What you'll find at Seattle-Tacoma International Airport
Seattle-Tacoma International Airport, known as Sea-Tac, sits about 14 miles south of downtown Seattle and serves the Seattle and Tacoma metropolitan areas. The airport has one main terminal building divided into three concourses — North, Central, and South — where all commercial flights operate.

The airport handles roughly 50 million passengers per year across more than 80 airlines. Sea-Tac is a hub for Alaska Airlines and also serves major carriers including American, Delta, Southwest, and United. The terminal includes restaurants, retail shops, and services like currency exchange, though prices are higher than outside the airport.

Getting to and from the airport by light rail
The Link light rail line runs from Sea-Tac to downtown Seattle, with stops at the University of Washington, Capitol Hill, and Westlake Center. The trip from the airport to downtown takes about 40 minutes. Trains run every 6 to 15 minutes during peak hours and every 15 to 30 minutes during off-peak times. The light rail station is located below the main terminal building and is accessible by elevator or stairs.
A one-way ticket costs $3.25 for adults during off-peak hours and $3.50 during peak hours (weekday mornings and evenings). Children ages 6 to 18 pay a reduced fare, and children under 6 ride free. You can buy tickets at machines in the station or through the Orca card, which is a reloadable transit card used across King County public transportation. If you plan to use public transit multiple times during your stay, an Orca card may save money compared to buying individual tickets.
Parking options and rates at Sea-Tac
The airport operates four parking facilities: Economy Parking, Garage Parking, Premium Parking, and Valet Parking. Economy Parking is the least expensive option at $15 per day and is located in a surface lot about a 10-minute walk or free shuttle ride from the terminal. Garage Parking costs $22 per day and offers covered spaces closer to the terminal. Premium Parking runs $35 per day and provides the closest covered spots with direct access to the terminal.
Valet Parking costs $40 per day and handles parking for you; you drop your car at the terminal entrance and an attendant parks it. All rates are for 24-hour periods, and rates increase for longer stays. The airport offers discounts if you purchase parking in advance through its website — advance Economy Parking can cost as low as $12 per day depending on the dates. Monthly rates are also available for frequent travelers.
If you are staying longer than a week, off-airport parking lots near Sea-Tac often charge $8 to $12 per day and provide shuttle service to the terminal. These lots are not operated by the airport but by private companies and may offer better rates for extended stays.
Ride-sharing, taxis, and shuttle services
Uber and Lyft pickups occur on the third level of the terminal in a designated ride-sharing zone. You request your ride through the app, and the driver meets you in the designated area. Prices vary based on demand and time of day; expect to pay $20 to $40 for a trip to downtown Seattle during normal conditions, though surge pricing can increase fares significantly during peak travel times.
Taxis are available on the second level of the terminal in a separate taxi queue. You join the line and are assigned a cab by the dispatcher. Taxi fares to downtown Seattle typically run $40 to $50 plus tip. Unlike ride-sharing, taxi fares are metered and regulated by the city, so the price does not change based on demand.
Shuttle services, including hotel shuttles and shared-ride shuttles, operate from the ground level of the terminal. If your hotel offers a free shuttle, you can find the shuttle stop by asking at the information desk or checking your hotel's website before arrival. Shared-ride shuttles that serve multiple hotels charge $18 to $25 per person to downtown Seattle and make multiple stops.
Moving through the terminal and security screening
The main terminal has three concourses connected by a central hub. Domestic flights typically depart from the North and Central concourses, while international flights use the Central and South concourses. Check your airline's website or your boarding pass to confirm which concourse your flight uses, as walking between concourses can add 10 to 15 minutes to your journey.
Security screening happens in the central hub area. Standard screening lines move at varying speeds depending on time of day; early morning and late evening tend to be busier. If you have TSA PreCheck, you can use a dedicated PreCheck lane that typically has shorter wait times. Clear, a separate program that uses biometric scanning, allows you to skip the line entirely if you are enrolled. Both programs require advance enrollment and payment of an annual fee.
The airport recommends arriving two hours before a domestic flight and three hours before an international flight to allow time for parking or ground transportation, checking bags, and passing through security.
Dining, shopping, and airport services
The terminal has restaurants and cafes throughout all three concourses, including local Seattle businesses like Beecher's Cheese and Piroshky Piroshky alongside national chains. Prices are higher than outside the airport; a sandwich or salad typically costs $14 to $18. If you want to save money, you can bring your own food through security in a carry-on bag.
Retail shops include bookstores, electronics, duty-free shops, and clothing stores. A currency exchange service operates in the international arrivals area for passengers arriving from abroad. ATMs are located throughout the terminal and charge standard out-of-network fees if your bank is not represented.
Free Wi-Fi is available throughout the terminal. Charging stations for phones and laptops are located in seating areas and near gates. If you need to shower or rest between flights, the airport does not operate a dedicated shower facility, but some airport hotels offer day-use rooms for a few hours.
Baggage handling and checked luggage
Each airline sets its own baggage policies regarding the number of bags you can check and carry on, as well as size and weight limits. Most airlines allow one free checked bag for domestic flights and two for international flights, though budget airlines may charge for checked bags. Check your airline's website before you arrive to understand what you can bring.
If you need to check a bag after you have already passed through security, or if you are picking up a bag that was checked through to a connecting flight, baggage services are located in the baggage claim area on the ground level. Baggage storage is not available at Sea-Tac, but some off-airport storage facilities in the Seattle area offer short-term storage if you need to leave luggage between flights or during your stay.
