Sea–Tac was developed in the 1940s to replace Boeing Field, which had been converted to military use during World War II. A site near Bow Lake was chosen in 1942 and construction began the following year with funding from the federal government, Port of Seattle, and the City of Tacoma. The airport opened on October 31, 1944. The first scheduled commercial flights from the airport began in September 1947 and the terminal was dedicated on July 9, 1949.<ref>{{Cite web|url= https://www.portseattle.org/blog/sea-airport-then-and-now|title= SEA Airport: Then and Now|last= Swift|first= Cathy|date= July 3, 2023|website= Port of Seattle|access-date= December 21, 2024|archive-date= December 4, 2024|archive-url= https://web.archive.org/web/20241204221315/https://www.portseattle.org/blog/sea-airport-then-and-now|url-status= live}}</ref> Sea–Tac was expanded in 1961 to accommodate jetliners and added new concourses and satellite terminals by 1973. The main runway was extended several times and twinned in 1970; the third runway opened in 2008 following several decades of planning due to local opposition.{{citation needed|date=December 2024}}

Several major concourse expansions and renovations were initiated in the 2010s to accommodate passenger growth at Sea–Tac, which had become a new hub for Delta Air Lines. A new international arrivals facility opened in 2022 as part of the program. In 2023, Sea–Tac served 50,887,260 passengers, 2% below the all-time record set in 2019.<ref>{{cite web|url=https://www.portseattle.org/news/seattle-tacoma-international-airport-kicks-75th-anniversary-after-near-record-volumes-2023|title=Sea-Tac Airport Nearly Breaks All-Time Record For Passengers in 2023|website=portseattle.org|accessdate=February 17, 2024|archive-date=February 18, 2024|archive-url=https://web.archive.org/web/20240218033147/https://www.portseattle.org/news/seattle-tacoma-international-airport-kicks-75th-anniversary-after-near-record-volumes-2023|url-status=live}}</ref>

==History==

===Construction and early growth (1942–1967)===

A shared public airport was proposed by the Port of Seattle and Port of Tacoma in the late 1920s, but deferred plans after the legality of public ports operating such facilities was rejected by the state attorney general in a published opinion. The state legislature authorized municipal corporations such as public ports to establish aviation facilities in 1941.<ref>{{cite web |last=Caldbick |first=John |date=August 2, 2010 |title=Airports Owned by Washington's Public Port Districts |url=https://dev.historylink.org/File/9498 |work=HistoryLink |accessdate=July 1, 2024 |archive-date=July 2, 2024 |archive-url=https://web.archive.org/web/20240702053302/https://dev.historylink.org/File/9498 |url-status=live }}</ref> The Port of Seattle accepted a $1 million grant (equivalent to ${{Format price|{{Inflation|US-GDP|1000000|1942}}}} in {{Inflation-year|US-GDP}} dollars){{inflation-fn|US-GDP}} from the Civil Aeronautics Administration in March 1942 to construct a new airport to serve the Seattle area after the U.S. military took control of Boeing Field during World War II. A site on U.S. Route 99 near Bow Lake south of Seattle was chosen at the end of the month ahead of another candidate near Lake Sammamish that was considered too close to the Cascade Range.

The enlargement of the airport's runways was precipitated by the major augmentation of commercial air traffic in the 1950s. Larger aircraft such as the Douglas DC-6, which introduced a pressurized cabin; the DC-7; Lockheed Constellations; and Boeing 377 Stratocruisers were some of the last turboprops to fly long-distance from Seattle. By 1957, Sea-Tac hosted 400 flights per week, with United as the largest carrier, offering 260 of those. The Boeing 367-80 or Dash-80, the first aircraft to demonstrate the potential of jet aviation, was accommodated by the 1955 runway extension when it first flew into Sea-Tac on September 27, 1956. The first regular jet service to Sea-Tac was provided by Pan Am on October 3, 1959, when a Boeing 707 departed for Honolulu. In 1961 Alaska introduced Convair 880 service on its lucrative Anchorage–Seattle flights after Northwest and Pan Am had introduced the type on the same route, which reduced flying time to three hours from the eight-hour, multi-stop journey on piston-engined planes. Braniff and United introduced an interchange service between Houston and Seattle on DC-6s, where the airline crews switched on the stopover in Denver; by 1965 the DC-6s had been replaced by Boeing 720s. United, meanwhile became the first carrier to serve Sea-Tac with Douglas DC-8s when it introduced them on the routes to Chicago and Idlewild (now JFK) Airport in New York. By 1962 Northwest offered flights from Sea-Tac to six destinations, including Portland, Honolulu, Anchorage, Spokane, and Chicago, while Pan Am served Fairbanks, Honolulu and offered transatlantic service to London. Western Airlines introduced 720 service from Sea-Tac on routes to Portland, Minneapolis-St. Paul, Los Angeles, and San Francisco after acquiring Pacific Northern Airways in 1967. Jet service on 707s and its sister 720s was augmented with the addition of the three-engine Boeing 727 in the mid-1960s, which allowed passenger numbers to double at Sea-Tac during that decade. Alaska introduced these on service to Anchorage and Sitka in 1966, while Braniff International had service on the 727 to both San Antonio and Dallas in 1967, and Western introduced it on service to Seattle in 1970.<ref name="HistoryLink-Part2"/><ref name="DepartedWingsA">{{cite web |title=THE AIRPORTS: PACIFIC NORTHWEST – SEATTLE-TACOMA INTERNATIONAL AIRPORT |url=http://departedwings.com/The%20Airports/SEA/SEA.html |publisher=Departed Wings |accessdate=March 14, 2026}}</ref>

