Iberia uses Starlink satellite WiFi on equipped aircraft. Flight IB421 operates MAD to BCN. Our Starlink probability score for this flight is 0%, based on Iberia's fleet rollout data and confirmed tail numbers.
The most reliable method is to check your specific tail number after check-in — your boarding pass or the Iberia app may show the aircraft registration. You can then search that tail number on StarlinkFlights.com. Alternatively, our probability score for flight IB421 is 0% based on current fleet data.
The prediction for IB421 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: A320 is an operator-wide claim covering every A320 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.
