as it will give passengers direct aisle access, whilst disposing on the ying/yang layouts that gave British Airways density in business class.
With a little less density, a superior product has emerged, which for those aboard the flying aboard Boeing 787-8, will be a welcome sight to see.
