The first passenger seat is situated next to the first aisle with a seat direction parallel thereto, and the fourth passenger seat is situated next to the second aisle with a seat direction parallel thereto. The seat direction of the second passenger seat is angled by at least 2° relative to the seat direction of the first passenger seat. The seat direction of the third passenger seat is angled by at least 2° relative to the seat direction of the fourth passenger seat. The first and second groups are next to each other, and have a longitudinal offset relative to each other along the longitudinal axis.
