Delta from Fco

Arriving? Departing? Is the flight to/from the US or to/from another Europen location? Most departures back to the US without going to another EU airport first need you to check in at Trminal 5, after clearing security they usually transfer people back to Terminal 3 for the actual boarding. Arrivals are usually at Terminal 3. Is Delta the operator or just code share for either Air France or someone ele?

I will be departing ...so I will need to go to t5 first? And thanks

May not be a correct assumption - It depends. IF it is an international flight directly back to the US, then it is T-5 However, IF it is a domestic flight connecting to another airport in Europe for your direct flight to the US, then it is the regular terminal, probably T-3.
