Except MCO is a pure price market and the flights are relative short for WN to and from MCO vs HI. The Hawaii customer is different than the MCO crowd. The trip to Hawaii may be their only trip there in a lifetime.
WN is going to need to evolve on the service end to do well in HI markets.
But wait, half the people in this thread claim that fares to Hawai'i are already super-low. Are you saying that's not true and that it's not a price-driven market?
We also have numerous claims that customers are already loyal to HA and AS and have their credit cards for the free checked bags -- are these the customers taking once-in-a-lifetime trips?
Carriers like UA have "evolved" their service to Hawai'i so that it's basically identical to what WN offers on a flight like DAL-HOU or LAX-OAK -- a non-alcoholic beverage and a bag of snack mix/pretzels -- except that UA offers snack boxes and meals for an additional upcharge. But apparently WN plans to offer complimentary snack boxes on the Hawai'i flights which will likely be comparable to what's available on UA for the bargain price of $9.59.
AS has assigned seats, premium economy, first class, power at every seat (AC and USB), multiple meal and snack options, mileage redemption with over a dozen airlines worldwide, Satellite wi-fi with over-ocean and streaming capability for customers currently being installed.
And most of these things carry an extra charge. Not every passenger wants to be nickled and dimed on their way to or from their vacation.
