No surprise here. When it comes to having Aloha Spirit Southwest eats Hawaiian's breakfast, lunch, dinner and desert. So much more customer oriented, more value for the money.
.
On Southwest you can change your flight at anytime with no fees. Only pay if there is a difference in flight fare cost.
.
Need to cancel? No problem. Follow the rules and cancel with no charge. Your money held online to use for your next purchase.
.
Two free checked bags is where Southwest buries Hawaiian. Especially when HA frequently charges you again if you have to recheck the bag.
.
Yes, HA will always be a follower, never a leader. HA management bureaucrats haven't got a clue. Only interested in nickel and diming  passengers for every cent they have.  It's what they do.
