Inter-Island Travel in Hawaii: Complete Guide to Island Hopping

So you’ve made it to Hawaii — congratulations! But here’s the thing: staying on just one island is like eating only the frosting on a cupcake. Sure, it’s good, but you’re missing out on the whole experience. Each of Hawaii’s main islands has its own personality, landscape, and vibe. Oahu brings the urban energy, Maui serves up luxury and adventure, the Big Island delivers raw volcanic power, and Kauai? Pure Garden of Eden vibes.

Whether you’re trying to figure out which island to call home or just want to maximize your vacation, inter-island travel is your ticket to experiencing the full spectrum of what Hawaii has to offer. And the good news? Island hopping is easier and more affordable than you might think.

Let’s break down everything you need to know about getting from island to island — airlines, costs, booking hacks, what to pack, and how to do it all without blowing your budget.

Overview of Island Hopping Options in Hawaii

Hawaii’s isolation in the middle of the Pacific means there aren’t a ton of options for inter-island travel, but the ones that exist are pretty solid. Your main choices are:

• Commercial airlines — Hawaiian Airlines, Southwest Airlines, and Mokulele Airlines operate frequent flights between the islands
• Private charters — For those with deeper pockets or specific needs
• Ferry service — Extremely limited (more on this later)
• Cruise ships — For the leisurely crowd who want to unpack once

Let’s be real: 95% of inter-island travelers fly commercial. It’s fast, relatively cheap, and flights run constantly throughout the day. A typical inter-island flight takes 30-50 minutes in the air, though you’ll want to budget about 2-3 hours total when you factor in check-in, security, boarding, and baggage claim.

The main airports you’ll use for island hopping:

• Oahu: Honolulu International Airport (HNL) — the main hub
• Maui: Kahului Airport (OGG) — the busiest, plus smaller airports in Kapalua (JHM) and Hana (HNM)
• Big Island: Kona International Airport (KOA) on the west side, Hilo International Airport (ITO) on the east
• Kauai: Lihue Airport (LIH)
• Molokai: Molokai Airport (MKK)
• Lanai: Lanai Airport (LNY)

Inter-Island Airlines: The Complete Comparison

Three major carriers dominate Hawaii’s inter-island market, each with their own strengths, quirks, and pricing strategies. Here’s what you need to know:

Hawaiian Airlines

The OG of Hawaiian aviation. Hawaiian Airlines has been flying inter-island since 1929, and they’ve got it down to a science. They operate the most flights with the most route options, so if flexibility is your priority, Hawaiian is hard to beat.

Pros:

• Most frequent flights (hundreds per day)
• Widest route network, including smaller airports like Molokai and Lanai
• Free checked bag on most inter-island flights (with HawaiianMiles membership)
• Complimentary juice, coffee, and snacks
• Generally reliable and on-time

Cons:

• Often more expensive than Southwest
• Older fleet on some routes
• Baggage fees apply if you’re not a frequent flier member

Southwest Airlines

The mainland favorite arrived in Hawaii in 2019 and shook up the market with lower prices and their famous customer-friendly policies. Southwest flies inter-island routes between the four major islands (Oahu, Maui, Big Island, Kauai).

Pros:

• Two free checked bags (yes, really)
• No change fees — flexibility is king
• Often the cheapest option, especially if you book early
• Rapid Rewards points are generous and easy to use
• Free same-day standby

Cons:

• Fewer daily flights than Hawaiian
• No service to Molokai or Lanai
• Tiered assigned seating (Standard, Preferred, Extra Legroom) launched January 2026 — premium seats cost more than basic fares
• No snacks or drinks on short inter-island flights

Mokulele Airlines

The boutique option. Mokulele operates smaller planes (think 9-passenger Cessna Caravans) to smaller airports and more remote destinations. If you want to get to Hana, Kapalua, Molokai, or Lanai, Mokulele might be your only option.

