Alitalia, an early flight, and the dreaded Terminal 5

Hi friends, I have been reading up on Ron In Rome's fantastic blog, and am hoping he, or someone, can help with my question.
Ron states that "US flagged flights" all fly out of T5, and that they do not leave before 9:30AM. Does "flagged" mean any flight headed to the US without an EU layover; or that they have to be a US based company? (or something else?). I fly Delta operated by Alitalia, from Rome direct to LA. My departure time is listed at 9:15AM. Does this sound like a T5 departure? Thanks, Cat.

"operated by Alitalia" That's the key phrase. The answer is no. Your flight will be out of T3, not T5.

I concur. It's T3.
You are flying Alitalia, not Delta. Delta is only the code share.

US flagged flights means US flag flights, which means aircraft with US flags on them, in other words operated by US carriers.
