## What to know

When renting a vehicle at the SeaTac Airport Rental Car Facility, customers must adhere to specific financial and age protocols. The primary requirement for security is a valid major credit card (Visa, Mastercard, American Express, or Discover). While some locations accept debit cards for the final payment, they often require a larger hold and proof of a return flight. The standard security deposit typically ranges from $200 to $500, depending on the vehicle category and insurance coverage selected. Regarding age, the minimum age to rent is 21 years old. However, drivers aged 21 to 24 are subject to a 'Young Driver Surcharge,' which can cost approximately $30.00 per day. Upon returning the vehicle in good condition, the deposit is released within 3 to 10 business days, depending on the issuing bank's processing time. Ensure your credit limit has sufficient headroom to cover the hold to avoid delays at the rental counter.
