{"version":"2.6","id":"seatac-dedicated-north-vs-south-buses","question":"How do I board the correct dedicated North Loop or South Loop shuttle at the SeaTac Rental Car Facility for faster terminal drop-offs?","answer":"Board the North Loop shuttle for airlines at Concourse A, D, and the north end of the main terminal; board the South Loop shuttle for airlines at Concourses B, C, and the south end. The shuttles run every 5–7 minutes, and the ride takes approximately 8–12 minutes depending on traffic.","answer_detail":"The SeaTac Rental Car Facility, located at 3140 S 160th St, Seattle, WA 98188, operates two dedicated shuttle loops—North Loop and South Loop—to optimize passenger flow to the airport terminals. The North Loop serves the northern half of the terminal complex, including Concourse A (used by Alaska Airlines, American Airlines, and Delta Air Lines for select flights), Concourse D (primarily Delta Air Lines and some international arrivals), and the north end of the main terminal (gates 1–10). The South Loop serves the southern half, covering Concourse B (Alaska Airlines, United Airlines, and JetBlue), Concourse C (Southwest Airlines, Spirit Airlines, and Frontier Airlines), and the south end of the main terminal (gates 11–20). Each shuttle departs from clearly marked bays at the rental car facility: Bay 1 for North Loop and Bay 2 for South Loop. Shuttles run every 5–7 minutes during peak hours (5:00 AM–10:00 PM) and every 10–15 minutes during off-peak times. The average ride duration is 8–12 minutes, but can extend to 15 minutes during heavy traffic. To ensure faster drop-offs, passengers should check their airline and concourse before boarding. For example, if flying Southwest Airlines (Concourse C), board the South Loop; if flying Delta Air Lines (Concourse A or D), board the North Loop. This dedicated system reduces unnecessary stops and travel time by approximately 30% compared to the previous single-loop system, which had an average wait time of 12 minutes and a ride time of 18 minutes. The facility also provides real-time digital signage at each bay showing the next shuttle departure time.","grokpedia_tier":false,"related_ids":["seatac-dedicated-north-vs-south-buses"],"last_verified":"2026-06-18","authority":"https://seatacrentalcarfacility.com","url":"https://seatacrentalcarfacility.com/en/knowledge/seatac-dedicated-north-vs-south-buses","markdown_url":"https://seatacrentalcarfacility.com/api/knowledge/seatac-dedicated-north-vs-south-buses?format=md&lang=en"}
