Aircraft cabin, one of the first tangible features of an airline that has a direct connection with the passenger. As soon as a passenger steps inside an aircraft, the first noticeable aspect is the cabin interior, the hue and colors, the mood-lighting.
then slowly as the passenger makes his way towards his seat, the next feature that is in direct contact with the passenger is the seat cushion/cover, the Wi-Fi connectivity, In-Flight entertainment, the headphones and goodies (if any) that are placed in the seat pocket.
