San Francisco International Airport (SFO) has opened the final section of its $2.5 billion Harvey Milk Terminal 1. 

The fourth and final phase includes a new north check-in lobby, a new mezzanine-level security checkpoint, two additional aircraft gates, four new concessions and a new connecting walkway that links all SFO terminals post-security.

The new north check-in lobby will be occupied by Alaska and Delta Airlines, and features new automated bag drop technology.

The new mezzanine-level security checkpoint, featuring automated screening lanes, will provide seamless access from the Terminal 1 AirTrain station.

“There is no better way to celebrate Pride Month at SFO than the completion of the first airport terminal in the world named for an LGBTQ leader who changed our city and our country,” said San Francisco Mayor London Breed. 

“Harvey Milk Terminal 1 serves as a welcoming beacon to travellers, showcasing the very best ideals and values of San Francisco and what we represent. My thanks go to the entire SFO team for this milestone achievement.”

SFO airport director Ivar Satero added: “Harvey Milk Terminal 1 represents a new benchmark for the airport experience at SFO. This facility was designed to be extraordinary in every way… as a place of ease and relaxation, a place of sustainable design and operation, a place of inspiring artwork and museum exhibits, and a place to share the story of pioneering civil rights leader Harvey Milk. The entire SFO family can be truly proud of creating something that will serve our region for decades to come.”
