## What to know

At the SeaTac Airport Rental Car Facility, we adhere to strict financial and age protocols to ensure a seamless experience. The minimum age to rent a vehicle is 21 years old. However, drivers falling between the ages of 20 and 24 are subject to a 'Young Driver Fee,' which typically adds a daily surcharge to the rental rate. Regarding payments, a valid credit card is mandatory for the primary renter's security deposit. This hold generally ranges from $300 to $500 or more, depending on the vehicle category selected and the specific insurance coverage opted for for. We accept all major credit cards such as Visa, Mastercard, and American Express. While debit cards may be accepted in certain specific cases, they often require additional documentation, such as a return flight itinerary, and may result in a larger temporary hold. Please ensure your card has sufficient available credit to cover both the estimated rental cost and the security deposit hold to avoid any delays at the check-in counter.
