Like I said the FWV use Enroute on any DL or DCI aircraft requires WiFi over a certain SSID network (that’s already there) unless you’re on the ground...it could very easily be blacklisted on other airlines SSIDs, if you wanted to use it on a non DL/DCI aircraft you’d have to purchase the WiFi access for that specific flight.
It’s a situational awareness tool, last I checked having more situational awareness is a good thing
