What to expect when you rent a car at HNL
Honolulu International Airport (HNL) has six car rental companies operating from the same facility on the airport grounds, about a ten-minute walk or free shuttle ride from the terminal. You can reserve a car before you arrive, pick it up after you clear baggage claim, and drive off the same day. The rental counter is in the ground-floor baggage claim area, and the parking lot is adjacent — no separate shuttle to an off-site lot.
The major companies at HNL are Enterprise, Hertz, Budget, Avis, National, and Alamo. All operate from the same building, so you can compare prices and walk between counters if you want. Rates vary by company, car type, and season; Hawaii's peak travel months (December, July, August) tend to have higher daily rates than shoulder seasons.
You will need a valid driver's license, a credit card in your name, and proof of insurance (either your own policy or the rental company's coverage). If you are under 25, most companies charge an additional daily fee — typically $15 to $25 per day, depending on the company. Some companies require you to be at least 21; a few set the minimum at 25.
Key Takeaways
- All six rental companies at HNL operate from one ground-floor facility in the baggage claim area, so you can compare rates before committing to a reservation.
- Bring your driver's license, a credit card in your name, and proof of insurance — either your own policy or the rental company's damage waiver.
- Drivers under 25 pay an extra daily fee (usually $15 to $25), and some companies require you to be at least 21 or 25 to rent.
- Reserve ahead during peak months (December, July, August) because rates rise and inventory tightens, but you can often walk in and rent same-day during slower periods.
- Return the car with a full tank of gas; most companies charge a refueling fee if you return it empty, and Hawaii gas prices are higher than the mainland.
Reserving a car before you arrive
Booking online before your trip locks in a rate and guarantees a car type (or a car in that class). Most companies offer discounts for advance reservations, especially if you book directly through their website rather than through a third-party booking site. You can reserve as far in advance as you want, and you can usually cancel or modify the reservation free of charge up to 24 hours before pickup.
When you reserve, you will choose a car class (economy, midsize, SUV, etc.) rather than a specific model. The rental company assigns the actual car when you arrive. If the class you reserved is unavailable, the company will offer you an upgrade at no extra charge — a common practice at HNL because demand fluctuates.
Third-party booking sites (Kayak, Expedia, Autoslash, Turo) often show lower advertised rates than the rental company's own website, but read the fine print: some include insurance or charge extra fees that the company's direct booking does not. Compare the total cost, not just the daily rate.
What to bring and what to expect at pickup
Have your driver's license, credit card, and proof of insurance ready when you reach the counter. If you are using your own car insurance, bring the policy or a declaration page showing your coverage limits and that rental cars are covered. If you do not have rental coverage and do not want to buy the company's damage waiver, tell the agent before they run your credit card — some companies will not rent without one or the other.
The agent will ask whether you want the rental company's damage waiver (called a Loss Damage Waiver, or LDW). This typically costs $15 to $30 per day and covers collision and theft damage. If you decline it, you are liable for any damage to the car. Your personal auto insurance may cover rental cars, but check your policy first — not all do, and coverage limits vary.
The agent will also offer fuel options. The standard option is to return the car with a full tank; if you return it empty or partially full, the company charges a refueling fee (usually $5 to $8 per gallon, which is much higher than gas station prices). Some companies offer a prepaid fuel option where you pay for a full tank upfront at a lower per-gallon rate; this makes sense only if you plan to return the car nearly empty.
The pickup process usually takes 10 to 15 minutes. The agent will walk you through the rental agreement, show you the car's condition, and point out any existing damage on a checklist. Take photos of the car's exterior and interior before you drive away — this protects you if the company later claims you caused damage you did not.
Driving in Hawaii and returning the car
Hawaii has the same traffic laws as the mainland: drive on the right, obey speed limits (typically 25 to 55 mph depending on the road), and wear a seatbelt. Honolulu traffic is heaviest during rush hours (7 to 9 a.m. and 4 to 6 p.m.). Parking is available throughout the island, but downtown Honolulu and Waikiki have paid lots and street meters. Many beaches and hiking trailheads have free parking.
