The pilot-in-command makes the final decision to divert a flight, but they work in coordination with the airline's dispatchers who suggest suitable airports based on factors like safety, weather, and available maintenance and
facilities. The decision is made for safety reasons, and while the nearest airport might be chosen, the best option is often an airport where the airline has the right facilities to handle the aircraft and passengers efficiently.
Factors influencing the choice of airport
1.Safety and suitability: The airport must be safe and suitable for the aircraft's current condition, considering factors like runway length, navigation aids, and available maintenance personnel and parts.
2.Weather: The weather at the potential diversion airport must be within the acceptable limits for landing.
3.Airline infrastructure: Ideally, the flight diverts to an airport where the airline has its own staff, equipment, and can more easily arrange for passengers to continue their journey, according to Flightradar24.
4.Fuel: The amount of fuel on board is a critical factor, as the flight crew must ensure they have enough fuel to reach a suitable diversion airport.
5.Passenger needs: Airlines also consider what resources are available to help passengers continue their journey from the diversion airport.
