What: Travelzoo (Nasdaq: TZOO) popped 11% in intraday trading today after disclosing impressive subscriber growth in the Asia Pacific region.

So what: Travelzoo's annual 10-K filing stated its Asia Pacific business surpassed 3 million subscribers last fiscal year. That is an increase of 1 million from the prior year, growth of about 50%.

Now what: The U.S. and Europe are still recovering from the financial crisis and could have subpar growth for years. Consumers in those markets have cut back on discretionary spending, including travel. That makes Asia Pacific an attractive market that can be a key driver of earnings growth.
