GOGO Inflight internet offered on many major airlines allows internet access in a few different options. An "hour pass", "day pass", and "month pass". Unkowningly (or possibly in real fine print, I can't be sure) you're agreeing to be billed reoccurringly if you select the month pass. In my case $49.95 each month.
As I write this, I see on wikipedia that they've been sued in a class action lawsuit in 2013 (ruled on in 2015) for this exact same issue (cited below). However, its now 2016 and I've been duped in the same way. I consider myself an average internet user and someone of at least average intelligence. I was not under the impression I was signing up for a reoccurring service, I never received an email from GoGo confirming a service agreement, and they don't send invoices out when they charge your credit card.
I called their customer service number to ask that the charge be reversed. The rep told me she would "submit the request to her supervisor". Its been over a week. No word back yet.

In 2013 Gogo was the subject of a class-action lawsuit, for allegedly not mentioning recurring charges on their website nor notifying customers that these recurring charges would be made.[58][59][60] A New York federal judge, Jack Weinstein, ruled on April 8, 2015 that the suit (Berkson, et al. v. Gogo LLC, Case No. 14-CV-1199, in the U.S. District Court for the Eastern District of New York) for claims that the company tricked consumers into signing up for automatic monthly renewal of Wi-Fi connections[61] was allowed to move forward. In an 83-page memorandum and order of the case, the judge wrote, "the average internet user would not have been informed. . . that he was binding himself to a sign-in-wrap" and that the wrap contract thus "does not support the venue and arbitration clauses relied upon by defendants."
