Starlink has been deployed on JSX for almost a year now and I've taken quite a few flights on their Bay Area to LA and Vegas routes. Despite 20 people on the planes, no one has ever been on a video conference, though I could see it becoming an issue with a broader consumer base.
I just did an Antarctic cruise that had StarLink. While it sucked to have internet access - like, I wish I could’ve been fully disconnected - it did allow me to run my stuff remotely and ultimately have more time out there.