Residents of the surrounding area filed lawsuits against the Port in the early 1970s, complaining of noise, vibration, smoke, and other problems. The Port and the government of King County adopted the Sea–Tac Communities Plan in 1976 to address problems and guide future development. The Port spent more than $100 million over the next decade to buy homes and school buildings in the vicinity, and soundproof others nearby. In the mid-1980s, the airport participated in the airport noise-compatibility program initiated by Congress in 1979. Airport-noise contours were developed, real estate was purchased and some homes were retrofitted to achieve noise mitigation.<ref>C.

In 1978 the U.S. ended airline regulation, and the U.S. airlines were allowed to determine routes and fares without government approval. Deregulation resulted in some new service to Seattle, including from TWA, then the fourth-largest U.S. airline, as well as Delta, National, and American.

Shortly after the death of U.S. Senator Henry Martin "Scoop" Jackson, the Port Commission voted on September 13, 1983, to change the airport's name to the Henry M. Jackson International Airport. Citizens of Tacoma were angered by the removal of their city's name despite their contribution to the airport's original construction budget, which had come with a promise to share the name. An additional complicating factor was the existence of another Jackson International Airport (now Jackson–Medgar Wiley Evers International Airport) in Jackson, Mississippi.<ref name="Banel-Jackson">{{cite news |last=Banel |first=Feliks |date=May 26, 2023 |title=When Sea-Tac Airport disappeared for six months |url=https://mynorthwest.com/3139553/all-over-the-map-sea-tac-airport-monument-to-end-of-inter-city-war/ |publisher=KIRO-FM |accessdate=May 24, 2024 |archive-date=May 25, 2024 |archive-url=https://web.archive.org/web/20240525065657/https://mynorthwest.com/3139553/all-over-the-map-sea-tac-airport-monument-to-end-of-inter-city-war/ |url-status=live }}</ref> During the November 1983 elections, an advisory referendum in Tacoma on the airport's name endorsed the original name by a 4–1 margin and two incumbent Port commissioners were defeated by candidates in favor of restoring the Sea–Tac name.<ref name="Banel-Jackson"/><ref name="Times-Jackson">{{cite news |last=McDonough |first=Sandra |date=February 29, 1984 |title=Renaming of airport hailed as triumph for public |page=C1 |work=The Seattle Times}}</ref> Helen Jackson, the widow of the late senator, expressed her desire that their family remain neutral in the debate.<ref>{{cite news |date=February 20, 1984 |title=Airport conflict saddens Jackson's widow |page=B1 |work=The News Tribune |agency=Associated Press |url=https://www.newspapers.com/article/the-news-tribune-airport-conflict-sadden/148030468/ |via=Newspapers.com |accessdate=May 24, 2024 |archive-date=May 25, 2024 |archive-url=https://web.archive.org/web/20240525065656/https://www.newspapers.com/article/the-news-tribune-airport-conflict-sadden/148030468/ |url-status=live }}</ref> With a 3–2 vote of the Port Commission on February 28, 1984, the name reverted to Seattle–Tacoma International Airport and the four signs with Jackson's name were removed.<ref name="Times-Jackson"/><ref>{{cite news |last=Gillie |first=John |date=February 29, 1984 |title=It's Sea-Tac again, amid rejoicing |page=A1 |work=The News Tribune |url=https://www.newspapers.com/article/the-news-tribune-its-sea-tac-again-ami/148030509/ |via=Newspapers.com |accessdate=May 24, 2024}}</ref>

