Need 6 tickets for a flight from HNL to LIH. Ticket cost is $124 each on Hawaiian airlines. I have 300K AMEX MR points and 200K AA miles. AA is showing availability for the same flights for 7500 miles/ ticket. Question is should I use the AMEX points (and swap my pfd airline to Hawaiian) and get 2 cents/ dollar for MR or use the AA miles for an effective 2 cents. Adding to question - i know that if i sign up for the Hawaiian miles plan, I can get $10 off each checked bag if I book with AMEX vs on a mileage ticket.
