What to expect when you rent a car at HNL
Honolulu International Airport (HNL) has six rental car companies operating from the same facility on the airport grounds, about a 10-minute walk or free shuttle ride from the terminal. You can pick up a car when ready after landing or reserve one in advance. The rental desks are located in the baggage claim area, and most companies offer vehicles ranging from economy cars to SUVs. Prices vary by company, season, and how far in advance you book — rates are typically higher during winter months (December through March) and lower in the shoulder seasons.
The process itself is straightforward: show your driver's license, provide a credit card for the deposit, sign the rental agreement, and collect your keys. Most rentals include basic liability coverage, though your personal auto insurance or credit card may cover additional protection. You'll need to return the car with a full fuel tank, or you'll pay the rental company's fuel surcharge, which is almost always more expensive than filling up yourself at a gas station near the airport.
Key Takeaways
- Six rental companies operate from HNL's central facility: Hertz, Avis, Budget, Enterprise, National, and Alamo, all within walking distance of baggage claim.
- You must be at least 21 years old with a valid driver's license and a credit card; some companies charge extra fees for drivers under 25.
- Reserve your car before you travel to lock in a rate, since walk-up prices at the airport are often significantly higher.
- Return the car with a full fuel tank to avoid expensive fuel surcharges; gas stations near HNL are located on Nimitz Highway, about 5 to 10 minutes from the rental facility.
- Check whether your personal auto insurance or credit card covers rental car damage before purchasing the rental company's collision coverage.
Which rental companies operate at HNL and what they offer
Hertz, Avis, Budget, Enterprise, National, and Alamo all have desks at Honolulu International Airport. All six are located in the same rental car facility, so you can compare prices and vehicle availability in person if you haven't booked ahead. Each company maintains a fleet of economy sedans, mid-size cars, SUVs, and minivans. Availability depends on the season and time of day — arriving early in the morning gives you more choices, while late afternoon pickups may have limited inventory.
Prices between companies can differ by $10 to $30 per day for the same vehicle type, so comparing quotes before you travel is worth the time. Most companies offer loyalty programs that provide discounts or free upgrades if you rent frequently. If you're a member of AAA, AARP, or a military branch, ask about member discounts at the rental desk — these can reduce your rate by 10 to 20 percent.
How to reserve a car before you arrive
Booking online or by phone before your trip locks in a lower rate than paying at the airport counter. Visit each company's website directly, or use a travel booking site like Kayak, Expedia, or Autoslash to compare prices across all six companies at once. When you book, you'll need your driver's license number, the dates and times you need the car, and a credit card to hold the reservation.
Most companies allow you to modify or cancel your reservation up to 24 hours before pickup without penalty, though some discount rates are non-refundable. Read the cancellation policy before you confirm. When you arrive at HNL, go to your rental company's desk with your confirmation number and driver's license. If you booked through a third-party site, bring that confirmation as well — the rental company will have your reservation in their system, but having the booking email speeds up the process.
Understanding insurance and damage coverage
Rental car companies offer collision damage waiver (CDW) or loss damage waiver (LDW) coverage, which protects you if the car is damaged or stolen. The cost is typically $15 to $30 per day. Before you buy this coverage, check whether your personal auto insurance or credit card already covers rental cars — many do. Call your insurance company or credit card issuer before you travel to confirm what's included and what isn't.
If your insurance or credit card covers rental damage, you can decline the rental company's coverage and save money. If you don't have coverage elsewhere, purchasing it from the rental company is the safer choice. Hawaii has a high rate of rental car break-ins, particularly in parking lots at popular tourist destinations, so comprehensive coverage that includes theft is worth considering. Read the fine print of whatever coverage you choose — some policies exclude certain types of damage, like damage to the undercarriage or windshield.
