Check the Starlink rating on other Alaska Airlines routes.
We don't have enough evidence to rate flight AS1423 yet. Alaska Airlines is actively rolling out Starlink across its fleet. See the Alaska Airlines page for fleet coverage.
Alaska Airlines uses Starlink satellite WiFi on equipped aircraft. Flight AS1423 operates PHX to SEA. We track Alaska Airlines' fleet rollout and aircraft records to rate flights as data accumulates.
The most reliable method is to check your specific aircraft. Flight-tracking sites and some airline apps show the aircraft registration close to departure. You can search that registration on StarlinkFlights.com.
The aircraft that operate AS1423 have not been checked for Starlink, so we cannot rate it yet. That is not the same as confirming they don't have it. Check back as more aircraft are confirmed.
No rating can guarantee a specific aircraft. Airlines swap aircraft for maintenance, operations or schedule changes, so an equipped aircraft can be replaced by one without Starlink on the day. A high rating means the evidence favors Starlink, but it is not a guarantee. On the day of departure, check the airline's gate display or app.
