What about the original WWW threads about sponsorship selections in the mighty Birdseed Airways? They might be a little irrelevant now for BA but useful for seclection tests is general and the insight behind the Psychometrics.
Also anywhere where somebody has specifically set out the process for an individual airline.
Oh and this is sad but perhaps a good slection of the modular vs Intergrated and the OATS, CABAIR, BAE debate. (although I suspect this might prove to be too hard without lobbying by the respective schools.)