In the late 1980s, the Port of Seattle and a council representing local county governments considered the future of air traffic in the region and predicted that the airport could reach capacity by 2000. The rising use of regional airliners such as Horizon Air caused aircraft movements to triple from 1978 to 1990 and air cargo use at the airport had also risen dramatically.{{sfnp|Oldham|Blecha|HistoryLink Staff|2011|pp=87, 90}} In 1992, the planning committee concluded that the best solution was to add a third runway to the airport and construct a supplemental two-runway airport in one of the neighboring counties. Members of the community opposed a third runway, as did the Highline School District and the cities of Des Moines, Burien, Federal Way, Tukwila, and Normandy Park,{{sfnp|Oldham|Blecha|HistoryLink Staff|2011|p=91}} but a 1994 study concluded there were no feasible sites for an additional airport. The Port of Seattle approved a plan for the new runway in 1996, prompting a lawsuit from opponents. The Port secured the necessary permits by agreeing to noise reduction programs and environmental protections.<ref>{{cite news |last1=Lange |first1=Larry |title=State allowed to join lawsuit on 3rd runway at Sea-Tac |url=https://www.seattlepi.com/news/article/state-allowed-to-join-lawsuit-on-3rd-runway-at-1120066.php |access-date=December 18, 2023 |work=Seattle Post-Intelligencer |date=July 23, 2003 |archive-date=December 19, 2023 |archive-url=https://web.archive.org/web/20231219000025/https://www.seattlepi.com/news/article/state-allowed-to-join-lawsuit-on-3rd-runway-at-1120066.php |url-status=live }}</ref> Runway opponents appealed these permits, but dropped their challenges in 2004.<ref>{{cite web |last=Wilma |first=David |date=September 16, 2004 |title=Airport Communities Coalition drops opposition to Sea-Tac International Airport third runway on August 19, 2004. |url=https://www.historylink.org/File/5733 |work=HistoryLink |access-date=December 18, 2023 |archive-date=December 19, 2023 |archive-url=https://web.archive.org/web/20231219000026/https://www.historylink.org/File/5733 |url-status=live }}</ref>

===Modernization and expansion (2008–present)===

The airport's Central Terminal building was renovated and expanded in 2003 in a project designed by Curtis W. Fentress, of Fentress Architects.{{citation needed|date=June 2024}} The renovation and expansion began in 1996 and underwent extensive modifications to accommodate new security requirements following the September 11 attacks in 2001.{{sfnp|Oldham|Blecha|HistoryLink Staff|2011|p=100}}

In 2014, Delta Air Lines announced plans to expand Seattle into a transpacific hub. Since then, Delta has added numerous international flights and dozens of domestic flights to feed those services. Delta's increased presence in Seattle has been seen by some industry analysts as a response to United Airlines' transpacific hub at San Francisco, as well as Delta's disenchantment with its former Tokyo–Narita hub.<ref>{{Cite news |last=Carey |first=Susan |date=June 29, 2014 |title=Delta, Alaska Airlines Go to War Over Seattle |work=The Wall Street Journal |url=https://online.wsj.com/articles/delta-alaska-airlines-go-to-war-over-seattle-1404076082 |url-status=live |access-date=November 19, 2014 |archive-url=https://web.archive.org/web/20141022094244/http://online.wsj.com/articles/delta-alaska-airlines-go-to-war-over-seattle-1404076082 |archive-date=October 22, 2014}}</ref>

The airport's original control tower, built in the 1950s, is now part of the passenger terminal and used as a ramp control tower after being repaired from damage caused by the 2001 Nisqually earthquake.

A recurring problem at the airport is the misidentification of the westernmost taxiway, Taxiway Tango, as a runway.

In 2007, the airport became the first to implement an avian radar system providing 24-hour monitoring of wildlife activity across the airfield. This pilot program, designed and implemented with the assistance of the University of Illinois Center of Excellence for Airport Technology (CEAT), was intended to decrease potentially fatal incidents involving collisions with birds and to provide a test bed for the implementation of the technology in the United States, which was expected to begin in 2009. The technology is part of a strategy to reduce the presence of wildlife on the airfield.<ref>{{cite web |title=Wildlife Management |url=https://www.portseattle.org/Environmental/Water-Wetlands-Wildlife/Pages/Wildlife-Management.aspx |url-status=dead |archive-url=https://web.archive.org/web/20120514184311/http://www.portseattle.org/Environmental/Water-Wetlands-Wildlife/Pages/Wildlife-Management.aspx |archive-date=May 14, 2012 |access-date=July 3, 2012 |website=Port of Seattle}}</ref>
