Data point counter to the other two replies you've gotten: I -- and, I perceive, most people, both introverted and extraverted -- am neither overjoyed nor horrified to have someone attempt to start a conversation with me on an airplane. I would say that as long as you can successfully read negative feedback, and disengage from the conversation, it is absolutely reasonable to attempt to start a conversation with a stranger next to you on an airplane.

Now, I can't tell if the objection is to 1) the mere act of attempting to talk to someone on an airplane at all, which I can't really understand, or 2) to the particular manner of your attempt, which does seem a bit talkative / familiar, and could perhaps be toned down.
