Suggests that the economy seats in the 787-9 will be half an inch wider than in the 787-8 (17.3" compared to 16.8") and an inch extra pitch (32" compared to 31"). I've been dreaming of a 32" seat pitch in short haul...
It also states that 18 of the 747s will be refurbished with power sockets at every seat etc. They're not dead yet
