Niall, on seeing the picture was angry and responded on twitter saying "I think this sh*t is unreal. I mean if you can't sleep on a plane without people taking photos of you, what can u do".
We feel bad for Niall, he was obviously being very friendly to the fan during the flight and asked politely for no photos. Ahhh the first world problems of a superstar...
