Flew from Hawaii to LA, LA to Houston, and Houston to Buenos Aires. Had an overnight there, then took a flight chartered by the cruise company, from Buenos Aires to Ushuaia, the port where the ship docks. I dont know what the “seat pitch” was, but I could touch the front of my seat with my thumb, and the back of the seat in front of me with middle finger, at the same time. Had to sit nearly 90º sideways for 3 ½ hours. I’ve been on cramped flights over the decades, but this one just might top the charts.
