I have the HA Barclays MC. The T&Cs say:

• The Hawaiian Airlines Mastercard Primary Cardmember is eligible to receive 2 free checked bags on Hawaiian Airlines operated flights. Authorized users of the Primary Cardmembers’ Card Account do not qualify for the free checked bag benefit. This is only for travel between North America and Hawaii and between Neighbor Islands (interisland). International flights are excluded.
• All ticket purchases (original and exchanges) must be made with your Hawaiian Airlines Mastercard.
• Ticket purchases must be made directly from Hawaiian Airlines (HawaiianAirlines.com, Hawaiian Airlines Reservations department and Hawaiian Airlines airport ticket counters) to qualify for 2 free checked bags. Tickets purchased from third parties (i.e. ID90, travel agencies, etc.) are not eligible.
• The Primary Cardmember must provide their HawaiianMiles Program Account number associated with the Card Account within their reservations any time prior to check-in. You must be a current Primary Cardmember upon check-in to be eligible.

So if I book an interisland flt using miles, on the HA website, and pay the taxes with my HA MC do I qualify for 2 free checked bags or do I have pay $$ and put the entire charge on my HA MC?
