The heart of the matter is the fact that the industry is changing. The GDSs are threatened by new technology that will make them obsolete, and American just happens to be the first carrier to substantially challenge that history.

Likely too large of an impact to sales, the entrance of Sabre to the distribution battle got American running to the courts.
