Hi All - sorry if this has been posted before (I tried searching here and across FT and didn't see anything).

I'm planning to fly between islands in Hawaii using miles. My most likely routing is KOA-LIH. I know there is a nonstop flight but I'm curious if I can book a one-stop in HNL and make a day trip out of it. I.e. take the first flight in the morning KOA-HNL and then a late evening flight HNL-LIH.

The Hawaiian Airlines website doesn't show this as an option (it caps at ~2h layover), but does show availability for the individual flights on separate itineraries. Will I be able to call in and request a one-way redemption with a long (~12 hour) layover?

Thanks!
