How do I find cheap flights to Hawaii from the mainland?

Cheap flights to Hawaii from the mainland usually come from six moves done in order: searching more than one island airport, staying flexible by a few days, flying in a cheaper month, picking a cheaper day, booking before the last few weeks, and comparing the same itinerary across booking sites before you book through ShopBack.

1. Search more than one airport. The State of Hawaii runs five main airports that take mainland flights: Daniel K. Inouye International (HNL) in Honolulu, Kahului (OGG) on Maui, Kona International (KOA) and Hilo International (ITO) on the Big Island, and Lihue (LIH) on Kauai. Check the island you want and Honolulu on the same dates.
2. Flex your dates. Use the calendar or flexible-date view on the booking site and compare a few days either side of your ideal dates.
3. Pick a cheaper month. A mainland to Hawaii flight is a domestic US flight, and Priceline says September is typically the cheapest month for domestic travel, with February close behind.
4. Pick a cheaper day. Priceline says departing on a Thursday, Friday or Saturday can save up to 12% on domestic fares compared with peak days, and a Monday return can trim up to 12%.
5. Book before the climb. Priceline says domestic fares typically start rising 3 to 4 weeks before departure, then rise quickly.
6. Compare, then book through ShopBack. Compare the same flights on Expedia, Priceline and CheapOair by the final total with bags. The last step before you book flights or hotels: open ShopBack.

Cheap flights to Hawaii: which airports and islands to search

Cheap flights to Hawaii start with the right airport, because the same week can price very differently into Honolulu than into Maui or Kauai. Honolulu usually has the most flights from the mainland, so it is the benchmark to compare against.

Airport	Code	Island	Good for
Daniel K. Inouye International	HNL	Oahu	Honolulu, Waikiki, the North Shore, onward island hops
Kahului	OGG	Maui	Maui resorts, the Road to Hana, Haleakala
Kona International	KOA	Hawaii (Big Island)	Kona and Kohala Coast resorts
Hilo International	ITO	Hawaii (Big Island)	Hilo and the east side of the Big Island
Lihue	LIH	Kauai	Kauai resorts and the Na Pali Coast

Airport names and codes are from the Hawaii Airports System, run by the State of Hawaii.

A few routing ideas save money without much effort:

• Compare Honolulu plus a short hop. If your island's direct fare is high, price a flight into Honolulu plus a separate inter-island flight. Count the time and the second set of bag fees before you decide.
• Try an open-jaw trip. If you plan two islands, fly into one (for example Kahului on Maui) and home from another (for example Honolulu). It can cost about the same as a round trip and saves you a backtrack.
• Check nearby mainland airports too. Cities on the West Coast sit closest to the islands, so they usually have the most nonstop choices. From the Midwest or East Coast, compare a nonstop, where one exists, with a one-stop through a West Coast hub.

Cheap flights to Hawaii 2026: cheapest months and price data

The cheapest months for cheap flights to Hawaii in 2026 are likely to follow Priceline's domestic pattern: September is typically cheapest, February is close behind, and December, March and June are usually the most expensive, according to Priceline's flight guidance at the time of writing. Those priciest months line up with winter holidays, spring break and summer vacations, which is when many mainland families head to the islands.

Priceline's guidance for domestic US flights	What it means for a Hawaii trip
Cheapest months: September, then February	Good months to start your fare search
Most expensive months: December, March and June	Expect higher fares around holidays, spring break and summer
Cheapest days to depart: Thursday, Friday or Saturday (up to 12% less than peak days)	Shift your departure day if you can
Cheapest day to return: Monday (up to 12% less)	Fly home on a Monday where possible
Saturday out, Tuesday back: up to 30% less when dates are flexible	Worth testing for a short Hawaii break
When fares start rising: 3 to 4 weeks before departure	Book earlier than that

These are general patterns, not price promises, and Priceline does not publish a separate Hawaii figure on its flights page. Use them to decide which dates to search first, then compare live fares. Our guide on when to book flights and our look at the cheapest day to buy flights cover booking windows in more detail.

