How to rent a car while traveling

Book through an aggregator

Compare an aggregator with the rental company directly using the same dates, vehicle class, mileage, deposit and insurance terms. A lower headline price is not necessarily a lower total cost.

Pay attention to the supplier rating: a “great price” from a 5/10-rated local agency at airport pickup will cost you the saving in waiting time and dispute risk.

Check insurance before accepting or declining

Read the included cover, exclusions, excess and deposit. Do not decline cover solely because a card or another policy may include insurance: ask the provider to confirm the vehicle, country, drivers and rental duration are covered.

An excess-reimbursement policy is not the same as reducing the rental company’s excess. You may still have to pay first and make a claim with supporting documents. Compare the actual contracts.

Inspect, photograph, sign

Inspect and photograph the car before leaving, including wheels and interior. Ask the company to record existing damage and retain the signed condition report. Evidence can help with a dispute; it does not guarantee avoiding one.

Refuel before returning

A "full-to-full" fuel policy is the cheapest. Always return the car with the same fuel level you got it - the convenience refuel option at the counter is billed at 2–3× the pump price.
