Southwest flies LAX to Honolulu for $199–299 round trip with 2 free checked bags — that’s your surfboard sorted. But here’s what most “cheap flights to Hawaii” guides skip: which island you fly into changes the total trip cost by $300+ because inter-island flights add $80–150 each way, some islands have dramatically more expensive hotels, and most require a rental car. We compared six airlines to four islands from LA, San Francisco, and Seattle — and the cheapest flight isn’t always the cheapest trip.

Which Island Should You Fly Into? (This Matters More Than the Airline)
Every “cheap Hawaii flights” article compares airlines. Almost none compare islands — and that’s where the real money is. A $199 flight to Oahu versus a $249 flight to Maui looks like a $50 difference, but Maui needs a rental car ($60–120/day), more expensive hotels, and pricier restaurants. Here’s the honest breakdown:
🌊 Oahu (Honolulu — HNL)
Flights
Most options, cheapest fares ($199–350 RT)
Hotels
$120–400/night (widest range)
Rental Car
Optional — Waikiki is walkable, TheBus covers the island
Best For
First-timers, families, budget trips, nightlife
Oahu is a city with a beach, not a beach with a city. Waikiki has every hotel chain from $120 hostels to $800 luxury resorts. Pearl Harbor (free, reserve timed tickets online), Diamond Head crater hike ($5 entry, 1.5-mile round trip), North Shore surf beaches (30 min drive, legendary in winter). The trade-off: traffic, crowds, and a more urban vibe than the other islands. We think Oahu is the right call for first-timers and anyone on a budget — it has the cheapest flights, the most hotel competition, and you can skip the rental car if you stay in Waikiki.
🌴 Maui (Kahului — OGG)
Flights
Good options, $30–80 more than Oahu ($249–400 RT)
Hotels
$180–600/night (less budget options)
Rental Car
Essential — limited public transit
Best For
Couples, honeymooners, road trippers, snorkelers
Maui is most people’s idea of Hawaii. Road to Hana (64 miles of winding coast road, 620 curves, 59 bridges — best as an overnight trip), Haleakālā sunrise ($1 reservation + $30 park entry, arrive by 5:30am, genuinely life-changing), Wailea beaches (south shore, calmer water, resort area), whale watching (December–April, humpback whales breed offshore, boat tours $40–80). You need a rental car. Maui’s bus system is sparse, and everything worth seeing requires driving. Budget $50–120/day for a rental during peak season — and book early. Maui’s rental car shortage in 2021–2023 drove prices to $300/day; it’s better now but still spikes in summer and December.
🌋 Big Island (Kona — KOA / Hilo — ITO)
Flights
Fewer nonstops, some connect via HNL ($250–450 RT)
Hotels
$100–350/night (more affordable than Maui)
Rental Car
Essential — the island is massive
Best For
Adventure, volcanoes, nature lovers, repeat visitors
The Big Island is bigger than all other Hawaiian islands combined and has 10 of the world’s 14 climate zones. Hawaiʻi Volcanoes National Park ($30 per vehicle, Kīlauea crater, lava tube walks), Mauna Kea stargazing (13,796 feet, free visitor center at 9,200 feet with telescopes), black sand beaches at Punaluʻu (sea turtles bask here), Kona coffee farms (free tours and tastings along the Kona Coffee Belt). Kona (west side) is dry and sunny with resorts; Hilo (east side) is rainier and cheaper with a small-town feel. A rental car is non-negotiable — driving from Kona to Volcanoes National Park takes 2.5 hours one way.
🌳 Kauai (Lihue — LIH)
Flights
Fewest nonstops, LAX/SFO/SEA only ($280–500 RT)
Hotels
$200–600/night (most expensive island)
Rental Car
Essential — no public transit to speak of
Best For
Hikers, couples seeking quiet, experienced Hawaii travelers
Kauai is the oldest main island and the most lush — it feels like Jurassic Park because it literally was (filmed here in 1993 and several sequels). Nā Pali Coast (accessible by boat, helicopter, or the challenging 22-mile Kalalau Trail), Waimea Canyon (10 miles long, 3,600 feet deep — Mark Twain called it the “Grand Canyon of the Pacific”), Poipu Beach (south shore, calmest water, monk seals rest here). Kauai has the fewest direct mainland flights and the most expensive accommodations. It’s not the right first-trip island — but it’s arguably the most beautiful.
What Every Airline Costs to Hawaii
Six airlines compete on West Coast–Hawaii routes. The headline fare differences are small — but bag fees, route coverage, and perks vary wildly. We checked fares across all carriers in late March 2026.
| Airline | RT Fare Range | Departs From | Islands Served | Key Perk |
|---|---|---|---|---|
| Southwest | $199–350 | LAX, OAK, SAN, PHX | HNL, OGG, KOA, LIH | 2 free checked bags, no change fees |
| Alaska | $220–380 | SEA, PDX, LAX, SFO | HNL, OGG, KOA, LIH | Mileage Plan, frequent sales |
| Hawaiian | $250–450 | LAX, SFO, SEA, OAK, PDX, SAN, PHX | All islands + inter-island | Most frequencies, Extra Comfort seats |
| Delta | $280–500 | LAX, SEA | HNL, OGG | SkyMiles, Delta One on select routes |
| United | $280–500 | SFO, LAX | HNL, OGG, KOA | Star Alliance, Polaris on select |
| American | $280–500 | LAX | HNL, OGG | Oneworld miles, fewest options |
Fares checked via Google Flights + airline sites, late March 2026. Round-trip economy prices from various West Coast cities. Prices fluctuate daily.
The bag math that changes everything
Southwest’s 2 free checked bags per person is the single biggest differentiator on this route. Hawaiian Airlines charges $35 for the first bag, $45 for the second. Alaska charges $35/$45. United and American charge $40/$45. For a family of 4 with 2 bags each, that’s $280–560 in bag fees on non-Southwest airlines. Even if Southwest’s base fare is $30 higher, the bag savings more than cover it. For Hawaii specifically — where you’re packing snorkel gear, beach stuff, and potentially a surfboard — those free bags matter more than on any other route.

