All I can find is that Edward was not with Carlisle and Esme with the Denali Coven. Alice tells Charlie that she had last heard from Edward when he was in South America but we don't know when that was, just that he checks in every now and then. We do know that he was trying to track down Victoria and didn't answer his phone after talking with Jacob.

It is possible that he could have been somewhere where he could quickly catch a short flight to Italy at an international airport, plus if he ran at vampire speed from the airport and saw the Volturi immediately the story is more plausible. That being said, yeah plot holes happen especially if you don't research what you're writing or make it clear to the reader. Timeline is crucial to the storyline.

Hope this helped.
