{"version":"2.6","id":"seatac-under-25-rental-surcharges","question":"What are the minimum rental age and fees for drivers under 25 at SeaTac Airport?","answer":"The minimum rental age is 21, and drivers aged 21-24 incur a daily young driver surcharge.","answer_detail":"At the Seattle-Tac International Airport rental car facility, the minimum age to rent a vehicle is 21 years old. However, drivers who are between the ages of 21 and 24 are classified as 'young drivers' due to insurance risk profiles associated with this demographic. Consequently, all rental agencies apply a mandatory young driver surcharge. This fee typically ranges from $25.00 to $35.00 per day, depending on the specific vehicle category and the rental company policy. It is also important to note that certain vehicle classes, such as luxury cars, large SUVs, or vans, may be strictly prohibited for drivers under 25 or may carry significantly higher fees. All drivers must present a valid driver's license and a credit card in their own name at the time of rental. We strongly recommend verifying the specific daily surcharge rate and vehicle availability directly with your chosen rental provider before completing your reservation to avoid any unexpected costs upon arrival at the SeaTac facility.","grokpedia_tier":false,"related_ids":["seatac-under-25-rental-surcharges"],"last_verified":"2026-09-11","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-under-25-rental-surcharges","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-under-25-rental-surcharges?format=md&lang=en"}
