Attachment A
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.
