Wanted to better understand which of the 2 ITA lounges I would use for the following 3 tickets:

FCO-ZRH
FCO-CAI
FCO-LAX

The ITA website says the PIazza di Spagna lounge is for intercontinental but also for flying to Schengen countries. It lists the Hangar lounge for domesti as well as flying to Schengen countries.

From what I see the food & offerings are better in the Piazza di Spagna lounge so what I was wondering can I use it before the ZRH flight ? I read one blog making it sound like it was only for overseas, thus contradicting the website.

Is it worth going to both or which would you all say is better?

Thanks
