Mobile Phones, the Italians love them, I've never seen a Country like it. And I really pity the Cabin Crew on an internal Flight, I've seen the F/A's trying to stop more than one passenger talking on the phone during the Flight never mind switching it off. The afore mentioned passenger needed telling more than once!!!!.
But I must say the Airlines need to tell the Self Loading Cargo the reasons that they are being asked to turn the phone off, as many people dont understand why they need to turn them off.
Posters at the gate/airbridge are a great idea perhaps the Airlines and Airports should get together on this one, sooner rather than later as Mobile Phones arn't going to go away.