Pros:

• Access to smaller, scenic airports
• Great views (low altitude, small planes)
• Personalized service
• Sometimes the only option for certain routes

Cons:

• More expensive per mile
• Strict weight limits (including your body weight)
• Smaller planes can feel cramped
• More susceptible to weather delays

Airline Comparison Table

Booking Tips and Finding the Best Prices

Here’s where you can save some serious cash. Inter-island flights can range from dirt cheap ($39 each way during sales) to eye-watering ($200+ during peak times). Follow these strategies and you’ll consistently land on the cheaper end:

1. Book Early (But Not Too Early)

The sweet spot is usually 3-6 weeks in advance. Book too early and you might miss a sale; book too late and you’ll pay premium prices. Set up price alerts on Google Flights or directly with the airlines.

2. Fly on Off-Peak Days and Times

Tuesday, Wednesday, and Saturday flights are typically cheaper. Early morning and late evening flights also tend to be discounted. The 6:00 AM flight? Yeah, it’s cheap for a reason, but if you’re not a morning person, the savings might not be worth the pain.

3. Use Airline Miles and Points

Hawaiian Airlines and Southwest both have excellent frequent flier programs. Southwest’s Rapid Rewards points are especially valuable for inter-island travel — you can often snag flights for 5,000-7,000 points one-way, which is a steal.

4. Check Both Airlines Every Time

Don’t assume one is always cheaper. Southwest often wins on price, but Hawaiian runs sales too. Use a flight comparison tool or check both sites manually.

5. Sign Up for Fare Alerts

Both airlines send out email alerts when they run sales. Hawaiian occasionally does “Flash Sales” with flights as low as $39 one-way. Southwest’s “Low Fare Calendar” feature is gold for finding the cheapest days to fly.

6. Consider a Hawaii Resident Discount

If you’re actually living in Hawaii, both airlines offer resident discounts (typically 10-15% off). You’ll need to show proof of residency like a Hawaii driver’s license or state ID. Speaking of which, make sure you know how to get a Hawaii driver’s license or state ID if you’re making the move.

7. Book Directly with the Airline

Third-party booking sites (Expedia, Kayak, etc.) might seem convenient, but if anything goes wrong, you’ll be stuck in customer service hell bouncing between the airline and the booking site. Book direct for easier changes and better support.

8. Bundle If It Makes Sense

Sometimes booking a multi-island package through a travel site can save money, especially if you’re also booking hotels and rental cars. Do the math first — often you’ll save more by booking separately.

Ferry Options Between Hawaiian Islands

Here’s the bad news: there’s basically no regular ferry service between the major Hawaiian islands.

The Hawaii Superferry tried to launch in 2007, offering vehicle and passenger service between Oahu, Maui, and Kauai. It was a beautiful dream — imagine driving your car onto a ferry in Honolulu and off in Maui a few hours later. But environmental concerns, legal battles, and financial troubles killed the project by 2009.

Today, your only ferry option is the Expeditions Maui-Lanai Ferry, which runs between Maalaea Harbor (Maui) and Manele Harbor (Lanai). Since the August 2023 Lahaina wildfire destroyed the old Lahaina Harbor terminal, the ferry now departs from Maalaea rather than Lahaina. It’s about a 70-minute crossing, runs 3 round trips daily, and costs around $30 one-way for adults (Hawaii residents get a $5 kamaaina discount). It’s the cheapest way to visit Lanai, but that’s pretty much the extent of Hawaii’s inter-island ferry system.

Why no ferries? A few reasons:

• The channels between islands are ROUGH — we’re talking open ocean with serious waves
• Flights are so frequent and cheap that ferries can’t compete
• Environmental and legal hurdles make new ferry projects nearly impossible
• The distances are farther than you think (Oahu to Maui is about 100 miles across open ocean)

Bottom line: Don’t plan your inter-island travel around ferries. Stick with flying.

