The Bank of Hawaii used to issue the Hawaiian Airlines credit card with a sign-up bonus of 35,000 miles. I have made use of that offer last year.
Now Barclays has taken over and offers a 35,000 miles Hawaiian Airlines card again.
Note that the annual fees is not waived.
This new offer also comes with a companion ticket on Hawaiian Airlines between North America and Hawaii.

Now my Hawaiian Airlines account got 2,000 miles credited as annual bonus for the BoFa card and the companion ticket certificate became available as well today (though I can't remember that as a benefit of this card previously).
The 50% discount is actually pretty useful. HA does not use high fuel surcharges so the ticket price is actually being reduced.
For the example below the ticket price is $266.90 + $198.92. This is a normal price for SFO-HNL. The 50% discount would reduce the fare portion of the second ticket from $465.82 to $232.91 + fees.
It's not as good as the BoFa Credit Card Alaska Airlines companion ticket but then again Hawaii has a different route network than Alaska.
