EWR-NRT in Y, NRT-HNL (open jaw) LIH-LAX-EWR in J at 100K UA miles x2 ppl.
(35K for outbound in Y, 65K for inbound J).
The J availability for hawaii -> nyc was hard to piece together, especially since I wanted to get a 24h stopover in LAX or SFO.
Spent 1/2 and hour on the phone with United getting that done. I booked the return on a different date with better availability, then had them change the HNL->EWR leg to the above routing.
And it turned out that the website was showing phantom J availability on some dates
Ended up doing the open jaw, so need to get an island hop - trying to decide whether a mileage ticket is worth it there (6k UA) or just buy it for $84.
Would Hawaiian charge for baggage for inter-island UA award flight?
