- Cost: $3.25 for an adult one-way ticket from Sea-Tac to ID/C.
- Payment: Use an ORCA card (recommended), the Transit Go Ticket app, or purchase a ticket at the station's vending machine.
- Transfer to a Renton-Bound Bus: At ID/C Station, exit and walk to the nearby bus bay. Key routes to Renton:

6. Traveler Tips & Local Experience
🗺️ Navigating the Transfer at International District/Chinatown
The station can be busy. Use the King County Metro Trip Planner or Google Maps for real-time bus departure info from the specific bay (e.g., Bay 4). Signs are clear, but allow 5-10 minutes for the transfer.
🧳 Managing Large Luggage
If you have multiple or oversized bags, public transit becomes challenging. Tip: Consider taking a taxi/rideshare just from the airport to the Light Rail station (a short, cheaper ride), then completing your journey on transit. Alternatively, some hotels offer baggage holding if you arrive early.
⏰ Timing Your Trip
Rush Hour Warning (Weekdays 7-9 AM & 4-6 PM): I-405 traffic can double taxi/rideshare travel times and cost. The Light Rail is unaffected by road traffic, making it a surprisingly more reliable choice during these windows.
📱 Essential Apps
- Uber / Lyft: For rideshare.
- Transit Go Ticket App / ORCA Card App: For public transit payment and management.
- OneBusAway: For real-time bus arrivals at your stop in Renton.
- Waze or Google Maps: For driving directions and live traffic.
