(6/4/2002) By Dennis Schaal ATLANTA -- Claiming the GDS pricing model is "broken" because suppliers pay almost all of the distribution costs, Worldspan said it is exploring ways to shift distribution costs to travel agencies, other distributors and consumers so that each link in the distribution chain can transparently select the services it values enough to pay for, said the GDS's chief executive Paul Blackney. "It's clear that the model is broken and the worst aspect is its opaqueness," Blackney said. "Suppliers are paying all of the costs and definitely don't derive all of the benefits." Asked what options were under consideration to lessen the burden of rising booking fees, Blackney said suppliers and consumers might choose from a menu of services. Over the next six to 10 weeks, he said, the GDS will talk with key agencies and organizations to solicit their recommendations. "We're interested in what agency organizations have to say," Blackney said. "I'm interested in hearing their ideas for creative solutions. "It's not an assault," he added.
