Hawaiian, Alaska Airlines, and JetBlue have round-trip flights from New York (JFK) to Kahului (OGG) for $354-$359 with a connection. Flights January, February, April, and May. Weekends available.
Some small OTAs on Skyscanner have this for as low as $337; which is cheaper than the airline. If you plan on booking there, beware of any site that charges a fee to cancel a ticket within the 24-hour “free” period. Use unknown booking sites at your own risk.
JetBlue’s “Basic” fares allow for a carry-on bag and a small personal item (17 x 13 x 8 inches), like a Jansport SuperBreak backpack without a fee. You can avoid seat selection fees by accepting the randomly assigned seat at the gate.