When to Fly — and When Hawaii Costs Double
| Period | Typical RT Fare | Notes |
|---|---|---|
| Mid-Jan to mid-Mar | $199–300 | Post-holiday lull. Still warm (75–80°F). Whale watching season on Maui. |
| September–November | $199–320 | Cheapest window. Slightly rainier but fewer crowds. Water is warmest (80°F). |
| April–May | $250–400 | Shoulder season. Great weather, moderate prices, Maui whale season ending. |
| June–August | $350–550 | Peak summer. Families flood in. Book 3–4 months ahead. |
| March (spring break) | $350–500 | College students + families. Prices spike for 2–3 weeks. |
| Thanksgiving week | $400–600 | Short spike. Book early or fly the Tuesday after. |
| Dec 15–Jan 5 | $450–700 | Peak peak. Holiday + winter escape demand. Hotels spike harder than flights. |
How to catch the $199 fare
Southwest releases Hawaii fares in batches — follow @SouthwestAir on X and set Google Flights price alerts for LAX/OAK/SAN–HNL. Alaska Airlines runs 2–3 Hawaii sales per year (usually January and August) with fares in the $220–260 range. Book 2–3 months out for the best economy prices. Tuesday and Wednesday departures save $30–60 versus Friday or Sunday. One more: if you’re flexible on which island, set alerts for all four — Kona and Lihue occasionally drop below Honolulu prices during off-peak.

Rental Cars — You Probably Need One (Except on Oahu)
On Oahu, you can skip a rental car if you’re staying in Waikiki. TheBus covers the island ($3 per ride, all-day pass $7.50), Uber and Lyft work everywhere, and most attractions are accessible by transit. For the North Shore, a car helps but the #52 bus gets there in about 90 minutes from Waikiki.
On Maui, Big Island, and Kauai — a rental car is non-negotiable. Public transit is minimal to nonexistent, Uber availability is hit-or-miss outside main towns, and everything worth seeing requires driving. Budget $50–120/day depending on season and vehicle type. Book as early as possible for peak seasons — Hawaii’s rental car supply still hasn’t fully recovered from the pandemic-era shortages, and summer/holiday prices spike to $100–180/day.
Rental car pro tip
Skip the rental insurance. Most US auto insurance policies and many credit cards (Chase Sapphire, Amex Platinum) cover rental car damage in Hawaii. Call your insurer and check your card benefits before you fly. The rental counter upsell for $20–35/day is usually unnecessary. Also: gas in Hawaii averages $4.90–5.50/gallon (March 2026, per AAA) — about $1 more than mainland West Coast prices.

Water Activities & Tours — The Whole Point of Hawaii
Hawaii is the boat trip capital of America. Snorkeling tours ($40–80 per person — Molokini Crater off Maui is the big one), sunset cruises ($60–120), whale watching (December–April on Maui, $40–80, humpback whales breach close enough to hear), Nā Pali Coast boat tours on Kauai ($150–250, the only way most people see these sea cliffs), deep-sea fishing off Kona ($200–600 half-day charter). Book popular tours 1–2 weeks ahead in peak season — the good boats sell out.
Travel Insurance — Yes, Even for a “Domestic” Trip
Hawaii is technically domestic, but you’re 2,500 miles from the nearest mainland hospital with your specialist. An emergency medical evacuation from Hawaii to the West Coast costs $25,000–50,000. Your health insurance covers you (it’s still the US), but medical transport off-island is usually excluded. If you’re doing anything active — snorkeling, surfing, hiking volcanic trails, zip-lining — a trip insurance policy at $30–60 for the week also covers flight cancellations, baggage delays, and the $800+ you’d lose on non-refundable hotel bookings.

