One of my customers makes the 'seats' for business / first class seats. Not sure I can call them seats exactly rather than amazingly engineered works of art. I doubt I could ever afford to sit in one on a flight but the showroom models I have tried are almost a comfy as my sofa. Flatscreen TV, motorised adjustment, some of them even turn into a small bed. They also weigh less than my office chair.
As stated in the article give it to cattle class, the only issue being the lack of USB chargers in the cheap seats. If it has noise cancelling headphones :o
