It's interesting that you mentioned DL. I'm assuming DL uses Gogo ATG rather than satellite for North American flights? I have never used satellite internet so I can't compare. I recently flew out of ATL on DL and I used Gogo. It was ok at best. I'm not sure if it's fast enough to stream Netflix. I mostly browsed the web and used messaging on that flight. It still doesn't feel very snappy compared to using Wifi on the ground or even the LTE network if that makes any sense. I can somewhat feel the lag. It's better than nothing though.
