Again, feel free to do whatever makes you happy. But I'll warn you, I've seen several people attempt this on domestic flights...and they got slapped down..hard. One of them even got escorted off the plane....so..at your own peril.I will sneer, point and laugh, because that is what i do with sheep, as for another matter i don't suffer internet keyboard tough guys, i know you don't care about my story because it proves you wrong.
