Frequently asked questions

Is it cheaper to buy a plane ticket from Ellison Onizuka Kona Intl. Airport at Keāhole to Harry Reid Airport (formerly McCarran Airport) last minute?
Booking your journey from Kona Intl. Airport (KOA) to McCarran Airport at the last minute could save you dollars if you happen to find a real bargain. However, fares usually don’t drop in price as the date of departure nears. If you wait around, flights could also be booked out or the best seats gone (hello, middle seat!). If you’d rather err on the side of caution, book well ahead of your departure date. Don’t forget that some of the biggest bargains can be found up to 12 months in advance. If your preferred airline hasn’t released its airfares yet, check back regularly as offers are updated on Expedia constantly.
