How does the Hertz and Amex Platinum ‘4 hour grace period’ work?

Having rented a few cars this Summer, I thought it was worth running through one of the lesser known benefits of The Platinum Card from American Express.

Most people know that Amex Platinum comes with comprehensive car hire insurance. You don’t need to agree to anything that the rental company tries to sell you. I have claimed on this a few times over the years and never had a problem. The car hire company charges you and you reclaim the bill from American Express.

American Express Platinum '4 hour Hertz grace period'

Platinum also comes with elite status at Hertz and Avis, although I don’t value this much. It is worth having if you regularly rent from busy depots as it usually allows you to ignore the queue and pick up your keys from a separate desk.

The Hertz ‘4 hour’ deal is something separate. It allows you to make your final rental day a 28 hour one.

Let’s imagine that you pick up a car at 10am on Friday to return at 2pm on Monday.

Car rental companies treat this as a 4 day rental.

With Hertz, as long as you use the Amex Platinum CDP code of 633306, it prices as a 3 day rental. This is because you get a four grace period on your final day.

Where is the four hour grace period available?

According to Hertz:

“A 4-hour no charge grace period before an extra day charge is applied when returning the vehicle in Hertz Corporate Europe locations, the U.S., Canada, Latin America, Middle East (with exception of UAE and Bahrain who offer 2 hours grace period) and selected European Franchise countries (see participating countries). Asia, with the exception of China, offers a 2-hour no charge grace period, except on optional extras like portable phones.”

Here is an example.

Compare two bookings using the Amex Platinum code:

All of these quotes are taken from the UK Hertz website which is here.

This is a Hertz rental of exactly three days using the Amex Platinum discount code, showing £72.35 as the price.

American Express Platinum '4 hour Hertz grace period'

This is a Hertz rental of three days and four hours, using the Amex Platinum discount code:

American Express Platinum '4 hour Hertz grace period'

As you can see, there is no difference. It is still £72.35.

Compare two bookings WITHOUT the Amex Platinum code:

To prove that the Amex code is making a difference, here is the same Hertz rental of exactly three days WITHOUT using the Amex Platinum discount code. You will see that the Platinum code has saved us £11.93 which is OK but not a fortune.

American Express Platinum '4 hour Hertz grace period'

This is a Hertz rental of three days and four hours WITHOUT using the Amex Platinum discount code:

American Express Platinum '4 hour Hertz grace period'

You will see that the price has shot up because you are now paying for a fourth day, even though you are returning the car just four hours into the fourth day.

For this rental, the Amex Platinum code saves us (£129.22 – £72.35) £56.87, or 44%.

Conclusion

The American Express Platinum / Hertz ‘four hour waiver’ seems like a very niche benefit, and one that you can easily overlook.

If it fits around your schedule, however, it can lead to substantial savings.

PS. You can often make additional savings by using another Amex Platinum discount code – 211762. I’m not sure where this is from, but it comes up as ‘Platinum Card from Amex’ whereas the code used above comes up as ‘Amex Platinum EMEA’.

In our example above, using code 211762 drops the price from £72.35 to £64.38.

    211762 is the Australian Plat AMEX version.

    • Danny says:

      That might explain why its cheaper. Given Australian rates often seem to be cheaper on Hertz.

    • pauldb says:

      I’m pretty sure it’s the US Plat CDP, but it can be worthwhile trying it on the Hertz Oz site as well for different rates.

      • Charlieface says:

        Yes US Plat 25% off, but I’ve never had anyone check it’s not a US card

  • pauldb says:

    Unfortunately the usefulness of this is squeezed to only the cases where Hertz are already competitive. In this case Avis will sell you four full days for £72.

    • Rob says:

      Hertz is £63 on the dates I used if you want a Group B car. I took a Group A for my example, but Group A cars cost more – despite being smaller – because there are very few of them in most fleets.

  • Ken says:

    Beware
    Doesn’t work in all European countries & locations.
    Certainly doesn’t work at Porto airport and I think Portugal full stop. Hard to actually find out where it does work.

