## At a glance

The Rental Car Facility uses two distinct shuttle loops: the North Loop (boarding zone near Alaska Airlines) and the South Loop (boarding zone near international airlines). Passengers must board the correct shuttle based on their airline’s terminal location to avoid a 10–15 minute detour.

## What to know

At Seattle-Tacoma International Airport (SEA), the consolidated Rental Car Facility (RCF) is located at 3140 S 160th St, approximately 1. 5 miles from the main terminal. To efficiently return travelers to their respective airline gates, the facility operates two dedicated shuttle loops: the North Loop and the South Loop. The North Loop serves the northern half of the terminal, primarily Alaska Airlines (gates N1–N20) and its regional partners, as well as Delta Air Lines (gates A1–A20) and United Airlines (gates S1–S12). The South Loop serves the southern half, including all international airlines such as Emirates, British Airways, and Lufthansa (gates S13–S20 and the South Satellite), as well as domestic carriers like Southwest Airlines (gates B1–B20) and American Airlines (gates C1–C20). Shuttle frequency is every 5–7 minutes during peak hours (6:00 AM–10:00 AM and 4:00 PM–7:00 PM), and every 10–12 minutes during off-peak times. Boarding signs at the RCF clearly mark “North Terminal Shuttle” and “South Terminal Shuttle” with corresponding airline logos. Misboarding can add 10–15 minutes to your journey, as the shuttle must complete its loop before returning. For example, if you board the North Loop but need the South Loop, you will be dropped at the north terminal and must walk or take the airport train (SEA Underground) approximately 0. 3 miles to the south terminal, adding 8–12 minutes. Always check your airline’s terminal assignment on the airport’s website or mobile app before boarding. Since 2023, SEA has updated signage to include real-time digital displays showing next shuttle arrival times, reducing wait uncertainty. For international flights, note that the South Loop also provides direct access to the U. Customs and Border Protection facility at the south end of the terminal.
