United Airlines is making some big changes at Seattle-Tacoma International Airport (SEA). The airline is relocating its entire operation to a new concourse, meaning a new lounge will be on the way as well.
The United gates will be relocated from Concourse A to Concourse B at SeaTac, and a new United Club is expected to be built in the new terminal spaces. The project first began in 2021.
The construction of United’s new home at SeaTac has been estimated at over $100 million USD. The airport authority is responsible for the move and is paying for the cost of the changes for United, according to a report by View From The Wing. The current United Club at gate A9 will be transferred to Delta Air Lines as part of the concourse changes.
