你最好再读一读contract 上的规定。根据这段文字， 要回来的可能性很小。

Hertz No-Show Fees

Prepaid rentals: No-shows are charged full price of rental if you do not cancel your reservation prior to the pick-up time. Fee is $100 if you cancel within 24 hours of pickup. Fee is $50 if you cancel more than 24 hours before pickup. Pay later rentals: No penalty for no-shows. In the event of a flight cancellation, Hertz will not charge fee as long as a flight number and airline were provided in the reservation prior to scheduled pickup.
