Well im flying from nyc to nassau bahamas today on 2 delta flights with gogo wifi. I noticed they offered 15 minutes for free as a credit card promo. After the fifteen minutes were up i was browsing on atomic browser and i was able to log in again for another 15 minutes using basically "anyletter" at gmail dot com. So i dl'd a bunch of free browsers and have had free wifi access for both of my flights!
Hope this helps
