May on the Kona Coast features farmer’s markets, cultural celebrations, and smaller music or food events perfect for visitors arriving at Ellison Onizuka Kona International at Keahole (KOA).

May is a shoulder season month offering excellent value for DEN→KOA travel: fly mid-week (Tuesday–Thursday) and choose off-peak times (early morning or late evening departures) to find the best combination of price and seat availability. Booking 4–8 weeks ahead is often optimal; last-minute fare drops can occur but are less reliable. Avoid traveling the Memorial Day weekend if you're price-sensitive, as fares often spike around the holiday. For better comfort, book aisle or bulkhead seats early, and consider a premium economy option for longer nonstop flights.
Direct (nonstop) flights from Denver International Airport (DEN) to Ellison Onizuka Kona International at Keahole (KOA) are faster and reduce connection risk, but they can be more expensive and less frequent in May. Connecting flights via LAX, SFO, or SEA typically offer more schedule options and lower fares; however, they add layover time and increase the chance of missed connections. If you prioritize speed and reliability, try to book available nonstop seating early; if price and flexibility matter more, choose a one-stop itinerary with a minimum buffer of 90–120 minutes for international-style connections. Use airline-provided minimum connection times as a baseline and add extra padding during holiday weekends.
