Alaska Airlines uses Starlink satellite WiFi on equipped aircraft. Flight AS77 operates SEA to ANC. Our Starlink probability score for this flight is 14%, based on Alaska Airlines' 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 Alaska Airlines app may show the aircraft registration. You can then search that tail number on StarlinkFlights.com. Alternatively, our probability score for flight AS77 is 14% based on current fleet data.
The prediction for AS77 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 B38M: 13.6%. 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.
