Someone pointed me to this thread after I posted the following topic:

http://www.flyertalk.com/forum/travelbuzz/1721030-website-ask-where-people-flying-why.html#post25649019

I went through some of the original replies and it is somewhat similar to what I have in mind but I am not sure if it answers the question of 'why'?

While it is nice to know where you are flying to, I am more interested to know the answer of 'why'

If you are flying to New York, why? Is it to attend a concert? See the new WTC? Run a marathon.

If this thread addresses the 'why' question as well, please let me know , otherwise I would love to open a new thread.
