Emailed them from their contact us portal. Took about a week or so. I shared my Delta status. They asked for additional details. All my flights with Delta in 2020. I shared that but also shared that I hadn't traveled much recently due to COVID. They wanted to see that I’ve flown on routes they service. So, I went back to 2019 and 2018 and shared several flights to Hawaii, Japan, Korea and Tahiti, to show that I do travel on routes they service and I’m willing to travel on Hawaiian Airlines in the future. Below is the email I received.
