@ablaze @aaronpk Ah ok, that makes sense. I did some research on it couple of years back, and FAA always deferred to individual airlines to make the call on that. The airline has the authority to disallow calls, but it's not an FAA regulation. Some in-flight companies (like GoGo) explicitly forbids VoIP calls in their ToCs (at least used to) that you agree to when you join their network.
