To guide a passenger to the general location of his assigned seat in an aircraft cabin, the cabin is divided into several cabin zones that are individually identified by different colors of illumination, for example a yellow cabin zone, a red cabin zone and a blue cabin zone. Each service class can correspond to one cabin zone or encompass plural cabin zones. Lighting devices arranged in the cabin are activated to provide illuminating light having the appropriate allocated illumination color in each respective cabin zone. The lighting devices are preferably ceiling lights, sidewall lights, and/or window funnel lights, controlled from a flight attendant panel via a lighting controller. A passenger ticket displays the passenger's assigned seat number and letter, and also the color of the cabin zone in which the assigned seat is located.