Popular Day Trip Routes and Itineraries

One of the best things about inter-island travel is how easy it is to do day trips. You can wake up in Waikiki, spend the afternoon hiking on Kauai, and be back for dinner in Honolulu. Here are the most popular day trip routes:

Honolulu (Oahu) to Maui

Why: Beach lovers and adventure seekers flock to Maui for world-class snorkeling, the Road to Hana, and Haleakalā National Park.

Sample itinerary:

• 6:00 AM flight from HNL to OGG (30 minutes)
• Pick up rental car
• Snorkel at Molokini Crater or Turtle Town
• Lunch in Paia or Kihei
• Explore upcountry Maui or a quick beach afternoon
• 7:00 PM flight back to Oahu

Pro tip: Book snorkeling tours in advance — they fill up fast. And unless you’re a serious early bird, skip trying to do Haleakalā sunrise and a full day trip. It’s too much.

Honolulu (Oahu) to Big Island (Kona or Hilo)

Why: Volcanoes, black sand beaches, coffee farms, and some of the most diverse landscapes in Hawaii.

Kona-side itinerary:

• Early morning flight to KOA
• Snorkel at Kealakekua Bay (Captain Cook Monument)
• Lunch in Kona town
• Coffee farm tour in the afternoon
• Watch the sunset at a beach before evening flight home

Hilo-side itinerary:

• Early flight to ITO
• Visit Hawaii Volcanoes National Park (2.5 hours round-trip drive)
• See Rainbow Falls and Akaka Falls
• Explore downtown Hilo
• Evening flight back

Pro tip: Hilo is rainier and lusher; Kona is sunnier and drier. Choose based on your vibe and what you want to do.

Honolulu (Oahu) to Kauai

Why: The Garden Isle is the most dramatic and photogenic island — think Jurassic Park (literally, it was filmed here).

Sample itinerary:

• 7:00 AM flight to LIH
• Drive to Waimea Canyon (the “Grand Canyon of the Pacific”)
• Lunch in Hanapepe or Waimea
• Beach time at Poipu or explore Hanalei on the North Shore
• 8:00 PM flight back

Pro tip: Kauai is compact but drives take longer than you think due to winding roads. Don’t over-schedule.

Maui to Big Island

Why: Skip Oahu entirely and hop between neighbor islands. Great for volcano viewing or stargazing at Mauna Kea.

Sample itinerary:

• Morning flight from OGG to KOA
• Visit Puʻuhonua o Hōnaunau National Historical Park
• Lunch in Kona
• Afternoon at the beach or coffee farm
• Evening flight back to Maui

Oahu to Lanai (Via Ferry + Flight)

Why: Lanai is the most exclusive and secluded island, with luxury resorts and quiet beaches.

Sample route: Fly to Maui, take the Expeditions Ferry to Lanai, explore, ferry back, fly home. Or just fly direct to Lanai on Mokulele or Hawaiian if available.

What to Pack for Inter-Island Day Trips

Packing light is key for day trips. You’re only going to be gone for 12-14 hours, and you don’t want to lug around a massive bag. Here’s the essentials list:

The Carry-On Essentials

• Reef-safe sunscreen — Hawaii banned non-reef-safe sunscreen, so make sure yours is compliant
• Reusable water bottle — Stay hydrated and skip overpriced airport water
• Light jacket or hoodie — Planes can be cold, and mountain areas can be chilly
• Swimsuit and quick-dry towel — You’re in Hawaii, you’re getting wet
• Snacks — Airport and tourist area food is expensive. Bring bars, trail mix, or fruit
• Hat and sunglasses — Sun is strong year-round
• Flip-flops and water shoes — Beaches, hikes, and rocky shores require versatile footwear
• Small backpack — Easier than a tote for active day trips
• Portable charger — Your phone’s going to be working overtime as a camera and GPS
• ID and credit cards — Obviously, but don’t forget!

