Try justfly.com has the most reasonable prices for flights. I’ve found tickets as cheap as $327 from San Diego flights from LAX are a little more expensive. If you are coming from other regions of the US the prices can be more expensive. A good price is anything under $400 from the west coast and $600 from other regions.
AirBnB has some nice deals. If you book on AirBnB please make sure you are close to the Kona area as the wedding will be at The Sheraton Kona.
We would be delighted to see you there, but if you can’t come we understand. We will have a number of events before and/or after the Hawaiian ceremony, so hopefully if you can’t make the wedding you can attend one of the other events.
The ceremony will be in a chapel on the beach, so semi casual wear is great!
