Espada , 2 years ago , we noticed that we had to bend down to look out of the windows on an American 737-800 . Mmm I thought , didn't have to do that on company 737-200s , 300s , or 400s . The fuselage barrels are the same from -100s to Max series , so very odd . Then it clicked , I'm guessing that the seats are higher off the floor than previous series .... Thus giving more apparent legroom with a higher density seat layout , i.e. seats closer together !
Well that's our thoughts on it .
