Capacity control: This refers to who will control the sale of inventories of hotel rooms, airline seats, auto rentals, and tickets to attractions. Presently, owners of these assets are in control of their sale and distribution, but increasingly control is falling into the hands of those who own and manage global reservation systems and/or negotiate for large buying groups. Factors involved in the outcome will be telecommunications, software, available satellite capacity, governmental regulations, lim- ited capital, and the travel distribution network.
