perfectly fair, i admit i've done some flight "hacking" myself. The reason i bring it up is because it is well know that airlines prices their flights between city pairs, not based on the legs. For instance a flight, between jfk and lax through chicago could cost more than the sum of those two same exact flights. This would be an opportunity to build your own ticket. I admit there are significant downsides with delays and reroutings, but if google presented the information to the public it would add transparency to a very opaque system and it may lead to a change throughout the industry in the way tickets are priced. After all google's mission statement is to organize the worlds information