Optional But Handy

• Snorkel gear — Rentals are pricey; bringing your own saves money if you’ve got room
• GoPro or waterproof phone case — For underwater shots
• Bug spray — Especially for jungle/rainforest hikes
• Rain jacket — Windward sides of islands can be rainy

What to Wear

Keep it casual and functional. What to wear in Oahu applies to the other islands too: light, breathable fabrics, layers, and comfortable shoes. Think aloha attire — relaxed, practical, and island-appropriate. Avoid heavy jeans, heels, or anything that screams “I’m uncomfortable.”

Renting Cars on Other Islands

Unless you’re staying at a resort and never leaving, you’ll want a rental car for inter-island day trips. Public transportation exists but is limited, and rideshares can be unreliable outside of Honolulu.

Booking Your Rental Car

• Book in advance — Hawaii’s car rental market is tight, especially during peak seasons. Book as soon as you book your flight.
• Pick up at the airport — It’s the most convenient option, and off-airport lots can involve long shuttle waits.
• Compare prices — Use sites like AutoSlash, Costco Travel, or AAA for discounts. Turo (peer-to-peer car rental) is also an option on some islands.
• Check insurance coverage — Your credit card or personal auto policy might already cover you, so don’t double-pay.
• Fuel policy matters — “Full to full” is usually cheapest (pick up with a full tank, return it full).

Driving Tips

• Respect local speed limits and driving culture — Locals drive slower and more cautiously. Don’t be that aggressive tourist.
• Let faster drivers pass — Use pullouts on narrow roads like the Road to Hana.
• Watch for pedestrians and cyclists — Especially in beach towns.
• Don’t leave valuables in the car — Break-ins at trailhead parking lots are unfortunately common.

Which Islands Need a Car?

• Big Island: Absolutely yes. It’s huge and spread out.
• Maui: Yes, unless you’re staying in one resort area.
• Kauai: Yes, public transit is minimal.
• Oahu: Maybe. Honolulu/Waikiki has good transit (TheBus), but North Shore and windward side require a car.
• Molokai/Lanai: Yes, though these islands are small and have limited options.

Inter-Island Shipping and Moving Between Islands

Planning to move from one island to another, or need to send stuff ahead before a trip? Hawaii has several shipping options, but they’re not cheap.

Shipping Your Belongings

If you’re relocating between islands, you’ll likely use one of these services:

• Young Brothers — The main inter-island cargo carrier. They ship everything from boxes to cars to furniture. Slow but reliable.
• Aloha Freight Forwarders — Another cargo option with regular barge service between islands.
• USPS — Surprisingly effective for smaller shipments. Flat-rate boxes can be a bargain.
• UPS/FedEx — Standard shipping services work inter-island, but expect higher rates than mainland shipping.

If you’re moving permanently between islands, check out our guide on how to ship to Hawaii — a lot of the same principles apply to inter-island moves.

Shipping Costs

Expect to pay a premium. A standard pallet via Young Brothers might run $150-$300 depending on size, weight, and route. Cars cost $500-$1,000+ to ship between islands. Compare the cost of shipping your car versus just selling it and buying another one on your destination island — sometimes the latter makes more sense.

What You Can’t Ship

Hawaii has strict agricultural rules to prevent invasive species. You can’t transport certain plants, soil, or animals between islands without permits. Check with the Hawaii Department of Agriculture before shipping anything questionable.

Budget Island Hopping Tips

Island hopping doesn’t have to drain your bank account. Here’s how to do it on a budget:

1. Skip the Hotels — Do Day Trips Instead

Hotels add up fast. If you’re based on Oahu, you can day-trip to Maui, Kauai, or the Big Island for less than the cost of a single night in a Maui resort. Wake up early, fly out, explore all day, fly back.

2. Bring Your Own Food

Restaurant prices in Hawaii are brutal — think $15-$20 for a basic lunch. Hit a grocery store before your flight and pack sandwiches, snacks, and fruit. Even grocery prices in Hawaii are high, but they’re still cheaper than eating out.

3. Use Free Activities

Beaches, hikes, waterfalls, scenic drives — Hawaii’s best attractions are free. Skip the $200 snorkeling tour and rent your own gear for $10.

