You may not be familiar with the different Gogo systems that are installed on commercial aircraft.

Gogo ATG, as in Air To Ground - god-awful slow

ATG-4 - just slow

Satellite Ku, as been installed in a lot of AA and DL long-haul aircraft - tough to call it broadband, and both carriers prohibit video streaming, IIRC

Satellite 2Ku - not too bad, actually, if you can live with the latency. I've seen about 12 Mbps down. DL has more than 400 narrowbodies with 2Ku; I've stopped counting.

Some TV on Gogo 2Ku systems actually is IPTV, not a satellite TV capture. The number of channels (and resolution) is very bandwidth-dependent. https://www.gogoair.com/learning-cen...ve-tv-service/