    • Rob says:

      I’ve never not had it work, as long as its a corporate Hertz location. Franchised offices might not work.

      • Alan says:

        It works at some but not all, definitely only in a limited number of countries though that would be worth adding to the article?…

      • Philip White says:

        I struggle to make it work in Germany. Max is always 2 hours.

        • lgflyer says:

          My experience in Bremen Airport in February:
          – Booked a pre-paid rental for 2 days and 4 hours and it priced ok as 2 days.
          – On the contract the price had increased to 3 days so had to explain the promotion to the agent and he applied a manual discount so that the total was the same amount I had already pre-paid.
          – On returning the car the invoice showed the correct charge (2 days) minus the manual discount applied by the agent, so in effect it was just a 1 day charge…
          – Since it was a pre-paid rental I didn’t get any refund, but if it would had been a pay-on-return rental I presume I would have been charged just for 1 day…

  • MARK C says:

    Where and how can you transfer hertz points to an airline / hotel please? I’ve done it previously but the option seems to have disappeared. Tia

    • Rob says:

      It has come off the UK website. It was, at least last time I checked, still possible off the US website.

      • ian_h says:

        I think its gone from the US site too presumably not wanting to pay other programs for points whilst they have their issues. If anyone has a stored url -that might work …..

      • MARK CLEVERLY says:

        Yeah i tried that too. The “Exchange my points” seems to have disappeared.

  • Robert says:

    The 4 hour grace is a fantastic benefit which I’ve often used in LA, and also means it’s Hertz that get my business there, while I would usually use Avis in the UK (or Sixt occasionally).
    Rob your comments re Platinum giving you status with Avis, you don’t mean president Club do you?

  • Yuff says:

    Anyone know if the car insurance benefits at curve metal are any good?
    Had Amex plat but waiting 6 months to apply for business which is up next month.
    Could apply for my wife this month but needThe insurance for Tuesday.

    • pauldb says:

      The quicker alternative is third party cover which is pretty cheap. I had to make a claim through https://www.carhireexcess.com/ in February and it was surprisingly painless.

    • Oh! Matron! says:

      Rob:

      Would be great to see a Amex Plat / Gold / Curve / SPG insurance benefits /coverage for hire cars article

    • the_real_a says:

      The issue seems to be that vehicles must be below £20k value. A lot of people seem to like to hire expensive cars abroad and find this restrictive.

      • Yuff says:

        Is that for the curve metal car insurance?

      • Lady London says:

        The problem is also that the hire company may force you to take a more expensive vehicle because that’s all they’ve got available on the day.

        This can cause all sorts of complications (higher amount reserved off your credit card, possible failure to qualify for a promotion restricted to particular grades of car, not allowed to take a nicer car across some borders, etc), as well as the list price of the car invalidating potential limits on your car hire excess cover.

    • e14 says:

      You need to pay with curve so okay if you are doing a prepay with say Expedia or even direct with the rental co. Not so good if it’s a contract pay at the end as you’ll need to have a hold put on the curve card which really doesn’t work well

  • Nori says:

    It didn’t work at franchise locations for me despite the website quoting otherwise. I had to make a complaint to get a refunded for the extra monies charged.
    But when it works, it’s a brilliant deal.

  • Charlieface says:

    Please note, it’s much better to add the hours on when booking rather than hoping the branch remembers not to charge you when checking back in.
    Also if you’re up against the 28 day maximum for short term rentals, you can’t do it unless you break the booking into two

    • Cam says:

      I have had it denied when asking at the counter (eg, when picking up the car), but it works just fine when making the booking. It’s a great small benefit – definitely drives me to Hertz over the competition, at the margin (and Amex / Hertz pricing is in the US and UK is in recent experience better than the other majors). And prices are almost always better on websites other than the UK, even when renting in the UK.

    • Lady London says:

      Sounds like it would be a good idea to book for the times including the extra hours, but also to add a note to the booking that you are using the extra Amex hours either at the time of booking or phoning up after making the booking.
