VIDEO: Sea-Tac Airport terminal expansion

SEATTLE — As construction to improve Sea-Tac International Airport continues, airport officials showed Friday how far along they are with the expansion and renovation of the North Satellite terminal.

It was about a year ago when ground was broken to expand gates, specifically for Alaska Airlines.

The expansion is expected to allow Alaska to operate more flights. Officials told KIRO 7 that eight new gates are being added on top of 12 that already exist.

Dining and retail space are expected to be doubled, in addition to a new Alaska rooftop lounge that will be added.

Millions are being poured into the modernization of the North Satellite, which is expected to open the first part of 2019.

The modernization of the 45-year-old north satellite terminal is projected to offer passengers better service.

Over the next four years, construction on other airport projects will also happen with $3 billion dollars of development taking place.

Other projects include a new international arrivals facility that will better help expedite passengers coming from outside the United States.

When our partners at KIRO Radio recently spoke with the Port of Seattle Commissioner, the new international arrivals facility was nearly $150 million over budget.

At that time, she blamed rising costs on potentially dangerous chemicals called PCBs that were discovered in the ground and rising construction costs.

In addition to the international arrivals facility, 10,000 more square feet of dining and shopping space will be added to the Central Terminal.
