We are one of the 'Remember the Alamo' losers and made a one way trip from Maui to Kauai in mid-July frantically with Hawaiian Air. We paid just under $200pp. Isn't that price gouging in a crisis?
Short answer is no. They are not a monopoly and they have a viable competitor. They are free to set the price to what the market will bear. If you don't want to pay their rate, you're free to choose another airline or another travel date.
