By now, the global travel industry is fully aware of the massive scale of the market in Asia. Across the region, more than $30 billion in annual online travel spend is in play, according to a report by Google and Temasek. "Asia's corporate travel market is booming," according to Amadeus. "Driven by China, India, and the emerging economies of Southeast Asia, spending on business trips is expected to soar to $900 billion by 2025 from the current $400 billion," the firm said. And that same year, corporate travel spending in the region will "account for half of the world's total," the report continued.