4. Fly Southwest for Free Checked Bags

If you’re bringing snorkel gear, beach equipment, or gifts, Southwest’s two free checked bags policy is a game-changer. That alone can save $60-$120 per round trip compared to Hawaiian Airlines.

5. Rent Cars Through Discount Sites

Costco Travel, AAA, and AutoSlash often beat the prices on rental car company sites. Sometimes by a lot.

6. Travel Off-Peak

Late April to early June and September to mid-November are shoulder seasons — fewer crowds, cheaper flights, and better hotel deals.

7. Join Airline Loyalty Programs (Free)

Even if you don’t fly often, signing up for HawaiianMiles or Southwest Rapid Rewards is free and gets you access to sales, bonus point offers, and occasionally free checked bags.

8. Share a Rental Car

Traveling with friends or family? Split the cost of a rental car and gas. A $70/day rental becomes $17.50 per person when split four ways.

Frequently Asked Questions (FAQ)

How much does it cost to fly between Hawaiian islands?

Inter-island flights in Hawaii typically range from $49 to $200 one-way, depending on the airline, route, and how far in advance you book. Southwest Airlines often has the lowest fares (starting around $49-$79), while Hawaiian Airlines ranges from $69-$150 for most routes. Mokulele Airlines to smaller airports like Hana or Molokai can cost $89-$300. Booking 3-6 weeks in advance and flying on off-peak days (Tuesday, Wednesday, Saturday) will get you the best prices. Watch for flash sales where prices can drop to $39 one-way.

Is there a ferry between Hawaiian islands?

No, there is no regular ferry service between the major Hawaiian islands (Oahu, Maui, Big Island, Kauai). The only active inter-island ferry is the Expeditions Maui-Lanai Ferry, which runs between Maui (Maalaea Harbor) and Lanai (Manele Harbor). Since the 2023 Lahaina fire it departs from Maalaea rather than the old Lahaina Harbor. This roughly 70-minute ferry runs 3 round trips daily and costs about $30 one-way for adults. The Hawaii Superferry attempted inter-island service in 2007-2009 but shut down due to environmental concerns and legal issues. For travel between major islands, flying is your only practical option.

Can you do a day trip to another Hawaiian island?

Absolutely! Day trips between Hawaiian islands are easy and popular. With flights taking only 30-50 minutes and frequent departures throughout the day, you can easily fly from Oahu to Maui, Kauai, or the Big Island in the morning, spend 6-8 hours exploring, and return the same evening. Popular day trip itineraries include Oahu to Maui for snorkeling, Oahu to Kauai for Waimea Canyon, and Oahu to Big Island for volcano viewing. Book an early morning flight out (6-7 AM) and an evening return flight (7-9 PM) to maximize your time. Rent a car at the airport for flexibility.

Which airline is better for inter-island travel in Hawaii — Hawaiian or Southwest?

Both airlines have pros and cons. Southwest Airlines is typically cheaper ($49-$150 one-way), offers two free checked bags, has no change fees, and provides generous Rapid Rewards points. However, they have fewer daily flights and use open seating (no assigned seats). Hawaiian Airlines has more flights (150+ daily), serves smaller airports like Molokai and Lanai, offers assigned seating, and provides complimentary snacks and drinks. Prices range from $69-$200 one-way. Hawaiian also offers one free checked bag for HawaiianMiles members. Choose Southwest for budget and baggage, Hawaiian for frequency and route options.

Do I need a passport to fly between Hawaiian islands?

No, you do not need a passport for inter-island flights within Hawaii. Since all the Hawaiian islands are part of the United States, inter-island travel is considered domestic. You’ll need a valid government-issued photo ID (driver’s license, state ID, or passport) if you’re 18 or older. If you’re a Hawaii resident, make sure you have your Hawaii driver’s license or state ID handy, as some airlines offer resident discounts when you show proof of residency at check-in. Minors traveling without an adult may need additional documentation depending on the airline’s policy.

