Hawaiian is probably the most nepotistic airline out there, and they heavily favor locals/Hawaiians. Most of the Caucasian pilots there also seem to have roots in Hawaii. They probably aren't too interested in someone wanting to commute from Dallas. Jumpseating/nonreving is hard enough once a year for vacation on a flexible schedule, do you really think that's a good idea on a regular basis?

There are also a ton of Aloha and JALways guys that are probably being given first crack at the interviews, just a guess.