Gas stations are scattered across Oahu, but prices are significantly higher than the mainland — expect to pay $4 to $5 per gallon depending on the station and current oil prices. Fill up before you return the car to avoid the rental company's refueling charges.
Return the car to the same HNL facility where you picked it up. The rental lot is clearly marked from the airport exit. Return it during business hours (usually 5 a.m. to midnight, though hours vary by company) so an agent can inspect it and process your return. If you return it after hours, you can leave it in the designated lot, but the company will inspect it the next day and may charge you for damage you did not cause if no agent was present to document the car's condition.
Bring the keys, the rental agreement, and your credit card. The agent will inspect the car for damage, check the fuel level, and process your return. The whole process takes 5 to 10 minutes. You will receive a receipt; keep it in case questions arise later about charges.
Insurance and damage coverage options
You have three ways to cover damage to the rental car: your own auto insurance, the rental company's damage waiver, or neither (in which case you pay out of pocket). Most people use one of the first two.
Your personal auto insurance may cover rental cars, but coverage varies widely. Some policies cover rentals only in the United States; others exclude rentals entirely. Some cover collision but not theft. Call your insurance company before you rent and ask specifically whether your policy covers rental cars in Hawaii and what your deductible is. If your coverage is limited or nonexistent, the rental company's damage waiver is worth buying.
The rental company's Loss Damage Waiver (LDW) typically costs $15 to $30 per day and covers collision, theft, and vandalism. It does not cover damage from driving under the influence, reckless driving, or off-road use. If you buy the LDW, you are not liable for damage to the car (except in those excluded cases). Some credit cards offer rental car coverage if you charge the entire rental to that card; check your card's benefits before you rent.
If you decline both your insurance and the company's waiver, you are liable for the full cost of repairs or replacement. A minor fender-bender can cost $500 to $2,000 in repairs; a total loss can cost $20,000 or more. This is a significant financial risk.
Age requirements and additional driver fees
Most companies at HNL require you to be at least 21 years old to rent. Enterprise and Budget sometimes rent to drivers as young as 18 or 19, but they charge a daily surcharge of $25 to $50 for drivers under 25. Hertz, Avis, National, and Alamo typically require you to be at least 25, with no exceptions.
If you are under 25 and want to rent, call the company directly before you book — policies change, and a phone conversation is faster than discovering the age restriction at the counter. Budget and Enterprise are your best options if you are under 21.
Additional drivers (anyone else who will drive the car) must be listed on the rental agreement. Most companies charge $10 to $15 per additional driver per day, though some waive the fee for spouses. All drivers must present a valid driver's license at pickup.
Frequently Asked Questions
Can I rent a car at HNL if I have an international driver's license?
Yes, but you must also have a valid passport. Most companies accept an International Driving Permit (IDP) along with your passport as proof of identity and driving authority. Bring both documents to the counter. Some companies may ask for an IDP even if your home country's license is in English; it is safer to have one.
What happens if I return the car late?
Most companies charge an hourly late fee (typically $15 to $30 per hour) if you return the car after your reservation time. Some charge a full day's rate if you are more than a few hours late. Check your rental agreement for the exact policy. If you know you will be late, call the rental company as soon as possible — they may extend your reservation without penalty if they have availability.
Can I take the rental car to the other Hawaiian islands?
No. Rental cars from HNL cannot leave Oahu. If you want to rent a car on another island (Maui, Big Island, Kauai), you must rent it at that island's airport. You can fly between islands and rent a separate car at each destination.
Do I need to buy a parking permit for Honolulu?
No. Street parking in Honolulu is metered or free depending on the location and time of day. Waikiki has paid parking lots. Most beaches and hiking areas have free parking. Check signage before you park — parking enforcement is active, and tickets are expensive.
What if the rental company charges me for damage I did not cause?
Request an itemized receipt showing the damage and the repair cost. If you took photos at pickup, compare them to the damage claim. If the damage was not visible in your photos, dispute the charge with your credit card company or insurance company. Keep all documentation — the rental agreement, photos, receipts, and any correspondence with the rental company.