Final Thoughts: Island Hopping Is Worth It

If you’re spending any significant time in Hawaii and you stick to just one island, you’re cheating yourself. Each island has a completely different personality and landscape. Oahu’s got the city energy and world-class beaches. Maui brings the luxury and adventure. The Big Island is raw, volcanic, and massive. Kauai feels like you’ve stepped into a nature documentary. Molokai and Lanai offer seclusion and quiet.

The good news? Hopping between them is easier and cheaper than most people think. Flights are short, frequent, and affordable if you know when and how to book. Pack light, rent a car, bring your own snacks, and embrace the adventure.

So what are you waiting for? Book that inter-island flight, grab your reef-safe sunscreen, and go explore. The islands are calling.

Aloha and safe travels!

2026 Update: Inter-Island Routes, Pricing & Operational Changes

Inter-island travel has shifted in three meaningful ways since this guide was first published. Hawaiian Airlines completed its merger with Alaska Airlines in late 2024, and 2026 sees the integrated brand operating most inter-island routes under combined scheduling. Mokulele Airlines continues to expand into the underserved Lanai, Molokai, Kalaupapa, and Hana markets with Cessna Grand Caravan service. And the long-discussed inter-island ferry has not returned — the Hawaii Superferry remains shut down since 2009, with no public funding currently allocated to restart it.

Current Inter-Island Flight Pricing (2026)

Realistic round-trip pricing for the main inter-island corridors as of 2026, based on 2-week-advance booking on Hawaiian Airlines or Southwest Airlines:

• Honolulu (HNL) ↔ Kahului (OGG, Maui): $130–$220 round-trip; the busiest corridor with 30+ daily flights
• Honolulu (HNL) ↔ Kona (KOA, Big Island): $160–$260 round-trip; 15+ daily flights
• Honolulu (HNL) ↔ Hilo (ITO, Big Island): $160–$280 round-trip; 8–12 daily flights
• Honolulu (HNL) ↔ Lihue (LIH, Kauai): $140–$240 round-trip; 12–18 daily flights
• Kahului (OGG) ↔ Kona (KOA): $150–$260 round-trip; 4–6 daily flights
• Kahului (OGG) ↔ Lihue (LIH): $180–$300 round-trip; 2–4 daily flights

Same-day booking premiums are real. Last-minute fares on the Honolulu–Kahului corridor commonly hit $350–$500 round-trip; booking three weeks ahead typically holds at $150 or less. Southwest Airlines entered the Hawaii inter-island market in 2019 and remains a price-discipline force on the major corridors. The Hawaii Department of Transportation Airports Division publishes current airport-by-airport service rosters.

Mokulele Airlines: The Small-Plane Network

Mokulele Airlines (operating under Southern Airways Express since 2022) covers the routes the major carriers skip. Cessna Grand Caravan service with 9-seat capacity operates the following inter-island and intra-island routes in 2026:

• Honolulu ↔ Molokai (MKK): 3–4 daily; $120–$180 round-trip
• Honolulu ↔ Lanai (LNY): 2–3 daily; $140–$200 round-trip
• Kahului ↔ Molokai (MKK): 2 daily; $110–$170 round-trip
• Kahului ↔ Lanai (LNY): 2 daily; $110–$170 round-trip
• Kahului ↔ Hana (HNM): 1–2 daily; $130–$190 round-trip — alternative to the Road to Hana drive
• Kalaupapa (LUP): Molokai-only access to the historic settlement; National Park Service tour permits required

Mokulele’s small-plane experience differs materially from Hawaiian or Southwest. Weight-based seating, weather-driven cancellations, and a 35–55 pound checked-luggage cap are routine. Visibility is exceptional — most Mokulele flights operate below 10,000 ft.

Ferry Reality in 2026: There Isn’t One

The Hawaii Superferry, which briefly operated Oahu–Maui and Oahu–Kauai routes from 2007 to 2009, remains shut down. There is no public ferry serving any inter-island route in Hawaii as of 2026. Discussions about restoration surface periodically in the state legislature but no funding has been allocated.

