What Is Diversion? Definition & Meaning in Aviation
A diversion is when a flight lands at an airport other than its planned destination.
In plain language
Common reasons are weather, an airport closure, a medical emergency or a technical issue. After a diversion the airline decides whether to continue to the original destination, bus passengers or cancel.
Example
A flight to Lahore in dense fog may divert to another airport and wait for conditions to improve.
Why it matters
A diversion changes everything for passengers: the airline must decide how to get you to your destination. Knowing the term helps you ask the right questions about rebooking, accommodation and refunds.
