San Francisco International Airport has cut 90 minutes of daily announcements, a move that reshapes the terminal experience. By restricting gate calls to individual gates and syncing with airlines, the airport has slashed overlapping PA chatter.

The initiative, pushed forward during the pandemic, mirrors a quieter model first adopted by United Airlines at SFO in 2018. Travelers report reduced stress, especially those with sensory sensitivities, as mobile alerts now carry most flight updates.

With noise from escalators and moving walkways next on the agenda, SFO aims to keep the terminal a calm zone. The change shows how targeted acoustic design can improve travel comfort without sacrificing safety or information flow.
