I have flown on several 5-6 hour Alaska Airlines flights over the last three months, which utilize GogoEntertainment, several of these flights with 2 kids and iPads. Only to have my kids in tears because the movie app either works for half the flight, works on one iPad and not the other, or doesn’t work at all.
After the first flight when it didn’t work, I reached out to their customer service for help, and was told I needed to use their chat feature while in flight to trouble shoot, however, the chat feature has never worked while in flight. And once you land you can no longer try and chat because GogoEntertainment is no longer available. When you send them an email, with screen shots of your issues, their only reply is to use the inflight chat. When I wrote to them saying I did try that, but it wouldn’t work, they said “Chat is always available”, which is flat out BS because I even showed the flight attendant, and spoke with others around me having the same issues, and not one of us could use the inflight chat nor the movie features.
So my advice is download it, if it works it works, but definitely don’t count on it as your main source of inflight entertainment because chances are, it won’t work for you.
