Ensure your airline mileage plan allows you to convert air miles to car rentals. If it is allowable, calculate your air miles.
Airlines that allow conversion to car rentals, lodging or other travel services generally apply a dollar amount to each air mile. If you want your car rental completely paid for with air miles, make sure you have enough banked to cover the cost.
When you book your car rental, provide the name that appears on your airline mileage plan account or card and the membership number.
Keep your airline mileage membership number handy when you pick up your car in case the information did not carry over from the reservation.
