You can't really haggle with a computer system can you? And even if we'd accept that as haggling the company has way more power in the transaction. This just seems allowing the company to capture ever more of the consumer surplus.
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.
