Airfare deals are typically only available on limited dates. We recommend you use Google Flights to find dates to fly, then book through an online travel agency such as Orbitz or Expedia, which allows you to cancel flights without penalty by 11pm Eastern Time within one day of booking. However, if you’re using the American Express Platinum Card, you’ll need to book directly with the airline or through Amex Travel portal to get 5x MR points. Remember: Fares may disappear quickly, so book right away and take advantage of Orbitz or Expedia’s courtesy cancellation if you’re unable to get the time away from work or family.

In case you haven’t heard, there have been a lot of deals to Hawaii recently. We were blown away in December to see airfares to the 50th state dropping into the $300s round-trip. But, the crazy part is the deals keep coming! Today, we’re seeing 19 mainland US cities to Hawaiian airports for under $400 round-trip.

Tickets are generally available from February through May and then again from August through December, though exact availability will depend on the route, of course. You don’t need any tricks to get these airfares. Just find the dates you want by searching with Google Flights, then book on Orbitz, Expedia or directly with the airline itself.
