The website now has a projection for Hawaiian airlines. Even though the projection is lacking mandatory retirements (if anyone has mandatory retirement numbers for Hawaiian please let the website know.)
Fortunately there is enough information out in the public space to allow a projection based on fleet plans for the next few years. Feel free to take the time to explore the websites Hawaiian Airlines pilot demand page. You will also find a link in the right corner to the 2030 projection and in the middle of the page a link to the fleet projection.
On the fleet projection page just click the updated date for each fleet type and a window with the source or reasoning behind it should pop up. Enjoy!
