What Is a Flight Diversion?
A flight diversion happens when an aircraft lands at an airport other than its planned destination. It is a normal safety decision, taken when continuing to the original airport is not possible or not sensible.
Why flights divert
- Weather: fog, storms or strong wind at the destination.
- Airport closure: a blocked runway, an incident or an airspace restriction.
- Medical emergency: a passenger needs urgent care.
- Technical issue: a fault that makes landing sooner safer.
- Low fuel margin: after long holding; see fuel reserve.
What happens after landing
The airline decides based on the situation. The options include waiting for conditions to improve and flying to the original destination, switching to another aircraft, arranging buses or cancelling the flight and rebooking passengers. Airlines usually arrange meals and accommodation if there is a long wait.
Alternate airports
Flight plans name alternate airports; see alternate airport. In Pakistan, flights into foggy northern airports may divert to others.
On a tracker
You may see the aircraft heading away from its destination, circling or landing elsewhere. A go-around is not a diversion: the aircraft tries to land again at the same airport.
What to do as a passenger
Follow crew instructions, stay informed and contact those waiting for you. See delay vs cancellation vs diversion and the diversion glossary entry.
