I know connections in FCO can be a bit time-consuming. On our flight to Italy, we have a long connection time in FCO to Naples so I am not concerned. But on the way back, we are flying Naples to Rome then back to US. We have about one hour and twenty minutes connection time in FCO. I understand that since we are arriving FCO from within Italy and transferring to a non-Schengen/intercontinental flight, we have to go through passport control. But are the lines as long in that direction? This was booked as a single ticket on Alitalia, so I know they are responsible, but I still don't want to miss that flight. Any experience with this?
