A seating arrangement in an aircraft passenger cabin includes rows of seats, one behind another at a prescribed seat pitch. A wider transverse aisle is formed between successive seat rows at a normal exit or an emergency exit. At least one seat row bordering on and facing the transverse aisle is equipped with foldable passenger seats that each have an upwardly tiltable seat bottom and armrests. By tilting up the seat bottom and the armrests, an enlarged width of the transverse aisle is provided in the event of an emergency evacuation. In normal operation, the prescribed transverse aisle width does not need to be maintained, i.e. can be reduced, so the seat bottom and armrests are tilted down into the normal-use position for a passenger to be seated on the seat. Thereby the seat pitch of this seat row can be reduced and the total seating capacity can be increased.
