Amex Membership Rewards has launched a transfer bonus to Hawaiian Airlines HawaiianMiles. If you transfers Amex points to Hawaiian by 11:59pm MT on August 31, 2024, you can receive a 20% bonus.
HawaiianMiles are pretty niche but they can be used to book Hawaiian's own flights. Oddly enough, using miles to upgrade to first class (it's really business class), can be a great way to book - especially if there isn't award space.
Of course, if Alaska Airlines and Hawaiian Airlines' planned merger is finalized, you may end up with a bunch of Alaska miles. This is not something I would gamble on currently.
I do not recommend speculative transfers for most people.
