Consegui encontrar essa parte específica especificamente para o Gogo Air:
...Gogo may prioritize, restrict, or set limits (such as bandwidth allocations, or limits on types of content accessed or transferred) on your use of the Service for certain applications. In times of heavy network usage, this may impact the functioning of high bandwidth applications. As with any mobile broadband network, speed may vary due to your device, atmospheric conditions, terrain, network capacity, and aircraft location. Content, file sharing or multiplayer gaming requiring high bandwidth, such as VoIP, streaming audio and video, and file sharing, are given a lower priority and at times may be blocked or not work consistently...
Assim, parece que o streaming de vídeo provavelmente seria uma experiência ruim tanto para o usuário quanto para outros passageiros no caso da Gogo Air. Eu não sei sobre outros serviços.
