Causes

Unpredictable weather has been a major cause of disruptions

Unpredictable weather has been a major cause of the disruptions, with thunderstorms, strong winds and low visibility affecting flight schedules. Congestion at key airports like O'Hare International Airport is also putting pressure on airport capacity. Airlines are facing operational challenges such as tight aircraft rotations and crew availability issues which further complicate matters.

Impact

Passengers are advised to check flight status frequently

The interconnected nature of air travel means that a delay in one hub can have a cascading effect on other cities. Passengers are advised to check flight status frequently and arrive early at airports amid the disruptions. With summer travel approaching, authorities are working to stabilize operations but delays are expected to continue in the near term.
