Forgive me if there's a long thread about this already. With mid-air internet availability growing, I have to wonder whether VOIP is allowed on the plane. I haven't seen any official restrictions or notices. Maybe I'm looking in the wrong places. I think whether one should be allowed to VOIP on the plane from a social disturbance standpoint is perhaps a matter for a separate thread. I'm just wondering if it's technically permitted. If not, by whom?
