This seems to be a matter of UA being cheap. Even twice bankrupt USAirways has a contracted lounge. ..and yes, both UA and US use the same terminal, terminal C. The contract lounge is call "L'Anfore" it has a nice cappucino bar, since that seems to be all I care about when leaving Italy.

Add to that the fact that US has dayrooms at the Fiumicino Hilton reserved on arrival for all business passengers, a very nice touch and good way to start your day.

These were of course started long ago and if current managment in Tempe found out they'd have a heart attack. But come on UA!!!
