How to rebook a car rental after a price drop

How do you monitor a car rental rate after you book?

Start with the booking you hold. Each supplier provides a self-service area for it: Avis names it Manage Booking [3], Budget names it View / Modify / Cancel [4], and Enterprise names it View/Modify/Cancel Reservation [5]. Enterprise's reservations help section says it covers making, modifying and cancelling a reservation [5].

Budget's sign-in screen states that login is not required to complete a reservation [4]. Its member benefits terms, headed Best Rate Guarantee, say you create or log in to a Budget.com account to get the best rate [4].

Check which coupon or code produced any rate and what the cancellation deadline is. In Budget's coupon terms, the customer must provide the profile number associated with the coupon, and the reservation must be cancelled by the rental date or the coupon will be used [4].

When is a cheaper rate actually cheaper?

Compare the total, and keep the coupon's conditions attached to it. Budget's free-day coupon terms are used here as an illustration of how coupon conditions work, not as an offer you can book now: the page says "Rental must begin on or before 12/31/23" [4]. In those terms, the offer covered one day of the daily time and mileage charges, and taxes, the concession recovery fee, customer facility charges ($10 per contract in California) and fuel charges were extra [4]. Optional items such as LDW and other surcharges may also apply and be extra [4].

Those same terms say the coupon cannot be used for one-way rentals [4]. Under those terms, holiday and other blackout periods may apply; if a rental begins during a blackout period, the whole rental is blacked out and does not qualify for the coupon [4].

The coupon is one per rental and may not be used in conjunction with any other coupon, promotion or offer [4], and it is valid only at Budget locations in the contiguous U.S. excluding the New York Metro area [4].

Do cancellation terms decide whether rebooking pays?

They can. Budget's free-day coupon terms, quoted as an illustration of coupon mechanics, require an advance reservation and state that the reservation must be cancelled by the rental date or the coupon will be used [4]. Those terms also say coupons cannot be applied to completed rentals [4]. For the general distinction between rate types, see prepaid vs pay at counter and the cancellation and no-show policy guide.

Conditions also differ by location. Enterprise directs travellers outside the United States to a separate list of worldwide FAQs [5]. The Budget coupon described in those terms is valid only at Budget locations in the contiguous U.S. excluding the New York Metro area [4]. Budget also says renters must meet its age, driver and credit requirements; minimum age may vary by location, and an additional daily surcharge may apply for renters under 25 [4].

Do loyalty programmes change the comparison?

Budget's member benefits terms, headed Best Rate Guarantee, say you create or log in to a Budget.com account to get the best rate, then list exceptions: rates from other car rental companies; rates obtained through discounts, coupons, upgrade offers or pre-negotiated group, government, corporate, tour or insurance-replacement rentals; car rental included in a package rate; rates from auction or wholesale sites that do not display the car rental company's name until after purchase; and rates from a website that requires a member login to obtain the rate [4].

Budget presents One Click Reservations as a FastBreak member benefit [4]. Avis lists an Avis Preferred programme and a Best Price Pledge page under company information [3]. Enterprise presents its Enterprise Plus programme as the more you rent, the more rewards you earn [5].

Budget's customer care area links to a form for requesting miles and points for your rental and lists miles and points programmes among its partners [4].

Exceptions and limits

• Offer status. The Budget free-day coupon terms referenced throughout this page are quoted as an illustration of how coupon conditions work, not as an offer available now: the terms say "Rental must begin on or before 12/31/23" [4].
• Country. The three help pages cited here are in English, and Enterprise directs travellers outside the United States to separate worldwide FAQs [5]. The Budget coupon in those published terms is limited to the contiguous U.S. excluding the New York Metro area [4].
• Blackout dates. Under those Budget coupon terms, holiday and other blackout periods may apply, and a rental that begins during a blackout period is blacked out for the whole rental [4].
• Coupon consumption. The Budget coupon in those terms requires an advance reservation, is one per rental, cannot be combined with other coupons, promotions or offers, and is used up if the reservation is not cancelled by the rental date [4].
• Location rules. Minimum age may vary by location, an additional daily surcharge may apply for renters under 25, and renters must meet Budget's age, driver and credit requirements [4].
• Guarantee exceptions. Budget's Best Rate Guarantee terms exclude rates from other car rental companies, discounted, coupon, upgrade and pre-negotiated rates, package rates, auction and wholesale rates, and rates from sites that require a member login [4].

Frequently asked questions

Can I cancel a car rental and rebook at a lower price?

Avis, Budget and Enterprise all provide self-service areas for existing bookings, named Manage Booking, View / Modify / Cancel and View/Modify/Cancel Reservation [3] [4] [5]. Check the terms of the rate you hold: Budget's published coupon terms state that the reservation must be cancelled by the rental date or the coupon will be used [4].

Is the cheapest daily rate always the cheapest rental?

Not necessarily. In Budget's free-day coupon terms — quoted here as an illustration of how coupon conditions work, not as a current offer, since the terms say "Rental must begin on or before 12/31/23" — taxes, the concession recovery fee, customer facility charges ($10 per contract in California) and fuel charges are extra, and optional items such as LDW and other surcharges may be extra too [4].

Will I lose my coupon if I rebook?

Under the Budget coupon terms quoted on this page — again, an illustration of coupon conditions rather than a live offer, because the terms say "Rental must begin on or before 12/31/23" — the reservation must be cancelled by the rental date or the coupon will be used, the coupon is one per rental, and it may not be used with any other coupon, promotion or offer [4]. Those terms also say coupons cannot be applied to completed rentals [4].

Do I need an account to get the best rate?

Budget's sign-in screen says login is not required to complete a reservation [4], while its member benefits terms say you create or log in to a Budget.com account to get the best rate, subject to a list of exceptions [4]. Avis lists an Avis Preferred programme [3], and Enterprise presents Enterprise Plus as rewarding repeat rentals [5].
