Questions
How do I check if AS3109 has Starlink?
Pick your travel date above. Alaska Airlines assigns the aircraft about 2 days before departure, and the answer then comes from that aircraft. Before that, you get the share of the aircraft flying AS3109 that have Starlink.
How accurate is this?
We combine Alaska's own status data, public fleet data and the aircraft seen on each flight. Aircraft can be swapped before departure, so check again the day before you fly.
