Hawaiian Airlines HawaiianMiles members can earn 20,000 bonus miles with a new credit card issued by Bank of Hawaii. The Platinum Hawaiian Airlines Visa card comes with a 20,000-mile sign up bonus after first purchase, an annual 2,000-mile bonus on your card anniversary, two miles per dollar spent on Hawaiian Airlines tickets and one mile per dollar spent on all other purchases. You can earn additional miles with HawaiianMiles XtraMiles partners. Cardmembers also receive a 50 percent discount on a companion ticket valid for travel between Hawaii and the mainland U.S. The card is similar to the existing Bank of America Platinum Visa card that is also offering a 20,000-mile sign up bonus. Sign up for both cards and you’ll earn 40,000 miles — enough for a roundtrip ticket between the mainland U.S. and Hawaii.
