The computer gives you, the consumer, a lot of power. You can very easily comparison shop - not simply view the cost of flights from every other provider on the same day, but also a day or two earlier/later, and if you are flexible, a week or month later. You can mix airlines, or plan open jaws. You can see the price of a rental car for all or part of the trip. Before travel was sold online, you went to a travel agent and had far fewer options.
