The prediction for WS2857 is based on the aircraft actually observed or claimed to operate this route, not a generic fleet-wide guess. 2 of 2 observed flights on this route carry confirmed Starlink evidence; blended with the fleet-wide rate for B38M+B738 where this route has no evidence of its own: 97.0%. 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.
