While better than having a neighbor, I'm not a fan of the polaris seats on the 787s! I'm relatively thin and can sit comfortably in Y, but I find the seats on the 787-10 to be a bit uncomfortable!
Really wish they could have come up with an updated revision instead of using the same config as the 787-10s!
On the other hand, PremiumPlus on the 787s is very spacious and probably the best among the fleet! Good to see they kept it the same.
