Via One Mile at a Time United has entered into a codesharing agreement with Hawaiian (now that former partner Aloha Airlines has ceased operations).
Aloha offered both another avenue for redemptions to the Islands. Now there’s Hawaiian, which partners with just about everyone else in the US so I can’t imagine redemption seats are easy to come by, but perhaps the gap that they’ll fill for Mileage Plus members is the ability to use Mileage Plus miles for intra-island flights.
I’m not yet aware of the details of the partnership, whether or how you’ll be able to combine say United across the ocean to Hawaii with Hawaiian’s intra-island flights on the same award… Or what the cost of standalone intra-island awards will be (Aloha was a great value at just 5000 miles).
It doesn’t make up for the United’s increased change fees, award booking fees, and elimination of 500-mile minimum accrual on short flights. But good news is good news!
