starlink has some travel niches where it makes sense. However not many cross the ocean. military where you can't trust the nearby infrastructure is the other big one. Disaster recovery where the local system is not working isn't big enough to fund anything though it will use whatever they can get.

The cruise ship industry is $78B of revenue. He airline industry is $840B of revenue. Between the two, I think Starlink has enough customers crossing the ocean to be profitable, given how hard they drive down costs.
