In the US, it’s free on Delta for SkyMiles members, which is in turn free to join. It’s also free for everyone on JSX with no strings, and they actually are the first airline I know of to use StarLink.
Additionally it’s free on most US airlines for T-Mobile customers, but only on devices that actually have T-Mobile SIMs (so not most laptops).
