Hi,
I have a trip planned for early June going one way from Rome to NYC and then NYC to HNL one week later.

This is what I have to work with:
55k British Avios
70k United miles
70k Chase UR points

Looking at cash flights, I found $250 for Air Berlin, Rome to NYC with 1 connection - which seems unbeatable. And then $520 for a direct flight from NY to HNL. So the value seems a lot better for using miles on the NY-HNL flight - however, the best I saw for that was 45k UA miles.

I heard it's possible to do layovers with UA award redemptions, is that right? Is it possible for me to get decent value on economy/business/first award redemption from Rome to NY to HNL?

Or are there any transfer partners with Chase for the NY-HNL flight? I was used to paying 17,500 with AA, but have few AA miles left now. 45k for a domestic economy reward with UA seems pretty bad in comparison.

Any help/tips/thoughts on how to plan this would be appreciated. I'm actually starting in Dubai before Rome, if it's possible to do 2 layovers along the way to HNL.
