All true, but it does adversely impact pax who don't have the peace of mind to change given the uncertainty they too face with the potential hurricane. I know a few who are hopeful HA issues a weather waiver and are frustrated that other pax on other carriers (I am in this latter boat) have been able to take advantage of waivers and don't have to gamble. It's not just for ops as the proactive weather waivers are customer friendly (whether intended to be or not). IME, it's short sighted on the part of HA to take a chance on its pax travel plans.
As you well know, Hawaii is the center of Hawaiian's operation. Hawaii is merely a few spoke stations for the other carriers. Hawaiian can spend the time to focus on the real impacts of a storm, as it will have ripple effects for the entire airline. The other carriers can easily cancel or delay a few flights to mitigate the problems a storm of Hurricane or even tropical storm magnitude will incur. Recovery for them will be far easier. What good reason would HAL have to offer weather waivers for travel to islands not affected by Madeline? Or any storm for that matter? IMO, HAL is taking the right approach. If the weather will adversely affect the operation and compromise safety, they will act accordingly. Until then, it's speculation and issuing blanket weather waivers without know the full impact of the storm is unnecessary.
