Upcoming Plans for Seattle Airports

The Seattle-Tacoma International Airport (SEA) has been working on a Sustainable Airport Master Plan (SAMP) to meet the increasing demand for passenger and cargo services. This plan outlines necessary changes to the current facilities, infrastructure, and operations, with projections for the next five, 10, and 20 years.

As part of the SAMP, the airport has initiated a series of capital projects called Upgrade SEA. These projects aim to enhance the passengers’ experience from arriving at the airport to their departure. Recently completed projects include improvements to the Central Terminal, N Concourse, and the International Arrivals Facility, which have created or modernized approximately 1 million square feet of space.

Seattle is considering the need for a new airport due to the ongoing expansion of the Seattle-Tacoma International Airport (Sea-Tac) and the projected doubling of demand for cargo and passenger movement by air by 2050. According to an initial analysis by the Washington State Department of Transportation (WSDOT), there are 10 possible locations for the new airport.

However, no one wants the new airport near them, and local communities do not necessarily favor it being built in their backyard. The Sustainable Airport Master Plan (SAMP) by the Port of Seattle recommends more than 30 near-term projects, including a new terminal with 19 gates and an automated people mover with three stations to connect the rental car facility, new terminal, and main terminal at Sea-Tac.

While a recommendation for a major new airport was expected to come by 2022, there is no indication in the search results that this has been finalized.
