Gate to gate (if the plane door is closed) wifi has been a thing for most (all?) of the US airlines for awhile. Delta's wifi is ok, but I routinely have issues. It could be a combination of older technology on the plane and worse satellite network, but it's supposedly nowhere near as good as plane with Starlink.

I also use Starlink at my house in Italy. I'm in a decent sized town, but there is no fiber available. It has worked great, and more importantly took about 10 minutes to setup.

Starlink speed and bandwidth is way ahead of any of the existing satellite internet providers.

I believe Viasat internet satellites are placed in geostationary orbit, whereas SpaceX Starlink is not, so the service Viasat provides is already blown out.

Long latency makes Viasat good for some things and not so good for others.
