Having 7 classes is just an overkill imo. It's like my BMW having so many ways to personalise the ride and drive, with barely any noticeable differences. All the extra complications will likely result in customer complaints and costly maintenance, as we all know that electric seats are never as reliable as mechanical lever controls. The sleeping pod idea was a good effort to make lie flat affordable to the passengers in the back, but absolutely not the best use of scarce capitals and limited spaces on a plane. I've a far simpler solution that involves zero additional investment and takes up no additional spaces, but will obviously not give it away for free lol. On top of likely problem getting people out of the pod crew might even have to manage complains about bad odours from previous occupant. I'm guessing the crew will replace the bedding each time but this could just end up distracting them from their main job, which is to feed and water the passengers LOL.