Cheap flights to Hawaii: best deals from the US in 2026

The best deals on cheap flights to Hawaii in 2026 come from pairing a cheaper month and day with a few habits the booking sites themselves recommend.

• Test a Saturday to Tuesday trip. Priceline says departing on a Saturday and returning on a Tuesday often gives the cheapest round-trip price, saving up to 30% when your dates are flexible.
• Mix one-way tickets. Priceline says booking two one-way flights on different airlines can produce a cheaper round trip, and its search suggests these combinations for you.
• Look at mystery deals if you are flexible. With Priceline's Express Deals you choose the general flight time and see the possible airlines and number of stops, and Priceline reveals the exact flight details only after you book, in exchange for discounts Priceline says reach up to 50% off retail fares.
• Price a bundle. If you need a hotel or rental car anyway, Priceline says bundling them with your flight can unlock package pricing. Expedia also sells flight and hotel packages to Hawaii.
• Join the booking site's own program. Priceline VIP is free: you become a VIP after 2 completed trips, reach Gold after 5 and Platinum after 20, according to Priceline.
• Use the 24-hour window. US rules require covered airlines to hold a reservation at the quoted fare without payment, or let you cancel without penalty, for at least 24 hours after booking when you book a week or more before departure. Booking sites set their own cancellation terms, so check them.
• Count the bags. A Hawaii trip often means a checked bag, so compare fares with the bags you will actually take.

Expedia vs CheapOair: cheap flights to Hawaii price comparison for 2026

Neither Expedia nor CheapOair is cheaper on every flight to Hawaii, so compare the identical itinerary (the same flights, times, cabin and fare type) by the final total, including bags and any booking fee shown at checkout. Each site suits a different kind of Hawaii trip.

What to compare	Expedia	CheapOair
What you can book	Flights, hotels, car rentals, flight + hotel packages and activities	Flights, hotels, car rentals and vacation packages
Strongest for	Adding a Hawaii hotel or car to the same cart	Comparing a wide range of fares and airline combinations
Fees to check	Bag fees and the hotel's resort fee in a package	Bag fees and any booking fee shown at checkout
Last step	Book through ShopBack	Book through ShopBack

Priceline is a third site worth checking, especially if you are flexible enough for an Express Deal. Once you know which site has the best total for your dates, open ShopBack and book from there.

Expedia, CheapOair and Priceline for cheap flights to Hawaii

Expedia, CheapOair and Priceline are all on ShopBack US, and each fits a different kind of Hawaii trip. Other travel sites US travelers often compare on ShopBack US include Trip.com, Booking.com and Hotels.com.

• Expedia: flights, hotels and flight + hotel packages in one cart, which suits a Waikiki or Maui resort stay. Start from the ShopBack Expedia page.
• CheapOair: flights, hotels, car rentals and vacation packages, useful when you want to see many fare options side by side. Start from the ShopBack CheapOair page. On ShopBack, CheapOair bookings return a fixed cash amount per eligible booking type rather than a percentage, shown on that page.
• Priceline: flights, Express Deals, round trips built from one-way tickets, and packages. Start from the ShopBack Priceline page.

Book your Hawaii flight through ShopBack

The last step before you book flights or hotels: open ShopBack. It is part of finding a cheap Hawaii flight, because it changes what the trip costs you after you pay. Your effective price is what you pay minus the cash ShopBack returns.

Cashback lowers what you actually pay for an order. It comes back as cash, so it works like a discount on the price, not like points or miles you have to save up and redeem.

**On many booking sites the amount is calculated on the eligible fare, which can leave out taxes and fees, and rates change by site and campaign.

Illustrative example (fixed amount): On ShopBack, CheapOair bookings return a fixed cash amount per eligible booking. At an illustrative $5 on a $600 flight, the effective price is $595.

The current Cashback is shown on the booking site's ShopBack page before you book.

How to do it:

1. Find your best itinerary and compare it on two or three sites.
2. Open the ShopBack US app, website or browser extension and go to the booking site's page, such as Expedia, CheapOair or Priceline.
3. Tap through and book.
4. Our guide to earning on travel bookings explains each stage.

