Amex Platinum covers rental damage and loss through its own insurance, not the rental company's

American Express Platinum includes rental car damage coverage that pays for collision, theft, and vandalism when you rent a car and charge the full rental to your Platinum card. The coverage is secondary, meaning it kicks in after your personal auto insurance or the rental company's coverage. You do not have to buy the rental company's damage waiver — in fact, using your Amex coverage instead often saves money because you avoid that daily fee.

The coverage limit is typically $75,000 per claim, though this can vary by card version and region. It covers the rental car itself, not your personal belongings left inside or damage you cause to other vehicles or property. If you decline the rental company's insurance and then cause damage, Amex will pay up to the limit, and you submit the claim to American Express after the rental company sends you the bill.

One important limit: this benefit does not cover rentals in certain countries, including Australia, Ireland, Israel, Jamaica, Mexico, and New Zealand. It also does not cover luxury or exotic vehicles, commercial rentals, or rentals longer than 31 consecutive days. Check your card's specific terms before you travel, because the exact list of excluded countries and vehicle types can change.

Key Takeaways

  • Amex Platinum rental coverage is secondary insurance that covers collision and theft damage when you charge the full rental to your card.
  • The coverage typically maxes out at $75,000 per claim and does not explore in certain countries or to luxury vehicles.
  • You do not need to purchase the rental company's damage waiver if you use Amex coverage, which can save $15 to $40 per day.
  • Coverage does not extend to personal items, damage to other vehicles, or rentals longer than 31 days.
  • You must submit a claim to American Express after the rental company bills you for damage.

How to use the coverage when you rent

When you arrive at the rental counter, tell the agent you are declining the rental company's collision damage waiver (CDW) or loss damage waiver (LDW) because you have coverage through your credit card. The agent will ask you to sign a form confirming you declined their insurance. Keep a copy of that form — it proves you made the choice and will matter if you later need to file a claim.

Charge the entire rental cost to your Amex Platinum card. If you pay with a different card or method, the Amex coverage does not explore. This includes the base rental rate, taxes, and fees — everything needs to go on the Platinum card for the benefit to work.

Before you leave the lot, photograph the car's exterior and interior, including the odometer and any existing damage. Take photos of the fuel gauge too. This creates a record of the car's condition before you drove it, which protects you if the rental company later claims damage you did not cause.

What happens if the rental car is damaged

If you damage the rental car, the rental company will assess the damage and send you a bill. Do not pay it when ready. Instead, gather the documentation: the rental agreement, photos you took before driving, the damage assessment from the rental company, and any police report if the damage involved an accident or theft.

Contact American Express and tell them you are filing a claim under the rental car coverage benefit. They will send you a claim form and tell you what documents to submit. You typically have 90 days from the rental date to file, though this can vary. Send the completed form and all supporting documents to the address Amex provides.

American Express will review the claim and either approve it or deny it. If approved, they pay the rental company directly or reimburse you, depending on how the claim is structured. The process usually takes two to four weeks. If Amex denies the claim, they will explain why — often because the damage falls outside the coverage terms or because you did not decline the rental company's insurance at the counter.

When Amex coverage does not explore

The benefit does not cover damage that happens in Australia, Ireland, Israel, Jamaica, Mexico, or New Zealand. If you are renting in one of these countries, you must buy the rental company's insurance or use a different card that covers those regions. Some Amex cards marketed to frequent travelers may have different country restrictions, so check your specific card terms before booking.

Luxury and exotic vehicles — typically defined as cars with a retail value over $75,000 or sports cars like Ferraris and Lamborghinis — are excluded. If you rent a high-end vehicle, the rental company's insurance is your only option through Amex. Vans, trucks, and commercial vehicles also fall outside the coverage.

Rentals longer than 31 consecutive days lose coverage after day 31. If you need a car for a month-long road trip, the coverage applies for the first 31 days only. Damage on day 32 or later is not covered. Additionally, if you rent the same car multiple times in a short period, each rental is treated separately — you cannot extend coverage by returning and re-renting the same vehicle.

