Free GoGo InFlight WiFi Pass for signing up for a free trial account with ShareFile. No credit card is required. Code appears on the next page after you submit... don't even need to check email to retrieve. Takes 30 seconds. GoGo pass I received is valid through March 21, 2013, so must be used soon but very easy and valuable. http://www.sharefile.com/try/ar/?sr...gogoair&utm_campaign=promo&utm_content=laptop Can use a spare email address if concerned about spam, and even a spare name, phone #, etc Terms say a rep might call you, so I was sure to use some spares. Free ShareFile account could be useful though. If you have friends who want to try it from the same browser, popping a new Chrome Incognito window works fine. Enjoy!
