As of midday Friday, San Diego reported 27 flight cancellations, a sharp increase from just two cancellations the previous day. Travelers to and from San Diego, Los Angeles, and Ontario international airports experienced delays and cancellations due to reduced flight capacity at 40 major U.S. airports.
The flight capacity reductions stem from a federal government shutdown causing staffing shortages among air-traffic controllers. Although controllers are essential workers required to continue working without pay, the shortage has created system strain.
Department of Transportation officials described the situation as having "staffing triggers" at air traffic facilities nationwide, leading to "strain on the system."
The Federal Aviation Administration (FAA) reported 2,740 flight delays last weekend, with expectations that delays will worsen if the shutdown continues. Transportation Secretary Sean Duffy announced on Wednesday that flight capacity would be reduced at 40 high-traffic airports starting Friday.
The FAA has also limited commercial space launches and reentries to the hours after 10 p.m. Parachute operations and photographic missions near the affected airports are currently prohibited.
The ongoing federal shutdown has significantly reduced flight capacity and increased delays at major airports due to understaffed air traffic control, with stricter restrictions affecting air operations further.
