Operational And Weather Factors Behind U.S. Flight Cancellations

Flight cancellations across the U.S. can occur when weather conditions affect airport capacity, aircraft movements, or air traffic management.

Airport infrastructure work can also affect schedules. Runway construction is contributing to delays at Boston Logan and San Francisco, while traffic-management measures and weather are affecting departures from Philadelphia.
