Shame, it's a beautiful kit. Plus the 747 has personal air fans to tune your cooling. The modern planes tend to have done away with those, meaning you're usually too cold or too hot.
I also like the business class ANA 787 bathrooms with the washlet (bidet) toilets.
Before this, flew Mid East carriers (Etihad, Emirates, Qatar) and they all had those vents.
I think it’s specific to an airline .
