Implicit in the quote you posted is that it is a Hwaiian-issued ticket. as marketing carrier, they have opted to collect baggage fes both ways for a Hawaiian Air flight originating in HNL. If you look a little farther, you'll see that Hawaiian may not accord passengers the same baggage fee exemptions doled out by their partners. To make ot simple, just read it as "if you're checking in for a Hawaiian -operated flight, UA's frequent flyer baggage fee waiver does not apply. Hawaiian will collect, no matter how you decide to misread their rules.
