Seems like a nice enthusiastic guy and I say good for him for making the most of his situation.
I have no wish to trawl through all his photos but if he's not taking them during flight I don't have a problem with it. While I would never suggest anyone post such pictures, I would also hazard a guess that EK will be quite happy to have such a positive spin on things on Instagram. IMO no different to 'the lawyer' taking a selfie outside his office before going into work.
Very sad to see this person getting criticised so personally in this thread.
