JetBlue offers a free version of Fly-Fi and a paid service. The free service is enough to browse the internet, check your flight map, and stream some things. Plus if you are an Amazon customer, you get access to Prime features like streaming television shows. The paid plan, as expected, delivers faster speeds which can support stronger streaming.
The good news here is that no changes are coming to the offering, but the fact that it is now available on every JetBlue flight.
