"High computer ownership rates and large urban populations provide the ideal infrastructure for Internet services," said Parita Chitakasem of Euromonitor. "With double-digit growth forecast in the number of urban households between 2006 and 2010, India is showing great potential for online businesses and as a result, great potential for online travel retail."

Japan has the largest online travel market in Asia, followed by South Korea, but the market is growing fastest in other countries. Vietnam's online travel market will nearly triple by 2010. Hong Kong's market will double. Indonesia's market will grow by 83%, Malaysia's by 82% and China's by 71%.

Demographics are helping drive this growth. Asians older than 65 are getting more comfortable with the Internet, and they are bringing high disposable income levels with them when shopping for travel online.
