Err, right, you caught me. I should change the stuff that I am smoking before posting on FT

And whilst I do follow your reasoning, I also have made the observation that I have been disturbed far more times on planes by people who have had a drink too much (imagine the EK A380 Bar on a flight to the UK or the Netherlands) than by people talking to loudly into their phone/skype on board (in fact never so far).

Whatever, in the end it is probably exactly what you say, it is not AF that has blocked skype but orange