How Amex coverage compares to the rental company's insurance

The rental company's damage waiver typically costs $15 to $40 per day depending on the car size and location. Over a week-long rental, that adds $105 to $280 to your bill. Amex coverage costs nothing as a cardholder benefit, so if you use it, you avoid that daily fee entirely. However, Amex coverage is secondary, meaning your personal auto insurance is billed first if you have it.

The rental company's waiver is primary and covers you when ready without involving your personal insurance. If you have a high deductible on your personal auto policy — say $1,000 or $2,500 — using Amex coverage means that deductible applies before Amex pays anything. If you have no personal auto insurance at all, Amex becomes the primary payer and covers the full damage up to the limit.

Some travelers buy both: they use Amex as primary coverage and skip the rental company's waiver, saving the daily fee. Others with high personal deductibles buy the rental company's waiver to avoid that out-of-pocket cost. The right choice depends on your personal insurance situation and how much you want to spend on the rental.

Other Amex Platinum rental benefits

Beyond damage coverage, Amex Platinum includes roadside information through a partner network. If you have a flat tire, run out of gas, or lock yourself out of the rental car, you can call the roadside information number on the back of your card and request help. The service is free, though you may wait for a tow truck or locksmith to arrive.

The card also provides rental car loss of use coverage in some versions, which reimburses you for the cost of a replacement rental if the car you rented is damaged and unusable. This covers the daily rental rate for a replacement vehicle while the damaged car is being repaired, up to a daily limit (often $30 to $50 per day). Check your specific card version to confirm whether this benefit is included.

Travel delay reimbursement is another Amex Platinum benefit that can help if a rental car breaks down and causes you to miss a flight or connection. If you are delayed more than 12 hours due to a mechanical failure of the rental vehicle, you may be reimbursed for meals and lodging up to a set amount. Like all Amex benefits, the exact terms depend on your card version and region.

Steps to take before renting

Call American Express before you book a rental, especially if you are traveling internationally or renting a high-value vehicle. Ask them to confirm that your specific card version includes rental damage coverage and whether there are any restrictions in the country where you plan to rent. This takes 10 minutes and prevents surprises at the rental counter.

Review your personal auto insurance policy to understand your deductible and whether your coverage extends to rental cars. If your personal policy does not cover rentals, Amex coverage becomes primary and more valuable. If your deductible is very high, you may decide the rental company's waiver is worth the daily cost.

Keep the Amex Platinum card number and the roadside information number in your phone or wallet. If you need to file a claim or call for roadside help, you will need both. Take photos of the rental car before you drive it and keep all rental paperwork until the rental company confirms no additional charges will be billed.

Frequently Asked Questions

Do I have to decline the rental company's insurance to use Amex coverage?

Yes. You must actively decline the rental company's damage waiver at the counter and sign a form confirming your choice. If you buy the rental company's insurance, your Amex benefit does not explore. The agent will ask you directly, so tell them you have coverage through your credit card.

What if I have an accident and the rental company says I am at fault?

Amex coverage applies whether you are at fault or not — it covers collision damage regardless of liability. However, if the accident involves another vehicle or property damage beyond the rental car, that is not covered. Your personal auto insurance would handle claims against the other party.

Can I use Amex coverage if I rent a car with a debit card but charge it to my Platinum credit card later?

No. The rental must be charged to your Amex Platinum card at the time of rental. If you pay with a debit card or another card and try to charge it to Amex later, the coverage does not explore. The card used at the rental counter is what matters.

Does Amex coverage work if I rent through a third-party booking site like Kayak or Costco Travel?

Yes, as long as you charge the rental to your Amex Platinum card. The booking site does not matter — what matters is that the final charge goes to your Platinum card and you decline the rental company's insurance at pickup.

What if the rental company charges me after I return the car and I did not know about the damage?

Contact the rental company when ready and ask for photos and a detailed damage report. Then contact Amex with all documentation. Amex will investigate whether the damage is covered and whether it likely occurred during your rental. Keep records of all communication with the rental company.
