Their JFK-CTG route is not listed. I had a chance to try it out in early May. I was actually pretty surprised. It was pretty quick for basic surfing (when it worked). I did not try streaming netflix. Service started/ended around Florida and worked as far as midway toward the Dominican Republic. However, even when it was over the east coast, it would cut in and out. I hope they expand it internationally. I would love to be able to work the whole flight rather than half of it.
