It's no surprise that West Coast states offer the cheapest flights to Hawaii, with California, Washington, and Oregon leading the way. In fact, most of the top 10 cities are in California (with two notable exceptions: Bellingham, Washington, and Salt Lake City, Utah.

California remains the cheapest U.S. state to fly to Hawaii from in 2026, primarily due to its geographic proximity and the high volume of "West Coast-to-Hawaii" flight paths. Major hubs like Los Angeles (LAX), San Francisco (SFO), Oakland (OAK), and San Jose (SJC) benefit from intense competition between airlines like Southwest, Hawaiian, Alaska, United, and Delta. It is common to find round-trip fares from these cities for under $300, and occasionally as low as $199 during seat sales. Other West Coast states like Washington (Seattle) and Oregon (Portland) are also very competitive, but California's sheer number of departure points usually keeps its prices slightly lower. If you are flying from the East Coast or the Midwest, you will almost always see significantly higher prices due to the fuel costs of the 9+ hour flights. For those living in the middle of the country, it is often cheaper to book a separate flight to a California hub and then a "commuter" flight to Hawaii rather than booking a single through-ticket.
