yeah, i'm assuming this is up to 220Mb/s for the whole plane, not for each passenger.

airplane wifi is still going to suck.

Delta courtesy of T-Mobile has been solid in my experience. A few times not but in general it works really well.

I can't remember where or how I pieced this together, but I'm guessing that each plane will have two dishes (which will be bonded together), and Starlink is expecting bandwidth to improve to Gbit speed, so it will probably be 2 Gb/s down for the whole plane. Still not great if every passenger is streaming HD video, but I imagine with some "traffic shaping" (aka throttling) it will be pretty snappy for web browsing and small file downloads.

Netflix HD isn't that much. And no; two dishes won't give you 2 Gbps.

You'll need four in Ku Band (that's what's publicly in use)

To get 2 Gbps antennas in Ka, V, E or Q will have to be used.
