In one of the last and largest moves in a terminal and gate realignment that began early this year at Sea-Tac Airport, United Airlines next week will move its ticket counter from the far north end of the terminal to the south end and move its gates from the North Satellite to Concourse A.
The move will enable the airport’s most popular airline, Alaska, to concentrate most of its gates in the North Satellite terminal. Some Alaska flights will continue to depart from the C Concourse, and others will use D Concourse gates, but the airline’s use of that concourse will be greatly diminished.
Alaska and its regional sister airline, Horizon Air, handle more than 50 percent of Sea-Tac passengers.
United, which began operations at Sea-Tac in 1944 and which was once part of Boeing, was once the airport’s most popular carrier. It is now the airport’s third in popularity after Alaska and Delta.
The airport said new signage will direct passengers to the proper new locations.
Airlines affected by the move include Alaska, United, Air Canada, Hawaiian, American, jetBlue, Virgin America and Frontier. The final gate moves will include Virgin America and Frontier, scheduled for May 30-31.
Here is a summary of the moves:
– Alaska Airlines moves from concourse D to the north satellite (operations will continue on Concourse C as well continuing some on D),
– United and Air Canada move from the North Satellite to Concourse A,
– Hawaiian moves from Concourse A to the South Satellite,
– American and jetBlue move from Concourse A to Concourse D,
– Virgin America and Frontier move from Concourse A to Concourse B (scheduled for May 30-31).
