Thanks for your help in this endeavor. The links to past discussions were especially helpful, though I'm looking for a bit more data than they were.</font>
I would - as B747 suggested - pursue the IATA folks. If you call around at any phone numbers you find on thier website, you might be able to find someone sympathetic to your cause (academic) and might be able to either loan you or let you have stuff.
Also, some travel agents may have limited info.
