Connecting at FCO but Arrival and Departure ticket are not o
My wife and I are planning a September trip to Italy. Our return flight departs FCO at 10:40AM. Our arrival time is planned for 7:40AM the same day. The tickets are not booked together and we have 2 checked bags. Is it possible to arrive on Alitalia at 7:40AM (likely Terminal 1) collect our bags then check in at United, go through security and make a 10:40AM flight to the US (likely Terminal 5)?
Any help would be greatly appreciated. Other option would be to arrive in Rome the previous day and stay near or at FCO. Would rather not stay the night.
