Island Hopping in Hawaii Just Got More Expensive

HONOLULU – If you’re planning to island hop in Hawaii this summer, check airfare before you lock in your itinerary.

Interisland flight prices have climbed sharply in late April 2026, with Hawaii News Now reporting one-way fares around $150 each way and some round-trip examples reaching more than $600.

Jerry Agrusa, a professor at the University of Hawaii’s School of Travel Industry Management, described regular interisland fares at these levels as something he had “never” seen before.

The increase is affecting visitors and residents alike, from families trying to attend events on another island to travelers planning multi-island vacations.

Here’s what’s driving the jump, what travelers are seeing right now, and how to decide whether island hopping still makes sense for your trip.

How Much Do Interisland Flights in Hawaii Cost Right Now?

The Hawaii News Now report shared real examples from travelers and spoke with a travel industry expert who described the spike as unusual in scale.

What Were Prices Like Before?

Before the sharp increase began in mid-to-late April 2026, travelers on Reddit’s r/HawaiianAirlines reported paying $80 to $185 round trip for common interisland routes.

One frequent flyer noted paying under $80 per leg as recently as April 13. Southwest regularly ran promotional fares as low as $39 on interisland routes.

What Travelers Are Reporting Right Now

These are user-reported examples from news interviews and online forums, not a full market average.

But they paint a clear picture of how far prices have moved:

Note: These examples combine Hawaii News Now reporting with anecdotal traveler reports from late April 2026, so actual fares will vary by airline, date, and booking window.

A high school surf coach quoted in the Hawaii News Now story found a round-trip fare from Honolulu to Kahului at $638 for a single traveler, for a flight that takes about 35 minutes.

Why Did Interisland Airfare Jump So Fast?

The main reason for interisland airfare rising is due to higher jet-fuel costs and limited seat availability.

Jet fuel prices had doubled to more than $220 per barrel since the conflict in Iran escalated.

Jet fuel requires more production than gasoline and that much of the supply runs through the Middle East, making aviation especially exposed to the disruption.

Professor Agrusa explained that two things happened at once: a shortage of available interisland flights and fuel surcharges being passed directly to passengers.

Baggage fees have also changed, though exact costs depend on the airline, fare type, residency, loyalty status, and when the ticket was booked.

Some Reddit users reported seeing similar pricing between Southwest and Hawaiian on certain interisland routes, but this should be treated as anecdotal.

The HNN report points mainly to fuel costs and limited flight availability rather than blaming one carrier.

Still, travelers may also be feeling the effects of a less aggressive fare-war environment than Hawaii has had in past years.

Experts quoted in the report cautioned that even if fuel prices stabilize, airfares will likely take longer to come back down than they did to go up. (*cough, cough: Alaska/Hawaiian merger)

What This Means for Your Hawaii Trip

Should You Still Plan to Island Hop?

Island hopping is still possible. It’s just significantly more expensive right now.

If you were budgeting $150 to $200 round trip per person for an interisland flight, you may need to double that estimate for summer 2026 travel.

If you’re on a tight budget, this might mean choosing one island and exploring it deeply instead of splitting time between two.

What If You Already Booked?

If you already have interisland flights booked at an earlier price, you’re likely in good shape.

Prices have risen since mid-April, so your locked-in fare is probably lower than what’s available now.

Avoid canceling and rebooking unless you compare the current fare first, because you will likely pay more.

What You Do NOT Need to Worry About

This is not being reported as a safety issue.

Interisland flights are still operating. However, travelers should check their exact route and schedule because availability and pricing can vary by airline, date, and departure time.

How to Save on Flights Between Hawaiian Islands

Even with elevated fares, there are practical steps that may reduce what you pay:

Book as early as possible. The HNN report noted that athletes who booked weeks in advance got normal prices. Families who waited paid three to four times more.

Early booking is the single biggest lever you have.

Compare Southwest and Hawaiian for each leg. One local family interviewed said they’re flying Southwest one direction and Hawaiian back based on timing and price.

Check both airlines for every leg of your trip.

Look at off-peak days and times. Travelers on Reddit reported that early morning and late evening flights were sometimes cheaper than midday options.

Flexibility with timing may save money.

Consider whether island hopping fits your trip length. If you only have five to seven days in Hawaii, spending all of that time on one island may give you a better experience than spending $500+ and a half-day on transit between islands.

Use miles if you have them. With cash fares this elevated, redeeming airline miles for interisland flights may offer better value than usual.

Traveler Takeaway

Interisland flight prices in Hawaii have climbed to levels that a University of Hawaii travel industry professor described as unprecedented.

The increase appears linked to higher jet fuel costs and tighter flight availability, and experts say relief will come slowly even if the geopolitical situation improves.

If you’re planning a multi-island trip, book your interisland flights now rather than waiting.

If you haven’t booked yet and the numbers don’t work for your budget, consider a single-island trip instead. Hawaii has more than enough to fill a week on any one island.