Two limited shuttle services do operate:

• Expeditions Maui-Lanai Ferry: Maalaea Harbor (Maui) to Manele Harbor (Lanai); ~70 minutes; ~$30 one-way; 3 round trips daily. Relocated from Lahaina to Maalaea Harbor after the August 2023 Lahaina fire.
• Molokai Princess: Lahaina to Kaunakakai (Molokai); discontinued indefinitely since 2016. Not currently operating.

For all practical purposes, inter-island travel means flying. The full Hawaiian Airlines route map shows current Hawaii service.

TSA, Real-ID, and Inter-Island Security in 2026

All Hawaii inter-island flights are subject to TSA screening. The Real-ID requirement is now fully enforced: passengers age 18+ must present either a Real-ID-compliant driver license, passport, military ID, or other TSA-approved credential. The Hawaii driver license has been Real-ID-compliant since 2018 — the gold star in the upper right confirms compliance.

Pre-check is increasingly common on inter-island routes. Hawaii residents who routinely travel between islands report meaningful time savings; visitors holding Pre-Check enrollment can use it on Hawaii inter-island flights. The Transportation Security Administration publishes current acceptable IDs.

Cargo and Pets: What Flies With You

Inter-island flights carry less restrictive luggage rules than mainland-Hawaii flights but more restrictive than purely domestic flights. Key 2026 specifics:

• Hawaiian Airlines / Alaska Airlines: 1st checked bag $25 ($35 at airport); 50 lb / 62 linear inches
• Southwest Airlines: 2 checked bags free; 50 lb / 62 linear inches
• Mokulele Airlines: 1 checked bag $25; combined weight limits apply
• Pet in cabin: $125 each way on Hawaiian/Alaska; small dogs and cats only; advance booking required
• Surfboards and golf bags: standard checked-baggage rates apply on most carriers

The Hawaii Department of Agriculture’s agricultural inspection applies to all departing inter-island and mainland flights. Plant matter (fruits, vegetables, soil) must clear inspection before departure.

Pet Transport Between Hawaiian Islands

Once a pet has cleared the Hawaii rabies-quarantine inspection at first entry, inter-island pet transport is straightforward. No additional quarantine applies. Common inter-island pet logistics:

• Small dogs and cats in cabin: $125 each way; advance booking
• Larger dogs as cargo: $350–$650 each way depending on size and route; Hawaiian Airlines and Alaska Airlines accept
• Mokulele Airlines: small pets only; case-by-case approval; weight limits

Our moving to Hawaii with pets guide covers the initial state-entry quarantine; once cleared, inter-island travel is routine.

Best Time to Book Inter-Island Flights

Hawaii inter-island pricing follows distinct patterns:

• 2–4 weeks before travel: lowest fares; book here if dates are flexible
• Tuesday and Wednesday departures: typically 15–25% cheaper than Friday-Sunday
• Late-night (after 8 PM) and early-morning (before 7 AM): cheapest time slots
• Holiday windows (Thanksgiving, Christmas, spring break): book 8+ weeks ahead
• Same-day: avoid unless schedule demands it; premium typically $150+

Mokulele routes show less pricing variation than the major carriers. Hawaiian Airlines status holders should compare cash-fare prices against award-redemption value carefully — inter-island award pricing is often less attractive than cash.

Combining Islands: Practical Itineraries

For visitors with a week or more, multi-island itineraries are increasingly common. Realistic combinations:

• Oahu + Maui (7 days): 3 nights Oahu, 4 nights Maui; one short inter-island flight
• Oahu + Big Island (7 days): 3 nights Oahu, 4 nights Kona; one flight
• Maui + Big Island (8 days): 4 nights Maui, 4 nights Big Island; one flight
• Three islands (10–14 days): Oahu + Maui + Big Island OR Kauai; two flights
• Maui + Lanai day trip: ferry-based; no inter-island flight required
