Air travel at San Francisco International Airport (SFO) is facing significant disruptions due to a two-hour ground delay imposed by the FAA, primarily caused by adverse weather and wind conditions. As travelers prepare for the holiday rush, this delay has led to a ripple effect, impacting 268 flights, with 19 cancellations reported, which is about 22% of the airport's total operations. Doug Yakel, a spokesperson, indicates that while the FAA sets a two-hour delay, most travelers are experiencing around 30 to 45 minutes of wait time on average, highlighting a need for awareness as conditions fluctuate.
