What happens when a flight is diverted?

Answer

The aircraft lands somewhere other than its scheduled destination, and what follows depends entirely on why — because a diversion for weather and a diversion for a medical emergency produce completely different experiences for passengers.

Why diversions happen:

Weather at the destination — fog, thunderstorms, crosswinds beyond limits, or a snow-closed runway.

A medical emergency on board, where the captain lands at the nearest suitable airport.

Fuel. Aircraft carry contingency and alternate fuel; if holding has consumed it, they must divert rather than continue. This is normal planning, not an emergency, though a declared minimum-fuel situation is treated seriously.

A technical issue, which is frequently precautionary rather than dangerous.

Disruptive passengers, which is more common than people expect.

Crew duty limits, where the crew would exceed legal working hours before landing.

Airport closure, a runway blocked by an earlier incident, or airspace restrictions.

What happens on the ground. This is the frustrating part, because the diversion airport may have no handling agreement with your airline, no available gate, no immigration facilities for a flight that was not expected, and no crew hours left. Passengers are frequently kept on board while fuel is taken and clearances obtained, sometimes for hours, because disembarking into a terminal that cannot process them creates a bigger problem than waiting.

Then one of three things: refuel and continue, once weather or crew hours allow; wait for a replacement crew or aircraft; or offload passengers and transport them onward by road or on later flights.

Your rights. Where passenger rights rules apply, care obligations — food, communication, accommodation where needed — generally apply from the point of significant delay, regardless of cause. Compensation is a separate question and usually turns on whether the cause was within the airline's control: weather, medical emergencies and air traffic restrictions typically count as extraordinary circumstances, while technical faults frequently do not.

Keep evidence — boarding passes, receipts, and the airline's stated reason.
