The best deals are from Portland (PDX) and Seattle on the West Coast, from $378-395 round-trip, but $523 (Philadelphia) to $599 (Boston) is a great deal from the East Coast, too. You can also find flights for a bit more from a few other cities, including San Diego and Salt Lake City, and you can fly to other destinations in Hawaii from the East Coast if you’re willing to spend more or add an additional stop in each direction.Airline(s): DeltaRoute(s): BOS, PDX, PHL, SEA to HNLCost: $378-$599 round-trip in economyDates: August 2015 through November 2015Elite Mileage Earning: At least 5,354 elite-qualifying milesFare Class: VBooking Link: OrbitzPay With: American Express® Gold Card, Citi Prestige or Chase Sapphire PreferredHere are a few examples of what you can book:Seattle to Honolulu for $378 on Delta (earns 5,354 MQMs):Seattle to Honolulu for $378 on Delta.Portland to Honolulu for $395 on Delta (earns 6,354 MQMs):Portland to Honolulu for $395 on Delta.Philadelphia to Honolulu for $523 on Delta (earns 10,334 MQMs):Philadelphia to Honolulu for $523 on Delta.Boston to Honolulu for $599 on Delta (earns 10,334 MQMs):Sign up for our daily newsletterEmail addressSign upI would like to subscribe to The Points Guy newsletters and special email promotions.
