Yep. Hawaiian is toast. A couple of 737-MAX's (are those ETOPS birds really suited to high-cycle operations?) flying 4 or 6 flights a day is definitely going to run HAL's Interisland operation out of business. And that would surely kill the entire airline; not like they make money doing any other types of flying after all! Interisland is all they do, right? If I remember correctly all those international flights, US mainland flying, and cargo stuff is subcontracted out to Delta, right? That extra 10 or 20 flights a day tagged into the middle of SWA's ETOPS pairings will really kill them! Hell, maybe Alaska can jump in and fly some interisland pairings too! Then it would almost be like sharing the market with Aloha again (or half of them at least)!
Have you considered applying at SWA? When we eventually merge and HAL gets stapled to the bottom of SWA, maybe today's HAL captains can be your FO's!
Definitely don't waste your time applying here!
