March 12, 2026 — San Francisco Travel industry news outlets reported San Francisco International Airport (SFO) Chaos on March 12, 2026: 107 Flight Disruptions Amid DHS Shutdown Day 28 and TSA Staffing Crisis at San Francisco International Airport, where 96 flights were delayed and 11 canceled, affecting approximately 16,050 passengers across airlines including United Airlines, Delta, American Airlines, Southwest, Alaska, British Airways, Japan Airlines and All Nippon Airways.
The disruptions impacted domestic routes to Los Angeles (LAX), Seattle (SEA) and Chicago (ORD), as well as transpacific flights to Tokyo, transatlantic and Latin American destinations, according to TravelTourister and Travel and Tour World.
Causes of Disruptions
Reports attributed the San Francisco International Airport (SFO) Chaos on March 12, 2026: 107 Flight Disruptions Amid DHS Shutdown Day 28 and TSA Staffing Crisis primarily to nationwide weather and storms, compounded by indirect effects from day 28 of the partial Department of Homeland Security (DHS) shutdown that began February 14. The shutdown has left 50,000 TSA agents unpaid, resulting in doubled absences of 7-8% and around 300 resignations, per CBS News.
TSA staffing strains caused security lines up to three hours at airports including Houston Hobby and New Orleans, with warnings of worsening after the March 14 paycheck deadline. SFO experienced milder effects due to private screeners, as noted in LA Times.
Official Statements and Blame
DHS officials blamed congressional Democrats for the shutdown, according to TravelTourister and a White House article. TSA warned of ongoing challenges amid spring break travel surges.
Airports advise travelers to arrive 3-4 hours early amid massive delays.
