Question 1

Does flight WN4877 have Starlink WiFi?

Accepted Answer

We don't yet have enough data to give a confident Starlink prediction for WN4877. Visit the Southwest Airlines page to see overall fleet coverage and rollout status.

Question 2

How accurate is the Starlink prediction for WN4877?

Accepted Answer

The prediction for WN4877 is generated by a five-factor confidence engine: (1) fleet coverage ratio — what percentage of the airline's fleet is Starlink-equipped; (2) aircraft type match — whether the typical aircraft on this route carries Starlink; (3) verified aircraft sightings — confirmed Starlink observations on the specific aircraft operating this route; (4) live flight observation data — aircraft assignments captured from our flight tracking system; (5) airline rollout status — whether installation is active, rolling out, or only announced. These factors are combined and weighted to produce the 0% score shown.

Question 3

Can I guarantee Starlink on flight WN4877?

Accepted Answer

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.
