What you get when you rent from Sixt at Lihue

Sixt operates a rental counter at Lihue Airport (LIH) on Kauai's east side, about 2 miles from the terminal. You can pick up a car when ready after landing and return it before your flight without leaving the airport grounds. Sixt's fleet at Lihue includes economy cars, SUVs, and vans — the specific models available depend on the season and how far ahead you book.

The rental counter is located in the main terminal building. After you collect your luggage and clear the airport, follow signs for car rental agencies. Sixt shares a common area with other major rental companies, so you will see their signage clearly. The process from counter to car typically takes 15 to 20 minutes if you have your driver's license, credit card, and reservation confirmation ready.

Key Takeaways

  • Sixt's Lihue counter is inside the terminal, about 2 miles from the runway, and you can return the car on the way to your flight.
  • You need a valid driver's license, credit card in your name, and proof of insurance or the option to buy Sixt's coverage before you reach the counter.
  • Rates vary by season and how far in advance you book; summer and holiday weeks are more expensive than shoulder seasons.
  • Sixt charges a daily facility fee at Lihue Airport in addition to the base rental rate, and this fee appears on your final bill.
  • Returning the car with a full tank of fuel costs less than buying fuel through Sixt's prepay option or paying per-gallon at return.

Documents and requirements you need at pickup

Bring your valid driver's license — a U.S. state license, passport card, or international driving permit all work. Sixt will scan it and verify your name matches your reservation. You must also have a credit card in your own name; debit cards are not accepted as the primary payment method, though some locations accept them as a secondary option.

You will need proof of insurance. If you carry your own auto insurance, bring a copy of your policy or a declaration page showing your coverage limits. If you do not have insurance or prefer not to use it, Sixt will offer you a damage waiver and liability coverage at the counter. The cost of this coverage varies but typically runs $15 to $25 per day depending on the vehicle class and what protection level you choose.

Have your reservation confirmation number ready — you can show it on your phone or print it. If you booked through a third-party site like Kayak or Autoslash, bring that confirmation as well as your Sixt confirmation, because the counter agent will need to match them.

How Sixt's pricing works at Lihue Airport

Sixt charges three separate costs: the daily rental rate, a daily airport facility fee, and insurance or damage coverage if you buy it. The rental rate itself varies by vehicle type and season. An economy car in the off-season might run $35 to $50 per day, while the same car in July or December could be $60 to $90 per day. SUVs and larger vehicles cost more — expect to add $20 to $40 per day for an SUV depending on the season.

The airport facility fee at Lihue is a separate charge that Sixt adds to every rental. This fee covers the cost of operating the counter and lot at the airport. It is not negotiable and appears as a line item on your final bill. The exact amount depends on Sixt's current agreement with the airport authority, but plan for an additional $5 to $8 per day.

Fuel is your choice. You can return the car with a full tank and pay nothing extra. You can prepay for a full tank when you pick up the car, which locks in a per-gallon rate that is usually higher than what you would pay at a gas station. Or you can return the car with whatever fuel is left and pay Sixt's per-gallon rate at return, which is the most expensive option. Most renters find it cheapest to fill up at a gas station near the airport before returning the car.

Booking directly with Sixt versus third-party sites

You can book through Sixt's website (sixt.com), through a third-party aggregator like Kayak or Autoslash, or by calling Sixt directly. Booking directly with Sixt sometimes shows lower rates because you avoid the markup that third-party sites add. However, third-party sites occasionally have flash sales or bundle deals that beat Sixt's direct price.

The trade-off is customer service. If you book through Sixt directly and something goes wrong — a price change, a vehicle swap, a cancellation — you contact Sixt and they handle it when ready. If you book through a third party and there is a problem, you may have to contact both the third party and Sixt to resolve it, which takes longer. For airport pickups where timing matters, booking directly reduces friction.

Check both routes before you book. Search for your dates on Sixt.com, note the total price, then search the same dates on Kayak or Autoslash. If the third-party price is lower by more than $20 to $30 for your entire rental, it may be worth the extra step. If the prices are close, book directly with Sixt.

Insurance and damage coverage decisions

Your own auto insurance may cover rental cars, but you need to verify this before you arrive. Call your insurance company and ask whether your policy covers rentals in Hawaii. Some policies do; some exclude rentals entirely; some cover rentals only in the mainland U.S. Get a written confirmation or note the date and agent name so you have proof if you need to file a claim.

If your insurance covers rentals, you can decline Sixt's damage waiver at the counter and save $15 to $25 per day. If your insurance does not cover rentals or you want extra protection, buy Sixt's coverage. The basic damage waiver covers collision and theft but usually has a deductible of $1,000 to $2,500. Sixt also offers a zero-deductible option for an additional fee.

Credit card companies sometimes offer rental car coverage if you charge the rental to that card. American Express and some premium Visa and Mastercard products include this. Check your card's benefits guide or call the issuer before your trip. If your card covers rentals, you can skip Sixt's coverage entirely — but read the fine print, because some card benefits exclude Hawaii or have other restrictions.

Returning the car and avoiding extra charges

Return the car to the same Sixt lot at Lihue Airport. The return process is straightforward: drive to the lot, park in a Sixt space, and an agent will meet you. They will inspect the car for damage, check the fuel level, and print your final bill. This usually takes 5 to 10 minutes. Keep your receipt — you will need it if you have questions about charges later.

The most common extra charges are fuel overage fees and damage claims. To avoid fuel charges, fill the tank at a gas station within a mile or two of the airport before you return the car. Sixt will check the fuel gauge and charge you only if it is below full. For damage, inspect the car carefully when you pick it up and photograph any existing dents, scratches, or stains. Point these out to the agent at pickup so they are documented on your contract. This protects you from being charged for damage you did not cause.

If you are returning the car after hours, Sixt has a night drop-off option. You park the car in a designated spot, lock it, and drop the keys in a find box. The agent will inspect it the next morning and email you the final bill. This works well if your flight leaves very early, but you lose the chance to dispute any damage charges on the spot.

Frequently Asked Questions

Can I pick up a car at Lihue and return it at a different Sixt location on Kauai?

Sixt operates only at Lihue Airport on Kauai, so there is no other Sixt location to return to. If you need to return a car at a different island, you would need to book with a different rental company that has locations on that island. Check whether Sixt has a presence on your destination island before you book a one-way rental.

What if I need to extend my rental after I have already picked up the car?

Call Sixt's customer service line or visit the Lihue counter if you are still on the island. Sixt can extend your rental if cars are available, though rates for the extra days may be higher than your original rate. Extensions are not may provide, especially during peak season, so plan your rental length carefully before you pick up the car.

Does Sixt charge a fee if I return the car early?

No, Sixt does not charge an early return penalty. If you return the car before your reservation end date, you pay only for the days you used it. This makes it safe to book a longer rental if you are unsure about your plans — you can return early without losing money.

What happens if I get a traffic ticket or parking violation while renting from Sixt?

Sixt will forward any tickets or violations to you after your rental ends. You are responsible for paying the fine. The ticket is issued to you, not to Sixt, so Sixt's insurance does not cover it. Pay any fines promptly to avoid additional penalties or collection action.

Can I add an additional driver at the Lihue counter, or do I have to book it in advance?

You can add a driver at the counter, but Sixt charges a daily fee for each additional driver — typically $10 to $15 per day. The additional driver must have a valid license and be present at pickup. It is usually cheaper to add the driver when you book online, so check the price difference before you arrive at the counter.
