## What to know

When renting a vehicle at the Seattle-Tacoma International Airport rental car facility, customers are required to provide a security deposit to cover potential costs such as fuel charges, traffic violations, or damages. The security deposit amount ranges from $300 to $500, depending on the vehicle category and the renter's credit history status. We strongly recommend using a major credit card for this transaction, as the deposit is processed as a pre-authorization which does not immediately deduct from your balance. If you choose to use a debit card, additional requirements may apply, including the presentation of a return flight itinerary and a minimum balance requirement in the account. Please note that once the vehicle is returned in good condition, the pre-authorization is released, but it may take 3 to 10 business days for your bank to reflect this in your statement. Ensure your card has sufficient credit limit to cover both the rental rate and the security deposit.
