Despite improved customer-satisfaction ratings at several e-commerce companies, online travel sites still suffer from security, performance and customer perception woes that cause potential travelers to put down their mouse and pick up the phone to book trips.

Forrester Research found that in the light of recent survey data those who book travel continue to resist the Web as their main resource for making reservations. The research firm polled about 5,330 North American consumers in the last quarter of 2006 to determine exactly what prevents them from putting their faith in online travel sites. To start, the top-three most common reasons for those who book travel not to stay online to make reservations include concern over credit-card security, Web-site performance issues and limits on the actions they could take online.

"[Forrester] data shows that there are some nagging issues that keep Web travelers from booking online," a recent Forrester report reads. "Three reasons -- concern about credit-card security, in ability to make specific requests online and frustration with Web-site performance -- have shown noticeable growth in one year."

Specifically, the number of consumers concerned with submitting their credit-card information online has doubled. About 9% cited this reason in Forrester's 2005 poll and in 2006 16% said, "I didn't want to submit my credit-card/payment information over the Internet." Forrester deems this reason as a "red flag for all travel sellers," because it is also a concern for Web site visitors that limit the online time to researching a trip and book it offline. Dubbed lookers, 27% of this class of online travel planner in 2005 said they book offline for fear of credit-card theft, and in 2006 32% said that is the reason they use traditional travel-reservation methods.

"The growing fear of online identity theft presents a real and serious obstacle to continued online booking growth, as even travelers who have booked online in the past are now afraid to do so," the report reads.

Second, Web travelers cited limited capabilities with the online reservation system as a reason for booking offline. About 25% in 2006 and 19% in 2005 cited "an inability to make a special request, such as asking for a particular type of room or model of a car." Forrester says online travel sites must update legacy systems to reflect the ever-growing demands of savvy travelers. "Until travelers have the same control online to consistently specify everything they would to a call-center agent, the inability to make special requests will dilute travel's online sales success," the report reads.