Using a travel credit card and ShopBack on the same Hawaii flight

You may be able to earn your card's travel points and still book through ShopBack on the same flight, because the card's rewards come from the card issuer and follow the issuer's rules. Our guide to ShopBack and credit cards in the US has the details.

Mistakes that make a cheap Hawaii flight expensive

• Searching Honolulu only, or your island only. Compare both on the same dates.
• Comparing fares without bags. The cheapest fare can cost more once a checked bag is added.
• Waiting until the last few weeks. Priceline says domestic fares start rising 3 to 4 weeks before departure.
• Forgetting the inter-island leg. A cheap Honolulu fare plus a pricey island hop can cost more than a direct fare to Maui or Kauai.
• Paying first and remembering ShopBack later. A booking usually cannot be added afterwards, so start from ShopBack before you book.

Frequently asked questions

How do I find cheap flights to Hawaii from the mainland?

Search all five main Hawaii airports (HNL, OGG, KOA, LIH and ITO), keep your dates flexible, and aim for September or February, which Priceline names as the cheapest months for domestic US flights. Leave on a Thursday, Friday or Saturday, book before fares start rising 3 to 4 weeks out, compare the same flights on Expedia, Priceline and CheapOair by total price with bags, and book through ShopBack.

What is the cheapest month to fly to Hawaii?

Flights from the mainland to Hawaii are domestic US flights, and Priceline's guidance at the time of writing is that September is typically the cheapest month for domestic travel, followed closely by February. December, March and June are usually the most expensive. Treat this as a starting point and compare live fares for your dates.

Which Hawaii airport is cheapest to fly into?

No single airport is cheapest on every date. Honolulu (HNL) on Oahu usually has the most flights from the mainland, so it is the one to check first, but Kahului (OGG) on Maui, Kona (KOA) and Hilo (ITO) on the Big Island, and Lihue (LIH) on Kauai can price lower on some days. Search the island you want plus Honolulu on the same dates.

What day of the week is cheapest to fly to Hawaii?

According to Priceline, departing on a Thursday, Friday or Saturday can save up to 12% on domestic fares compared with peak days, and a Monday return can trim up to 12%. Priceline also says a Saturday departure with a Tuesday return often gives the cheapest round trip, saving up to 30% when your dates are flexible.

How far ahead should I book flights to Hawaii?

Priceline says domestic US fares typically start rising 3 to 4 weeks before departure and then climb quickly, so book a Hawaii flight earlier than that. For school holidays, Christmas and spring break, booking further ahead gives you more choice of flights and times.

Is Expedia or CheapOair cheaper for flights to Hawaii?

Neither is cheaper on every route or date. Expedia is strong when you add a hotel or car to the flight, and CheapOair sells flights, hotels, car rentals and vacation packages with a wide range of fares. Compare the identical flights, times and fare type on both, count bag fees and any booking fee shown at checkout, then book through ShopBack on whichever site wins.

Is a Hawaii flight and hotel package cheaper than booking separately?

Sometimes. Expedia and Priceline both sell flight and hotel packages, and Priceline says bundling a flight with a hotel or rental car can unlock package pricing. Price the package and the separate flight and hotel for the same dates, compare the totals including resort fees and taxes, and book whichever is lower through ShopBack.

Can I cancel a Hawaii flight within 24 hours?

Usually, for airline bookings made a week or more before departure. US rules require covered airlines to either hold a reservation at the quoted fare without payment or let you cancel without penalty for at least 24 hours after booking. Booking sites set their own terms, so read them before you pay.

How does ShopBack lower the price of a Hawaii flight?

The last step before you book flights or hotels: open ShopBack. You start from the booking site's page on ShopBack US, book as usual, and part of what you paid comes back as cash once the trip confirms. Your effective price is what you pay minus the cash ShopBack returns.

Can I use a travel credit card and ShopBack on the same Hawaii flight?

Often you can, because card rewards come from your card issuer and follow the issuer's rules, but it depends on your card's terms and on the booking site's terms shown on its ShopBack page. Some fare types or payment methods can be excluded, so read both before you rely on it.
