 Well, it is rocket science, but if it's not working properly, which sometimes it's not, especially with the old style satellite internet, just ask for a refund and they will give it to you. So the in-flight experience was amazing. What did I do? I tested downloading an entire movie before I even took off. I've never been able to do that in all the years I've been flying. Downloaded an entire two-hour movie or so while I was still at the gate.
