Alohabuzzz,
Since you're looking for specific itinerary help, which isn't really allowed in this forum, I'm going to move this to TravelBuzz.
itsme - as for your question, I believe Fiumicino helped answer it - I believe once the price goes down, you can also call UA reservations. I've only had to do this once & it was on NW and they did not charge me any sort of change fee at the time - they issued me a credit for the difference.
