Pro picture of BA business class:
2-4-2 configuration. You can clearly see that the facing passenger has to climb over the opposite passenger's feet once he has lowered his foot stool. A foot stool you have to manually lower and raise, but cannot be reached when belted into your seat. Also note the silly foldaway table with nail-breaking release, and folding monitor that cannot be used during takeoff nor landing. The aisle seat blocks FA access to the window seat, so food is constantly passed over you to that passenger. He is facing backwards, staring right at you as this pantomine is performed regularly throughout the flight. Neither of you has much room. Whether aisle or window, you are either leaping over someone or being lept over. Aisle denizens also get no privacy at all and are forever being bashed by passengers and trolleys traversing the narrow ribbon between you and the adjacent seat.
Compare with my amateur pic of Air Canada:
No neighbour at all. 1-2-1 so everyone has an aisle. Twice as much space as BA. Here I'm checking the flight progress on the capacitive touch screen remote, while the film plays on the main monitor:
And some seat adjustments for mattress firmness, lumbar and neck support, and massage option via its own separate touch screen:
It's not the gadgets though. It's the feeling from BA that everything is cost minimized, passengers per square foot maximized, discomfort be damned. That they persist in calling this brazen insult a "Club" as though it offers some calm oasis for the more discerning is an absurd affectation.
