Costco Car Rental Cancellation: A Simple Guide to Getting a Full Refund

Costco Travel offers some of the most competitive car rental rates available. But travel plans can change, leading to a common question: what is Costco's car rental cancellation policy? The good news is that for most bookings, Costco's policy is incredibly flexible and customer-friendly. This guide will explain the policy and show you exactly how to cancel your reservation.

The Short Answer

Yes, you can cancel most Costco car rental reservations at any time without a fee. The vast majority of bookings are "pay-later," meaning you haven't paid anything upfront. Since no money was exchanged, there is no penalty for canceling before your pickup time.

The Problem: Fear of Hidden Fees and Penalties

Many travelers are hesitant to book in advance because they fear losing money if their plans change. Other travel sites can have confusing cancellation policies, with some charging fees or forfeiting your prepayment if you don't cancel within a specific window. You need to know if booking through Costco locks you into a similar, restrictive policy.

The Golden Rule of Costco Car Rentals

For most standard car rental reservations made through Costco Travel, there is NO CANCELLATION FEE.

Costco works with the major car rental companies (like Avis, Budget, Alamo, and Enterprise). When you book through Costco, you are making a "pay-later" reservation. You simply reserve the vehicle at Costco's negotiated rate, and you pay the rental company directly when you pick up the car. Since no money has changed hands, there is nothing to refund and no penalty for canceling.

How to Cancel Your Costco Car Rental Reservation: A Step-by-Step Guide

The process is simple and can be done online in just a few minutes.

Go to the Costco Travel website (CostcoTravel.com in the US or CostcoTravel.ca in Canada).
Log in to your Costco account.
Navigate to the "My Trips" section in your account dashboard.
Find your upcoming car rental reservation and click on it to view the details.
Look for a prominent "Cancel" button or link and click it.
The system will ask you to confirm the cancellation. Once you confirm, the reservation will be canceled.
You will receive a confirmation email . Keep this email for your records.

That's it. Your reservation is canceled, and you owe nothing.

The Important Exception: "Pay Now" or Pre-Paid Reservations

While the vast majority of Costco car rentals are "pay-later," some rental companies occasionally offer a slightly lower "Pay Now" rate through the Costco portal. If you choose one of these pre-paid rates, the cancellation policy is determined by the rental car company (e.g., Avis, Budget), not by Costco.

These policies typically state:

If you cancel more than 24 hours before pickup, you will usually get a full refund, but may be charged a small administrative fee (e.g., $25).
If you cancel within 24 hours of pickup, or if you are a "no-show," you may forfeit the entire prepayment.

How to know if your booking is pre-paid: It will be clearly marked as "Pay Now" during the booking process, and you will have to enter your credit card information to pay at the time of booking. If you didn't pay anything when you booked, you have a standard, fee-free cancellable reservation.

Frequently Asked Questions

What happens if I forget to cancel and I'm a "no-show"?

For a standard "pay-later" reservation, there is typically no penalty if you are a no-show. The reservation will simply be canceled automatically after the pickup time has passed. However, it is a good courtesy to cancel as soon as you know your plans have changed to free up the vehicle for other renters.

Can I modify my reservation instead of canceling?

Yes. If you need to change the dates or car type, you can often modify your booking online through the "My Trips" portal. However, changing the dates will cause the price to be recalculated at the current rates, which may be higher or lower than your original booking.

Does this same policy apply to Costco Travel vacation packages or cruises?

No. This fee-free cancellation policy is specific to most car rental bookings. Vacation packages, cruises, and hotel bookings have their own, much more restrictive cancellation policies and deadlines that you must review carefully before purchasing.

Conclusion: Book with Confidence

Costco's car rental cancellation policy is one of the most flexible and consumer-friendly in the travel industry. For standard, "pay-later" reservations, the ability to cancel at any time without a fee provides incredible peace of mind. It allows you to book your rental car well in advance, risk-free, and even re-book if you find a lower rate later. Just be mindful of the rare "Pay Now" offers and their specific policies. For the overwhelming majority of users, booking a car rental through Costco is a safe, smart, and worry-free choice.
