## What to know

Renters at the Sea-Tac International Airport (SEA) rental car facility must adhere to specific financial and age policies. A security deposit hold is mandatory on a major credit card, typically ranging from $300 for economy vehicles to up to $5,000 for luxury models or high-end SUVs. This hold is released only after the vehicle is returned in good condition and all charges are processed. For drivers between the ages of 20 and 24, a 'Young Driver Fee' is applied daily, which can range from $25 to $50 per day depending on the vehicle class and rental provider. Furthermore, international visitors must present a valid home-country driver's license accompanied by an International Driving Permit (IDP) if their native license is not written in English. Debit card users are sometimes accepted but often require proof of return flight and may result in a larger hold on the bank balance. Failure to meet these documentation requirements may result in a denial of service or significant additional surcharges at the counter.
