If you're booking online, read the terms and conditions carefully before confirming your reservation. If you're booking over the phone, ask the agent about restrictions. If pertinent, ask about any restrictions on interstate travel. For your own protection in case of breakdown, be sure the company has offices in all the states on your itinerary. Always get a confirmation number. For airport rentals, be sure to give the customer service representative your flight number and scheduled arrival time. This will usually protect your reservation if the flight is delayed.
Buyer beware: The rate you see advertised in big print may become so inflated with state and local taxes, airport surcharges, additional driver fees, insurance, gasoline bills and drop-off charges that you end up paying more than double what you expected. Learn more about these extra charges in
