Just back from Rome yesterday and have a tip for those flying into and out of Leonardo da Vinci (Fiumincino) Airport — you can take the new Alitalia Bus for 7 euros each way to and from the airport. But you have to be flying on Alitalia (a plane ticket is required to purchase a bus ticket).
I’m not sure exactly when the bus service started but the “New Alitalia” as the airline has been rebranded is heavily promoting the service. There was an advertisement on every seat on my flight from FCO to EWR yesterday.
One minor point of inconvenience for those flying from the U.S. is that the bus is based in Terminal 1 and U.S. flights arrive in and leave Terminal 3. There is a shuttle bus that runs between terminals however.
The bus make stops at several spots in the center of Rome including Termini Train Station is a very affordable new airport transportation option. I’ve dropped a note to my contact at Alitalia to learn more about the new bus service.
