How can I upgrade my rental car?

Chatref Team3 min read / Updated June 18, 2026

To upgrade your rental car, check online availability, call the rental desk, or use our AI assistant that searches real-time inventory and applies your upgrade instantly. With a better rental car, you enjoy extra space, premium features, and a smoother ride. Upgrade costs vary by class and date, and our chat can process your request in seconds.

Check for upgrade options online

Log in to your reservation on our website or app and look for upgrade rental car options under the "Manage Booking" section. You will see a list of available vehicle classes and nightly upgrade fees. This is often the fastest way to see what is open for your dates and pre-pay before you arrive.

If the system shows no availability, don't give up yet. Cancellations and fleet changes happen daily, so check back during the 48 hours before pickup.

Use our AI assistant for real-time upgrades

Our website’s chat assistant, built on Chatref’s knowledge-base, can show you how to get a better rental car without waiting on hold. The AI agent pulls your booking, checks live inventory, and walks you through available upgrade rental car options. Its custom actions let it apply the upgrade to your reservation and send a confirmation right in the chat.

Simply type “upgrade my car” or “can I get a nicer vehicle” and the agent will guide you through the steps. It resolves most requests in under a minute, and if you prefer a human, it hands off to an available agent with full context.

Call or visit the rental counter

If you prefer to speak with a person, our reservations team can search for upgrades and explain any promotions. At the counter, upgrades are first-come, first-served. Mention your loyalty membership or any corporate codes - sometimes these unlock discounted upgrade rates. The AI assistant can also provide the counter’s phone number and directions instantly.

Upgrade costs and vehicle classes

The price to upgrade a rental car depends on the base class you booked, the class you want, rental length, and seasonal demand. A jump from intermediate to standard SUV might cost $15-25 per day, while a full-size to a luxury sedan can run $40-60 per day.

Common vehicle classes for upgrades:

  • Compact to mid-size
  • Mid-size to full-size
  • Full-size to premium SUV
  • Any class to a luxury or specialty vehicle

Loyalty points can sometimes cover upgrade fees, and last-minute upgrades at the counter may be offered at a discount if premium cars are sitting idle.

What else can our AI assistant do?

Beyond upgrades, the Chatref-powered chatbot can answer questions about insurance, fuel policies, toll passes, and after-hours returns. It learns from our entire knowledge base, so its answers are always grounded in our official policies - no guesswork. If it needs your account details to proceed, it uses secure custom actions to retrieve them without human intervention.

FAQ

Can I upgrade my rental car after booking?
Yes. Use the website, app, AI assistant, or call us. Upgrades after booking are subject to availability and the price difference for the remaining rental period. If you upgrade after pickup, return to the rental location to swap vehicles; fees are calculated on the spot.

What are the benefits of upgrading to a premium rental car?
Premium vehicles typically offer more legroom, leather seats, advanced driver-assistance systems, better fuel efficiency, and a quieter cabin. Upgrading also gives you a specific vehicle model you may prefer for a long trip or a business occasion.

How much does it cost to upgrade a rental car?
Cost depends on the class difference, rental length, and location. On average, expect $15-60 per day. Some upgrades can be covered by loyalty points, and occasional promotions offer flat-rate upgrades later in the booking window.

What types of upgrades are available for rental cars?
You can upgrade size (e.g., mid-size to full-size), category (SUV, van, truck), or premium tier (luxury sedan, convertible, high-end SUV). Availability is location-specific, so ask our AI assistant or check your reservation online for the exact upgrade rental car options at your pickup branch.
