Cancelled flight and lost first class seats on Hawaiian… what compensation is reasonable?

Booked first class seats on Hawaiian Airlines from SEA to HNL. After a delay at the gate, the flight was ultimately canceled.

We were rebooked on a later flight, but only in regular economy, not even premium. Between losing first class, the delay, and missed time in Hawaii, it feels like a pretty big downgrade overall.

For anyone who’s dealt with Hawaiian (or Alaska handling rebooking), what’s reasonable to ask for here? Refund of the fare difference, miles, travel credit, something else?

Appreciate any insight.
