British Airways pioneered lie flat seats in long haul business class. The seats weren’t wide or private, but they were classy with blue fabric and brown leather. I actually liked the old lie flat business class seat that I flew a decade ago (‘New Club World’) more than the current iteration that feels like a sea of impersonal corporate cubes (‘Next Generation Club World’).
The current seat is well overdue for a refresh. The basics of the current seat began rolling out in 2006.
