Questions
How do I check if AS1139 has Starlink?
Pick your travel date above. About 2 days before departure, Alaska Airlines assigns the aircraft, and the answer comes from that aircraft. Earlier than that, you get a probability based on the aircraft that recently flew AS1139.
How accurate is this?
We combine Alaska's own status data, public fleet data and the aircraft seen on each flight. Aircraft can change up to departure, so check again the day before you fly.
