Aggregator websites like Yahoo Travel and Momondo allow users to search and compare flight and hotel prices across different travel booking sites in one place. While Yahoo Travel targets a larger, more international audience, Momondo focuses on younger, more active users in Europe. Both provide benefits to consumers like easy search and price comparison across major booking sites like Expedia, Hotels.com and Opodo. Aggregator websites increase competition in the travel industry and help ensure lower prices for consumers as the market for these sites continues to grow.
