San Francisco International Airport (SFO) is embarking on a transformative journey with the launch of its $2.6 billion Terminal 3 West Modernization project. This ambitious initiative underscores SFO’s commitment to enhancing passenger experience, safety, and sustainability.
The project, set to be completed in phases, will culminate in early 2029 with the unveiling of a renovated check-in lobby at the eastern end of Terminal 3. The Terminal 3 modernization will revamp the existing 650,000-square-foot western half of the terminal, integrating a “seismic retrofit,” expanded security checkpoints, and new passenger amenities. An additional 200,000 square feet will be added, creating space for expanded food, beverage, and retail concessions. This new section is scheduled to open in the fall of 2027, providing travelers with a more comfortable and efficient airport experience.
Key upgrades include a new, welcoming facade that enhances the curbside experience and provides more space for check-in processes. Travelers will benefit from advanced technology, including self-service bag drop stations and new security checkpoints, one of which will be located on the mezzanine level for AirTrain passengers. The upgrades will also streamline international travel with direct access to the Customs Hall in the International Terminal via a new sterile connector from the Federal Inspection Service. The project includes the construction of a six-story building that will accommodate operational office space and new airline lounges, enhancing the airport’s service offerings. The renovated western half of Terminal 3 is set to open by fall 2027, with the six-story building following in early 2028, and the updated check-in lobby ready by early 2029. To maintain smooth passenger flow during construction, a temporary walkway will be established around the project site.
SFO’s modernization efforts are deeply rooted in sustainability, with the Terminal 3 project aiming for LEED Platinum certification. The project will incorporate eco-friendly features such as daylight harvesting, displacement ventilation, on-site photovoltaic cells, and waste heat recovery. It will also use low-carbon steel and concrete, implement energy-efficient baggage handling, utilize recycled water, and prioritize health-friendly materials.
At its peak, the modernization project is expected to employ 500 to 600 workers and will likely award more than $173 million in contracts to Local Business Enterprises, highlighting SFO’s commitment to supporting the local economy. With this massive investment, San Francisco International Airport is setting a new standard for the future of air travel, focusing on passenger comfort, safety, and environmental responsibility.
