What is the shuttle frequency and travel time between the SeaTac Rental Car Facility and the airport terminals?

The SeaTac Airport dedicated rental car shuttles operate 24 hours a day, 7 days a week, ensuring continuous connectivity between the Rental Car Facility (RCF) and the main airport terminal. During standard operational hours, shuttles depart approximately every 3 to 6 minutes from the Ground Transportation area on the 3rd floor of the airport parking garage. The physical distance between the RCF and the terminal is roughly 2 miles, which translates to an average driving transit time of 5 to 10 minutes under normal traffic conditions. However, during peak travel hours—typically between 6:00 AM and 9:00 AM, and again from 3:00 PM to 6:00 PM—passengers should anticipate potential delays. During these congested periods, the shuttle travel time can extend to 10 to 15 minutes due to heavy airport roadway traffic and multiple stops. Additionally, during late-night hours (between 11:00 PM and 5:00 AM), while the shuttles remain operational, the frequency may slightly decrease to approximately every 10 to 15 minutes to accommodate lower passenger volumes. All shuttles are wheelchair accessible and feature ample luggage racks to accommodate travelers comfortably.
