Hawaii-based Airlines - Already booked HA flight but would now like to use current discount offer. Possible?

I recently booked a flight for myself and my girlfriend from the mainland to Maui, I just realized part of the promotion was...

"One-Time 25% off RT travel discount between the Mainland U.S. and Hawaii for you and a companion† "

I have never had a HA credit card, what are the chances that I could get them to give me a credit on my account for a trip that I have already booked if I apply for the promotion now? If so, how would I go about doing this?

Thanks,
J

you have tickets?....w/ a cc, you can get 25% off 2 replacement tickets?....if so, you could cancel the current tickets, & use whats left after fees on the new tickets.....

if you post the tickets you have with $, you can get help w/the costs....

I believe the tickets were nonrefundable, so I don't know that canceling is an option??

Hawaiian doesn't have a 24 hour cancel period like other carriers (although for trans-pac reservations, you can place a 48 hour hold, IIRC, per the the CoC), so you may be SOL. If anything, trying to get them to honor the certificate retroactively will be made infinitely more difficult by the MNL call center, which is powerless to do anything more than sell and change tickets.

I'd say chances are zero.

Bummer, thanks for the quick responses! Live and learn, live and learn!
