Serving the capital of the United States and nearby areas, SIXT at Washington Dulles International Airport can get you to your adventure or meeting in a vehicle that fits your needs. To move around bustling roads, rent an agile sedan. If you plan to explore outside the city with your car rental, opt for an SUV. Whether with an economy, luxury or compact car or roomy SUV, we help you rent a car at IAD that can carry your cargo. To help along the way, choose an add-on for your IAD car rental, such as an additional driver, GPS, child seats and Express Toll Unlimited.
