CNET: Online travel bookings to take off, study says

Jupiter believes online travel sales will rocket to $91 billion in five years, up from 2004's estimated $54 billion. That's one out of three travel bookings in 2009, according to the research firm, but constitutes a relatively slow compound growth rate of less than 12 percent. Interestingly, Jupiter things that much of that growth will come not from the expansion of existing travel portals like Expedia, but instead from the direct sales on sites of individual airlines, hotels and other travel providers.
