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 Platinum Card® from American Express, 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.Hawaii’s on sale from all over the US, with tickets starting as low as $317 round-trip from Phoenix (PHX)! Both American and United are attacking Delta hubs at Atlanta (ATL) and Detroit (DTW) — and Delta jumped in to defend its hubs. So, you have your choice of any of the three, and you can even fly right on to Maui at Kahului airport (OGG) in some cases — no need to purchase a separate intra-island flight from Honolulu. 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.Airline: American, Delta, United, AlaskaRoutes: PHX/TUS/SAN/ABQ/SJC/AUS/ATL/DTW to HNL/OGGCost: $317+ round-trip in economy classDates: February-May and August-December, depending on the routeBooking Link: Orbitz, Expedia or directly with the airlinePay With: The Platinum Card from American Express (5x on airfare), Chase Sapphire Reserve, Citi Prestige (3x on airfare plus excellent trip delay insurance) or Chase Sapphire Preferred Card (2x on travel)Here are a few examples of what you can book:Phoenix (PHX) to Kahului (OGG) for $317 round-trip on American:Tuscon (TUS) to Kahului (OGG) for $334 round-trip on United:San Diego (SAN) to Kahului (OGG) for $334 round-trip on United:Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
