Aggregator travel sites like Mobissimo and Yahoo Travel allow users to search across multiple online travel agencies (OTAs) to find the best rate for flights and hotels. They aggregate availability and prices from Expedia, Orbitz, Priceline, Hotwire and more. This saves users time compared to searching each OTA individually. While aggregators help users find low prices, OTAs may adjust prices and offers to remain competitive. It's also possible to occasionally find better deals directly on airline or hotel sites than through an aggregator.

9. My point of view This is not really easy to find the best rate for a trip on the Internet, because we can't naturally know all the Ota, and use time to compare them. Agregation websites do it for you in less by 1minute. With that type of websites, the demand could find the lowest price, that means that he can find the best rate of the market, I wonder the evolution of the price, thank to this type of tools. However, Ota could play on room categories, and special packages to stay attractive. And people have to keep in mind that the Agregators don't compare directly with the hotel or flight company, and could find a better price over agregation sites.
