of air traffic out of proportion to its size. , 31 airlines operate at SEA, serving 91 domestic and 28 international destinations. Art collection As part of the 1973 expansion of the facilities at Sea-Tac, the Port commissioned US$300,000 of original art. The first such purchase by a U.S. airport, these works were the start of an extensive art collection owned by the Port, on display in both public areas and office spaces of various Port facilities. In recent years () the Port has emphasized acquiring works by women, people of color, LGBTQ+ artists, and (especially) indigenous artists. Of 111 pieces in the airport collection as of 2021, 35 were by artists of color and 54 by female artists. Another recent initiative is to focus a significant portion of the Port's art budget on conservation of works already owned by the Port. In 2112, the Port began a related program of musical performances at the airport by local musicians. At the time the COVID-19 pandemic temporarily shut down this initiative in 2020, 115 different performers and groups had participated. In 2018 alone, ther were 1,452 musical performances at Sea-Tac.
