This means luggage handling, and I had such a classic Naples experience on my flight to and from Madrid I had to write about it (luckily no more emergency landings thank goodness!).
On the way there, someone's luggage fell off the little car thing they brought it over the road on, and people noticed but they just left it there... some poor tourist must have arrived with no baggage!
On the way back, the pilot landed and said that they were just sorting out the staircase on the door of the plane, opened the door and the staff at Naples airport had put the staircase about 5 feet away from the door of the plane. The woman next to me rolled her eyes and said "Napoli..." and I have never felt more spiritually close to a stranger in my life. Haha...
