What is a Flight Diversion?

Causes of Flight Diversions

Flight diversions can occur for various reasons, including:

Weather conditions: Adverse weather at the destination airport, such as thunderstorms, hurricanes, or fog, can lead to diversions.
Aircraft or crew issues: Technical problems with the aircraft or medical emergencies involving passengers or crew may necessitate a diversion.
Security threats: Suspicious activity or potential security threats can prompt authorities to divert flights for safety reasons.
Natural disasters: Earthquakes, volcanic eruptions, or other natural disasters can force flights to divert to nearby airports.
Airspace restrictions: Military exercises, air shows, or VIP movements can temporarily close airspace, resulting in diversions.

Several terms are commonly used in discussions about flight diversions:

Alternate airport: A designated airport where a diverted flight can land if conditions at the original destination are unsuitable.
Holding pattern: A circular airspace where flights are kept while awaiting further instructions or improved weather conditions.
Estimated time of arrival (ETA): The estimated time when a diverted flight is expected to arrive at its final destination.
Flight cancellation: In some cases, a diverted flight may be canceled if conditions at the destination remain unfavorable or if the diversion significantly delays the flight's arrival time.
