Not a priority for them.......One HUGE issue about the airplanes they use in general, engine time to cool down.  Inter-Island flights are too short for engines to cool down before next departure.  Which will result in either lots of maintenance issues or possibly longer inter-island flying time.  That is why Aloha used 737-200s and HAL uses the type of aircraft  with that type of jet engine that can handle the short segments multiple times a day.  So it'll be interesting to see if the even start inter-island flying.  Maybe as a short "tag" flight, for example:  LAX to Maui then to HNL.  Because in between the arrival in Maui and continued flight to HNL, the engine has had the time to cool down.
