## At a glance

Renters must provide US full coverage insurance, pay fees for drivers under 25, provide a $45 non-refundable debit deposit, and cannot use American Express.

## What to know

To ensure a seamless experience at the SeaTac Rental Car Facility, customers must strictly adhere to specific documentation and financial protocols. First, all renters are legally required to present a valid declaration of US full coverage insurance before taking of the vehicle; if you cannot provide proof of existing domestic coverage, you may be required to purchase additional protection plans at the counter. Additionally, for drivers under the age of 25, a significant mandatory underage driver fee is applied to the daily rate due to increased risk profiles. Regarding payment, customers opting to use a debit card instead of a credit card are subject to a mandatory non-refundable deposit of $45. This deposit serves as a security measure and is not returned regardless of vehicle condition. Furthermore, it is critical to note that American Express cards are currently restricted as a primary method of payment at this specific location. We recommend having a valid physical driver's license and all necessary insurance documents ready upon arrival to avoid delays or potential denial of rental service.
