Operational Factors Behind Flight Cancellations In The United States

Flight cancellations across the United States can result from a combination of operational challenges affecting airlines and airports.

Aircraft availability, runway work, airport capacity, crew scheduling, air-traffic conditions, weather, and unexpected equipment issues can all influence flight schedules.
