The busiest airport in the Northwest Pacific, SEA Airport, has completed a $546 million gateway project. Airport leaders celebrated the completion of the monumental project after two years of construction. The officials also noted the aim of the gateway project is to improve infrastructure and help travelers move through security faster. The renovation gives the airport’s North Main Terminal a significant makeover, marking the completion of SEA Gateway.

Delivery on the project was done by a partnership between the Port of Seattle and Alaska Airlines. Its completion highlights a fresh, modern front door for the airport while streamlining the check-in process for travelers. “It is a product that we really looked at from the curb, all the way through the checkpoint and to the gates. That is really about customer service and friendliness and flow through,” said Wendy Reiter, SEA Airport Managing Editor. Airport terminal renovations are becoming fundamental as other airports such as Pittsburgh International Airport also upgrade their terminals. 

Outlook on the SEA Airport Gateway Project

The SEA Airport Gateway project adds more than 24,000 square feet of new office and counter space on the bridge level. Changes were also specifically designed to improve the check-in experience for Alaska Airlines passengers. “When they arrive at the airport, they have access to fast self-serve bag tagging and drop options,” said Charu Jain. Mr. Jain is the Senior Vice President of Merchandising and Innovation at Alaska Airlines.

Furthermore, he noted that passengers can use the airports IPad-based bag tag stations to get their tags. This facilitates seamless services as the passengers can use the automated bag drops to drop their bags and validate their ID. Looking ahead, airport leaders said this project kicks off a year of upgrades at SEA Airport. Work is expected to wrap up before the FIFA World Cup arrives later this year.

“We’re on track to wrap up roadway improvements and the opening of the C concourse expansion project,” said Ryan Calkins, Port of Seattle Commission President. “This means that lanes are clearing and walls are finally coming down, something we know passengers are excited about.”
