The only problem is that I don't have access to what the true loads are. [Well... unless I pull up seat maps on PTO and start counting seats everyday then i might get close to what the true loads are]

The only data that I can use are the ones from ITN and those info already factor in what AC yield management thinks. So if I am developing my own hypothesis based on the ITN data, it's nothing more than what AC already thinks. Those data are effective for helping me look at which flight I should pick for upgrade purposes but I am not sure whether it'll be useful beyond that.

Do you think there is a better way of doing it or acheive what you are suggesting based on those ITN/PTO data?
