Looking for a flight from LIH-KOA on Feb 23. I was hoping to fly late at like 9pm or so, so that I could have the whole day on kauai.

While there is a flight like almost every hour from HNL-KOA for some reason they all stop at 8pm. Is there a reason for this. It means I have to leave LIH much earlier than I wanted. In the other direction you could fly to LIH, leaving KOA after 8pm.

Also the evening flights are pretty pricey. The last hawaiian flight is at 540pm and is $180. Go is at 630pm and is $142. Only other option is hawaiian at 441pm for $111. These are pricier than I was expecting except maybe the $111 but that is about 4 hours earlier than i would like.

Are there are options I am overlooking. Anywhere I can buy tickets cheaper.
