Summary: The benefits of flying aboard this newer style of aircraft are nearly forgotten the moment you sit down. The only reminder being the big window and the ability to stand up without jamming your skull into the overhead. The plane brings benefits you can’t see though, like cleaner air, better pressurization and lighting designed to help you feel refreshed when you get to your destination and better insulation from engine noise.
As I and others have noted - window seats are especially tight. When viewing the video I invite you to pay particular attention to the placement of the armrest and seat cushion against the sidewall of the airplane. Then, next time you're flying, do the same on an Airbus. Crazy how a domestic plane offers more personal space.
