## What to know

Renting a vehicle at the SeaTac International Airport rental car facility involves specific degee-based pricing tiers for younger drivers. Generally, individuals between the ages of 18 and 24 are subject to a 'Young Renter Surcharge' of $22.00 per day. For even younger drivers, specifically those under the age of 21, the surcharge increases significantly to $25.99 per day. These fees are implemented to offset the higher risk profile associated with inexperienced drivers. However, there are critical exemptions to these policies. If a renter is an active-duty member of the armed forces or is traveling on official government orders, the young driver surcharges may be waived or reduced depending on the specific rental agreement and agency terms. All renters must possess a valid driver's license and a credit card in their name to complete the transaction. It is highly recommended to verify specific vehicle availability for these age groups prior to arrival to ensure no unexpected costs occur at the SeaTac counter.
