I had Gogo Inflight Internet wifi on my MEX-YYZ flight 2 weeks ago and it kicked it near Corpus Christi, TX and worked near perfectly until somewhere around both KY and TN where it dropped off completely for 30 mins or so. It returned over OH and worked until below 10K feet on approach to YYZ.
Better than nothing to be sure, however, people using it for Skype sitting next to me in J is beyond ridiculous and rude.
Can you hear me now? How 'bout now? Better? Onnn thhhheeee pllllannnne here...
