Frequently asked questions
Do I need the rental company's insurance?
Not always — many credit cards include collision damage waiver for rentals paid in full on the card, and travel policies often cover excess reimbursement for far less.
Why is renting at the airport dearer?
Airport locations add a concession recovery fee, typically 10–13%, on top of local taxes. Off-airport branches are usually cheaper even after a taxi ride.
What do I need to enter into the Rental Car Total Cost Calculator?
