This may not be the place or time to ask this but here goes anyway:

How do the travel indexing sites like Kayak get their data? Surely they don't index or consume APIs from the travel companies individually?

A company called ITA, now owned by Google. http://www.fastcompany.com/1666092/google-acquires-airline-d...

And where does ITA get it's data. I assume there must be a few competing standards, and the airlines use one of them to give their data to ITA. Why can't other companies get the data directly from the airlines?

ITA get its data from ATPCO (http://www.atpco.net/atpco/aboutatp.shtml) the clearinghouse for flight data.
