Operational Factors Behind Flight Cancellations Across the USA

Flight cancellations across the USA can result from a combination of operational challenges affecting airlines and airports. These can include aircraft availability, runway activity, air-traffic management measures, weather conditions, airport congestion, crew scheduling, and other factors affecting the movement of aircraft.

The FAA’s airport advisories show how individual operational issues can influence passenger schedules. Runway construction is affecting departures at San Francisco, while a disabled aircraft on the runway is affecting operations at Miami. At Harry Reid, traffic-management initiatives and weather are contributing to departure delays, while Boston is experiencing significant ground-delay impacts.
