Yes, you can usually change your rental car pick-up time, but the process, potential fees, and availability depend heavily on the rental company's policy, how you booked, and how close you are to your original reservation time. The key is to act quickly, as last-minute changes are more restrictive and costly.
The easiest scenario is modifying your reservation well in advance through the same channel you used to book—like the rental company’s website or app. Most major companies allow free modifications if you're changing your time by a few hours on the same day. However, changing the pick-up date or making a last-minute alteration can be more complex.
Factors That Influence the Change:
If you need to pick up the car later than scheduled, the most important step is to call the rental location directly. Explain your situation. They can note your account and often hold the car if they know you're en route.
Here’s a quick reference for policies from major U.S. rental companies:
| Rental Company | Policy Overview (Subject to Change) | Key Consideration |
|---|---|---|
| Enterprise | Allows free modifications online or via app for most reservations. | Pre-paid reservations require calling the location; late pick-ups should call directly. |
| Hertz | Changes can be made online if the rental location is open. | Significant changes to time/date may alter the final rate. A 29-minute grace period is standard. |
| Avis | Modifications are permitted online, but the rental location must be open. | Rate is not guaranteed if the change is substantial. Pre-paid bookings are typically non-refundable. |
| Budget | Similar to Avis, changes are allowed online for flexible rates. | Contact the location directly for late arrivals to avoid a no-show cancellation. |
| Alamo | Free changes can be made online up to 24 hours before rental. | A no-show fee may apply if you don't pick up the car and fail to cancel. |
The best strategy is to always review the terms and conditions of your specific reservation before booking. Opt for a flexible rate if you think your plans might change.

From my experience, it’s totally doable, but don’t just show up late. The big thing is communication. If I know I'm running behind, I immediately pull up the app and try to change it there. If that's not an option, I call the actual rental office—not the general 800 number—and talk to a person. Telling them you're stuck in traffic can make all the difference between them holding your car and giving it away. It’s all about avoiding that no-show fee.

As a frequent business renter, my advice is to prioritize booking directly with the company and selecting a flexible rate. This simplifies modifications immensely. I often adjust my pick-up time via the airline app while taxiing to the gate. The critical rule is that a change of more than a few hours may recalculate your rate based on current availability. For a seamless experience, direct bookings and flexible terms are non-negotiable.

I learned this the hard way on a family vacation. We pre-paid for a minivan to save money, but our flight was delayed. When we finally arrived, the counter was closed and our reservation was canceled. No car, no refund. Now, I never pre-pay if there’s any chance our travel schedule could be tight. It’s worth paying a little more for a rate that lets you change the time without penalty, especially when kids are involved.
