It has nothing to do with the model of aircraft.
I’m sorry but it has ‘everything’ to do with the ‘model of the aircraft’.
It’s designed to be a cheap way to haul a lot of passengers on short trips of a couple of hours.
No airline is ever going to configure one to be super comfortable. Any airline version of a ‘neo’ is not going to be very comfortable.
That’s all I was saying.
Thank you for proving my point.....the airline decides the configuration.
An Airbus Neo could be configured any way the owner desires.
It is not a product of the aircraft model, but a decision by the owner.
