## What to know

When renting a car at SeaTac, it's essential to understand the insurance requirements, collision damage waivers (CDW), and fuel policies. Most rental car companies require customers to have liability insurance, which typically covers damages to other vehicles or property. Some companies, like Enterprise and National, bundle CDW with their rental rates, while others, such as Hertz and Avis, offer it as an optional upgrade for an additional $15-$30 per day. Fuel policies vary, with some companies offering a 'full-to-full' policy, where you pay for a full tank upfront and return the car with a full tank to avoid refueling fees. For example, Alamo's 'Fair Fuel Policy' charges $4. 38 per gallon if you don't return the car with a full tank. On average, rental cars at SeaTac consume around 12-15 gallons of fuel per rental. Understanding these policies can help you save up to $50-$100 per rental, depending on the company and your usage.
