Posting with the Gogo internet service on AA18 right now. Broadbandreports's test is reporting ~1.7Mb down and 170Kb up. Latency varies between 65-180ms, which the best times using Chicago and NY based tests.
Interestingly, a person wearing a Gogo internet service "uniform" just walked by and asked me if I had any questions.
Can't use being being on a plane as an excuse for being disconnected anymore... (Well, a few planes for now.)
