Airline Realignment

The airline industry continues to evolve and those changes are affecting Seattle Tacoma International

Airport (STIA). Those changes include mergers and the associated consolidations of activities at various

airports around the country including STIA. Delta Airlines has merged with the former Northwest

Airlines and their consolidated activities will take place primarily at the South Satellite. United Airlines

is merging with Continental Airlines and their consolidated activities will be realigned to occur on

Concourse A. Southwest Airlines’ purchase of AirTran Airlines will merge their activities and realign on

Concourse B. In addition Alaska and Horizon Airlines have merged closer under the Alaska brand and

their consolidated activities will primarily occur at the North Satellite and Concourse C. These significant

realignments also necessitate other individual airline operations to shift gate, ticket counter, and office

locations within STIA. There are numerous projects, both directly and indirectly, associated with the

overall realignment effort, and they are listed below.