Everything Costs More
Groceries in Hawaii run 20–40% above mainland prices — a gallon of milk is $7–8, a dozen eggs $5–7. Restaurant meals average $15–25 for lunch, $25–50 for dinner. Budget $80–120/day per person for food. The cheapest move: hit Costco or Foodland near the airport when you land (every island has at least one) and stock your Airbnb or hotel fridge with breakfast and snack supplies.
Reef-Safe Sunscreen Is Required by Law
Since 2021, Hawaii has banned sunscreens containing oxybenzone and octinoxate — these chemicals damage coral reefs. Reef-safe sunscreen is available everywhere on the islands but costs $15–25. Buy it on the mainland before you fly ($8–12 on Amazon or at Target). Brands: Sun Bum, Raw Elements, and Blue Lizard all make reef-safe versions.
Respect the Land
Don’t stack rocks — they’re cultural markers (ahu) with spiritual significance. Stay on marked trails. Don’t touch or approach sea turtles (honu) or Hawaiian monk seals — both are federally protected under the Endangered Species Act, and approaching within 10 feet is a federal offense with fines up to $50,000. These animals rest on beaches; give them space and enjoy from a distance. Take nothing from the beach — not even lava rocks (local belief holds it brings bad luck, and it’s also illegal from national parks).
Time Zone
Hawaii is HST year-round — no daylight saving time. That means it’s 2 hours behind the West Coast in summer (when the mainland is on PDT) and 3 hours behind in winter (when the mainland is on PST). If you fly out of LAX at 8am, you arrive in Honolulu around 11am Hawaii time. Jet lag is minimal — it’s like flying to a slightly different time zone, not crossing an ocean.
Emergency: Dial 911
Hawaii is a US state — 911 works for police, fire, and ambulance. For ocean emergencies (drowning, boat distress), the US Coast Guard Sector Honolulu responds at (808) 842-2600. Hawaii’s beaches have strong currents — swim only at lifeguarded beaches and check surf conditions at hawaiibeachsafety.com before heading out.
Frequently Asked Questions
What’s the cheapest airline to fly to Hawaii?
Southwest has the lowest all-in fares when you factor in bags. Base fares start at $199 round trip from LAX/OAK/SAN, and the 2 free checked bags save $70–140 per person versus Hawaiian, Alaska, or the legacy carriers. Alaska Airlines is the runner-up, with frequent sales dropping to $220–260. Hawaiian Airlines has the most routes but base fares run $30–80 higher than Southwest. Remember: Southwest doesn’t appear on Google Flights or Kayak — search southwest.com directly.
Which Hawaiian island is best for first-timers?
Oahu. It has the cheapest flights, the widest range of hotels (from $120 hostels to $800 resorts), and you don’t need a rental car if you stay in Waikiki. Pearl Harbor, Diamond Head, the North Shore, and Waikiki Beach are all on one island. The trade-off is it’s more urban and crowded than the other islands. If you’ve done Oahu and want the “postcard Hawaii” experience, Maui is the natural next step.
Do I need a rental car in Hawaii?
On Oahu: not if you stay in Waikiki. TheBus, Uber, and walking cover most attractions. On Maui, Big Island, and Kauai: yes, absolutely. Public transit is minimal, Uber is unreliable outside main towns, and every worthwhile beach, trailhead, and viewpoint requires driving. Budget $50–120/day and book early for peak season — Hawaii rental cars still spike to $100–180/day during summer and holidays.
When is the cheapest time to fly to Hawaii?
Mid-January through mid-March (post-holiday lull, whale watching season, still warm at 75–80°F) and September through November (slightly rainier, warmest water, fewest crowds). Avoid June–August, spring break in March, Thanksgiving week, and December 15–January 5. Book 2–3 months ahead. Southwest releases Hawaii fare batches periodically — set Google Flights alerts.
Is travel insurance worth it for Hawaii?
Yes, if you’re doing water sports or have non-refundable hotel bookings. Your regular health insurance works in Hawaii (it’s a US state), but medical evacuation to the mainland costs $25,000–50,000 and is usually excluded from standard plans. A week of trip insurance costs $30–60 and also covers flight cancellations and baggage delays — cheap peace of mind when you’re 2,500 miles from home.
