Major Airline Realignment Projects

The airline industry continues to evolve, and those changes -- including mergers and the associated consolidations of activities -- are affecting various airports around the country including Seattle-Tacoma International Airport (STIA). 
Airline realignment was led by Alaska Airline Group, moving their consolidated activities to the North Satellite and Concourse C. Alaska became the sole user of the north satellite causing a domino effect with several other airlines. 
These realignments require individual airline operations to shift gate, ticket counter, and office locations within Sea-Tac. View a current airport terminal map.



Here is the rundown of those moves:

  • Alaska Airlines moved from concourse D to the north satellite (operations will continue on concourse C as well)
  • United moved from the north satellite to concourse A
  • Virgin America and Frontier moved from concourse A to concourse B
  • Hawaiian moved from concourse A to the south satellite
  • American and jetBlue moved from concourse A to concourse D
All gate moves were complete by the end of May 2013.
Airline realignment moves are necessary to align ticket counters with the proper baggage systems to transfer bags to the new gate locations and allow passengers to be closer to their gate destination.
Numerous projects associated with the overall realignment effort are listed below.