Fuel and return procedures at HNL
When you rent a car, you'll receive it with a full tank of fuel. You must return it with a full tank, or the rental company will charge you for the missing fuel at a rate that's typically $5 to $8 per gallon — roughly double what you'd pay at a regular gas station. Fill up your tank at a Shell, Chevron, or Tesoro station on Nimitz Highway, about 5 to 10 minutes from the rental facility, before you return the car.
Return the car to the same rental facility where you picked it up. Most companies accept returns 24 hours a day, though the desk may be unstaffed late at night — you'll park the car in a designated lot and leave the keys in a drop box. Take photos of the car's condition before you return it, showing the fuel gauge, odometer, and any existing damage. This protects you if the rental company later claims you caused damage you didn't cause. The company will inspect the car and email you a final receipt within a few days.
Driving in Honolulu and around Oahu
Honolulu traffic is heaviest during morning rush hour (6:30 to 9:00 a.m.) and evening rush hour (3:30 to 6:30 p.m.), particularly on H-1 and H-3 highways. Avoid these times if possible. Speed limits on highways are 55 mph unless posted otherwise. Parking in Honolulu is paid in most areas — bring quarters or use a parking app like SpotHero. Many beaches and hiking trailheads have free parking, but theft from rental cars is common, so don't leave valuables visible in the vehicle.
If you're driving around the island, keep in mind that distances are deceptive — the drive from Honolulu to the North Shore is about 45 minutes, and the drive to the windward side can take an hour or more depending on traffic. Gas stations are available throughout Oahu, but they're less frequent on the windward side, so fill up before you leave town. Rental cars are not permitted on some private roads, and four-wheel-drive vehicles are required for certain unpaved access roads — check with your rental company about where you're allowed to drive.
What to do if something goes wrong with your rental
If the car breaks down or you get a flat tire, call the rental company's roadside information number — it's on your rental agreement and on a sticker inside the car. Most companies will send a tow truck or replace the tire at no cost to you. If you're in an accident, don't admit fault. Call the police (911) if anyone is injured, and call the rental company when ready. Take photos of the damage, get the other driver's insurance information, and file a police report if the other driver was at fault.
If you damage the car and you purchased the rental company's coverage, the company will handle the claim. If you didn't purchase coverage and your personal insurance doesn't cover it, you'll be responsible for the repair cost. This can range from a few hundred dollars for minor damage to several thousand for major damage. If you have a dispute with the rental company over damage charges, contact your credit card company — many credit cards offer purchase protection that covers rental car disputes.
Frequently Asked Questions
Do I need an international driver's license to rent a car at HNL?
No, a valid driver's license from your home country is sufficient. If your license is not in English, bring an International Driving Permit (IDP) as well — it's a translation of your license and helps if you're stopped by police. You can obtain an IDP from your home country's automobile association before you travel.
Can I rent a car if I'm under 25?
Yes, but most companies charge an additional fee of $15 to $25 per day for drivers under 25. Some companies have a minimum age of 21, while others require drivers to be 25 or older. Check the rental company's age policy when you book. Having a credit card in your own name helps — some companies won't rent to drivers under 25 who only have a debit card.
What happens if I return the car late?
Late fees vary by company but typically range from $25 to $50 for the first hour, then additional hourly or daily charges. If you're running late, call the rental company as soon as possible — some will waive or reduce the fee if you notify them in advance. Check your rental agreement for the exact late fee policy before you pick up the car.
Can I take a rental car from HNL to the other Hawaiian islands?
No, rental cars from HNL cannot leave Oahu. If you want to drive on another island, you'll need to rent a car at that island's airport. Most rental companies have locations on Maui, Hawaii (Big Island), and Kauai, so you can reserve a car there in advance.
Is it cheaper to rent a car at the airport or in Honolulu?
Off-airport rental locations in Honolulu sometimes have lower rates than HNL, but you'll need to factor in the cost and time of getting to that location. If you're staying in Waikiki, an off-airport rental might save $5 to $15 per day, but you'll spend time and money on transportation. For most travelers, renting at HNL is more convenient, even if the rate is slightly higher.
