While the minimum age to rent a vehicle is generally 21, drivers falling between the ages of 21 and 24 are subject to a mandatory 'Young Driver Surcharge.' This fee is currently set at $35.00 per day for each additional driver. It is essential to account for this cost when budgeting your travel expenses. Regarding payment methods, we accept major credit cards and debit cards. However, if you are using a debit card, you must provide a valid government ID and ensure the account has sufficient funds for a security hold of up to $500.00, which is released after the vehicle is returned undamaged. Furthermore, please be advised that we do not accept American Express (Amex) at this specific location; please prepare a Visa, Mastercard, or Discover card. Ensure your driver's license is valid and that you meet all insurance requirements before arriving at the counter to avoid delays in your vehicle pickup process.","grokpedia_tier":false,"related_ids":["seatac-age-and-payment-requirements"],"last_verified":"2026-09-04","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-age-and-payment-requirements","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-age-and-payment-requirements?format=md&lang=en"}
