In 1966, Scandinavian Airlines inaugurated the airport's first non-stop route to mainland Europe. The Port embarked on a major expansion plan from 1967 to 1973, adding a second runway, a parking garage, two satellite terminals, and other improvements to the airport.

Numerous residents of the surrounding area filed lawsuits against the Port in the early 1970s, complaining of noise, vibration, smoke, and other problems caused by the airport. The Port, together with the government of King County

Starting 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 airport could reach capacity by 2000. The planning committee concluded in 1992 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 strongly opposed a third runway, as did the Highline School District

The runway opened on November 20, 2008, with a total construction cost of $1.1 billion.

A recurring operational problem at the airport is misidentification of the westernmost taxiway, Taxiway Tango, as a landing surface. A large "X" has been placed at the north end of the taxiway to prevent confusion, but a number of incidents of aircraft landing on the taxiway have still occurred. The FAA issued an alert notice dated from August 27, 2009, to September 24, 2009, urging airplanes about taking precautions such as REILs and other visual cues while landing from the north.

In 2007, the airport, together with the University of Illinois Center of Excellence for Airport Technology (CEAT), became the first airport to implement an avian radar system providing 24-hour monitoring of wildlife activity across the airfield. This pilot program was designed to decrease potentially fatal incidents involving avian collisions and provide a test bed for widespread implementation of the technology in the US which was expected to begin in 2009. The technology is part of a multi-pronged strategy to reduce the dangerous presence of wildlife on the airfield.

. This plan, however, ran into several problems. First, because Boeing Field is a public airport and each airline would have to have been offered equal access, this would have required more capacity than available on the airport's single runway suitable for large commercial airplanes. (Boeing Field has a parallel, smaller runway used by general-aviation airplanes.) Major renovations to the airport would have been required to alleviate this problem. While Southwest did indicate willingness to pay for upgrades to the airport, there were also problems with the transportation infrastructure around Boeing Field, which was not designed to handle traffic in and out of a major passenger airport. It eventually became clear that Southwest Airlines would not fund the necessary transportation improvements, and the plan was shot down by King County Executive Ron Sims

The existing facility is used to its full potential yet it continuous to be packed with people arriving. Plans have been made for major expansions such as adding two new baggage claims and increasing immigration inspection booths from 20 to 30. There is no certainty right now, but there is even a plan for a skybridge or tunnel over to the main terminal at Concourse A where passengers will have a new area. This is a possible solution to the double claim problem for baggages as well.
