Starlink is simply the means that the ship uses to connect to the internet, whether you have basic Wi-Fi service or premium. Basic service allows one to send and receive emails, download and print a boarding pass, maybe send a text. Premium allows streaming data - watching TV shows or video, listening to Pandora or some other streaming music service. Either way, with Starlink your service should be much better than it has been on this service in the past. We were on the Apex in April and were really pleased with our premium internet quality on board.
