Preference-based display of flights (I'm thinking). Once upon a time, AA owned SABRE and all the flight information was in the one GDS (Global Distribution System). Then somebody at SABRE got the bright idea to preference the order so AA flights were always on the first page and all other airlines were on the second page. Most bookings were made from the first page. This was then made illegal and they said some gobbledy-gook like: "you can't preference the display, you have to show a reasonable number of flights, all in the same format, and sorted by time, price or duration". Or something. I can't find a reference to it, but it had to do with SABRE's virtual monopoly on global travel distribution (inventory, agents, etc) and regulation / de-regulation of the travel industry.
