Major expansion to handle growth planned at Sea-Tac Airport

SEATTLE — Port of Seattle commissioners are looking at a major expansion at Sea-Tac Airport to accommodate expected passenger growth over the next 20 years, starting with a new international arrivals facility in 2019.

At a meeting Tuesday, commissioners and airport officials discussed plans for the facility estimated to cost $608 million. They also talked about adding 35 more airplane gates to the current 81 gates, The Seattle Times reported.

The airport needs to prepare for a projected 66 million passengers a year two decades from now, officials said. Last year, 37 million passengers passed through the airport. By 2034, the airport projects 540,000 takeoffs and landings per year, compared with 350,000 last year.

Airport officials laid out options for expanding the main terminal and adding gates north and south.

Alaska Airlines is currently the airport’s largest user. It carries more than half of Sea-Tac’s passengers and pays the port $115 million a year.

Delta is growing fast and aims to make Sea-Tac a major international gateway. It’s looking forward to the new International Arrivals Facility that would replace the current customs area at the south satellite terminal. The airport says it’s congested at peak times when multiple wide-body jetliners arrive.
