Is there anywhere at FCO one can store luggage for 18 hours or so? We will be returning our car to FCO and taking a UA flight the next am. Are there any storage facilities? Or is it possible to check in at UA the afternoon before our flight.

There is a left luggage facility in Terminal 3, at the arrivals level. It's open from 6:30 to 23:30 and it costs 6 euros per bag per day (24 hours or a fraction thereof).

When I try to find the page in English, I get a page not found message, but you can run it through translate.google.com :

Or maybe if you open www.adr.it it will come up in English and you can navigate to it: Airport services/baggage deposit and porterage.

Thanks, Sandra, I couldn't get there from here! The main page comes up automatically in Italian for me, because my OS is Italian. When I switch to English, it returns me to the main page in English, but then when I click on "services in airport" I get a broken link.

Thanks, very helpful. Any ideas how much time to allow from Piazza Navona to FCO for a 10:50am United flight?

You asked this question already on another thread. How are you getting to the airport? If you're using a car service, they'll tell you when you should leave. If you're taking a taxi, you also need to tell us the day of the week.

Finally, it also depends on where your flight is going. I assume, since it's UA, that it's a direct flight to the US. Direct flights to the US on a US carrier require at the very least an hour more than flights to other destinations. Since the most recent terrorism alert, you should be there 3 1/2 to 4 hours before scheduled takeoff.

Yes, I know I did. I asked specifically about time. I then added the question here since you two seem so knowledgable. Sorry if the duplication annoys you. I appreciate your responding.
