The prediction for RS903 is based on the aircraft actually observed or claimed to operate this route, not a generic fleet-wide guess. No route-specific aircraft evidence needed: A321 is an operator-wide claim covering every A321 aircraft in the fleet (0.0%). 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.
