Do you get the ATPCO database too?
How about a list of business and first class fares available globally by city pair and sorted from lowest to highest CPM. Calculate the CPM via origin destination to be easy or via the MPM for each fare if you're sporting.
I'm assuming all the predecessors of this died off due to the expensive ATPCO db and the alternative of querying every possible city pair through the GDS was also too expensive.
