At the National Business Travel Association's convention, industry insiders discussed the affects of the economic downturn and offered predictions for when spending on business travel would return to pre-recession levels. Some say they expect the turnaround to start next year, while others say it will be a matter of years. "We want to be optimistic about some of the upward trends we're seeing," said Sabre Holdings Chairman and CEO Sam Gilliland, "although what we could be experiencing is just bumping along the bottom. Considering where we've been, bouncing along the bottom isn't such a bad thing, frankly. We are beginning to be encouraged."
