I just signed up for the HA Mastercard that comes with the one-time 50% off companion ticket. The fine print says:
When booking your flights online, be sure to select 2 passengers. Both passengers must book travel on the same flight record, fare and class of service and must travel on all flight segments together. Primary cardholder must be one of the passengers on the flight record, and tickets must be purchased with the Primary cardholder's Hawaiian Airlines World Elite MasterCard.

Does this mean I can't buy the first ticket using points? Do I need to charge the price of both tickets (100% of ticket 1 plus 50% of ticket 2) to my Mastercard?
