Oh, so many options depending on the OP’s youth and need for TPs.
Our last trip was JER-UK-DUB//DUB-CLT-LAX//LAX-OGG. So 2 night-stops outbound, and a heavy 36-hour run home. I could do it in my early 70’s, so not impossible - just a bit tiring
Oh, and a lot of Domestic First without lie-flat.
c. 1,000 TPs, IIRC, which was useful! TR on our last OGG trip in my signature if you want to dig into details.
Edit = ahh, starting in Cork. Delete some TPs and one night stop. Other suggestions sound better!
