The prediction for WS4140 is based on the aircraft actually observed or claimed to operate this route, not a generic fleet-wide guess. No aircraft observed on this route. Score reflects the fleet-wide rate for the recorded aircraft type B738: 94.0%. A confirmed, dated passenger sighting for this specific flight can override this when one exists.
No prediction can guarantee a specific aircraft. Airlines perform last-minute equipment swaps for maintenance, operational needs, or schedule changes — meaning a Starlink-equipped tail can be replaced by a non-equipped one on the day. A score of 80% or above means historical data strongly favours Starlink on this flight, but it is not a guarantee. For the most reliable information, check the airline's gate display or app on the day of departure.
