Each pair of seat units includes an aisle-seat unit and a non-aisle-seat unit. The longitudinal axes of the non-aisle-seat units are arranged in-line with one another, and the longitudinal axis of the aisle-seat unit of each pair of seat units is angled so as to provide a passenger access path linking the non-aisle-seat unit of a pair, with the aisle.
