Seattle Airport Guide 2022

Seattle Tacoma International Airport is an international airport which is the primary commercial airport that serves the Seattle Metropolitan Area in the United States. The airport is located in the city of Sea-Tac, which is approximately 23 kilometers north northeast of Downtown Tacoma. Seattle Tacoma International airport is the largest airport in the Pacific Northwest region of North America. The airport is owned by the Port of Seattle which also is also responsible for its operations.

The airport has flights that serve cities like North America, Europe, the Middle East, and Asia and is the primary hub for Alaska Airline whose headquarters are near the airport. 

The airport was built in 1944 by the Port of Seattle after the takeover by the military to control Boeing Field in World War II. The city of Tacoma provided the port with $100,000 and the Civil Aeronautics Administration provided $1 million to build the airport. In 1951 there were four runways 45 degrees angled, between 5,000 and 6,100 feet long. In 1962 the runway 34 was expanded and extended and required the construction of an automobile tunnel for South 188th street which was officially opened in July 196. Later in the year 1970, Runway 34L replaced runway 2.

There was a two-Storey North concourse which was later dubbed as concourse D, which was added four gate positions, and a new wing was extended. The one-Storey was constructed and had 8 gates. Its construction extended the airport by 688 feet. The concourse was later dubbed the current concourse A.

Between 1967 -1973, the port embarked on major expansion which included adding a second runway, a parking garage, and two satellite terminals which were planned and designed by Richardson Associates. The two satellite terminals were opened in 1973 alongside an underground train system that connected to the main terminal.

In 1970 the residents filed complaints that led to the formulation of airline regulation to curb the complaints of the residents which included noise, vibration smoke, and other problems. The regulations were ended in 1978 and airlines were allowed to determine routes and fares without government approvals.

With projected increased passenger traffic, the third runway was opened in 2008 November to allow landings in times of visibility, the runway was parallel to the existing two and therefore allowed landing in both of them.

Seattle Tacoma International Airport Future Development

With the nationwide expansion of Seattle-based Alaska Airline and Delta t Lines setting up a major international hub at Sea-Tac Airport, it has seen the airport recording growth in passenger traffic over the few years. This growth, therefore, imposes strain in the facilities at the airport. This has pushed the port into investing more than 2 billion into several expansion projects and renovations.

D gates hardstand terminal

There is a projected development that will see an additional six new gates where passengers will wait until boarding time then it will board a large bus outside of the terminal that will transport them to an aircraft parked in a remote area of the airport called a hardstand. The building will connect to the D concourse where there will be a bridge connecting them to the satellite Transit System.

Baggage system

The Port of Seattle has looked into updating the baggage handling system of the airport. The project is aimed to create one unified, high-speed baggage system under the airport.

The upgrade will increase capacity by nearly 60 percent with the projected increase of passport check booths and kiosk from 30 to 80. The baggage claim carousels are part of the expansions where there will be an increase from four to seven. The new IAF will be connected to by a footbridge 900 meters long to the south satellite. With the new IAF being opened, the South Satellite will continue to be used for the arrival of international flights where there will be additional international gates in Concourse A. this will almost be double the number of gates capable of serving larger wide-body aircraft.

South satellite modernization

After completion of the New IAF, the port of Seattle will renovate the South Satellite terminal.
