Why Flights In America Are Being Cancelled and Delayed

Flight disruptions across the USA can result from several operational factors working at the same time. Weather conditions such as thunderstorms and strong winds can affect departures, arrivals, runway use, and aircraft movement. Traffic-management measures may also be introduced when demand places additional pressure on available capacity.

Airport infrastructure work can create another source of delays, particularly when runway availability is reduced. Aircraft rotations, crew availability, air-traffic management, gate capacity, and other operational requirements can also influence schedules.

These factors can affect an individual flight even when conditions at its departure airport appear manageable, because aircraft and crews may arrive from another location experiencing disruption.
