I had access to it on a long-haul AirFrance flight. While I avoid doom-scrolling in my daily life because there's better stuff to do... on a long haul flight it's a surprisingly good way to pass time intermittently. I still just watched pre-downloaded dropout for 80% of the flight but when I was too tired to appreciate it I'd turn my brain off and watch a bit of that wonderful doom-scroll slop.

The fact that it's powered by starlink is disappointing due purely to Elon Musk's involvement - but this is one of the better use cases for satellite internet technology. I'm not going to go out of my way to book with airlines that use the service though.
