Chilling on a beach in Hawaii isn't a bad way to spend a week in the fall. You might think, "That's not for me. That's for people who photoshop their Instagram pics." Not so. Deals on flights to Hawaii are becoming increasingly frequent. Right now there are cheap fares from Alaska Airlines and Hawaiian Airlines (as well as a couple from United and Air Canada) that will get you to Honolulu for less than $400.
The deals are mostly from west coast cities in September through November, but there are a lot of cities that have good prices. At the low end, you can get roundtrip tickets for $348 from Portland or $349 from Las Vegas and Seattle.
Other cities that are in luck include Edmonton ($337), Vancouver ($350), San Jose ($359), San Francisco ($377), Calgary ($386), San Diego ($429), Reno ($447), Los Angeles ($448), Eugene ($474), Missoula ($482), and Boise ($484).
