ICTs and the Internet have dramatically increased the number of choices for consumers. Until the emergence of the Internet consumers could only access major brand names and also those organizations in their immediate vicinity. Consumers can now have much more choice for searching and subsequently purchasing on the Internet. The choice is availed from single products to dynamically packaging holidays. For example with the fast expansion of no-frills airlines such as easyJet and Ryanair, as well as with holiday packages and hotel rooms discounted at the last-minute, travellers can enjoy low cost travel. Oorni and Klein, however, found that low cost airlines have high online booking ratios because they offer simple products and are pursuing a direct sales strategy. Other airlines with complicated yield management strategies simply obstruct consumers to search for flights efficiently without expert assistance. Leading global online travel agents, such as Expedia, Orbitz, Lastminute.com, Opodo and Travelocity, are mainly successful for their provision of a platform for one-stop shopping with significant improvement in usability and interaction design. Comparing with traditional travel organizations, making websites more user-friendly and with simple pricing could help attract customers to complete the online transactions.
