I watched the Brazil - Croatia Match on an Airbus 319 from Vancouver to Newark. It took a little bit of fiddling around to get around the error messages. At first it wouldn't work, so I ran a VPN and then it worked. I did some work at half time (with the VPN off) and went back and tried it again with the VPN off and it worked fine. I watched the entire second half. Occasionally the network wouldn't keep up, but for the most part it was fine.
