Hi Love_to_Travels

Sorry to say, but you'll probably do better with Google and secondary sources than you will with flyertalk. But it would be great if you could share your findings with us when you submit your paper, as it's of great interest to most of us here.

LT,

You should probably look through this thread if you haven't yet; maybe some of the links will be helpful:

Not something I have a ton of knowledge about myself, but it might be a useful starting point.
