Seattle-Tacoma International Airport (Sea-Tac) has jumped to become the ninth busiest airport in the US. It rose to that rank from being 13th the previous year. Over 45 million passengers walked through its terminals in 2016, helping the airport continue its growth in terms of traffic.
Sea-Tac is a means for millions of visitors to come and see the sights in the Pacific Northwest. Domestic and international travelers fly into Seattle to tour the city, and many of them also use Seattle as a home base when visiting British Columbia or areas in Oregon. Direct flights connect the region with major international cities, and non-stop service is now available to both Guadalajara, Mexico and Shenzhen, China.
To keep up with the growth, officials are planning multi-million dollar expansions to the terminals. They hope to add more gates and possibly a new terminal since airplane traffic is constrained by the physical layout of the airport itself.
Airlines that serve Sea-Tac are expected to contribute to the airport development. Funding may also come from tax revenue and other fees. Just how that money will be allocated, though, remains to be seen. Both the domestic and international terminals will likely receive upgrades, and airlines are all clamoring for enhanced renovations to be conducted in the areas where their customers are served.
As of this point, a new International Arrivals Facility is on the books for 2019, and more projects are on the horizon.
