It’s nice to share. The behavioral data reporting trend continues today with new reports from BlueKai. The auction-based data exchange and user intent data bank is reporting that a significant travel upswing. It says online flight search actions increased by 45% from December 2009 to January 2010, with activity for domestic destinations up 44% and international destinations up 48%.

While a seasonal increase in travel related internet activity is expected, this year’s increase in flight search activity is particularly impressive given the slowdown in travel seen in 2009. BlueKai says factors contributing to the slowdown include the economic recession, new airline charges for ancillary services such as baggage and food, and widely known security-related issues in December. The 45% increase in flight search actions in January suggests that consumers are still actively showing their intent to travel by shopping for the best deals, and bodes well for stronger category performance in 2010.

Domestic trips made up 67% of researched flight search actions, while international trips made up 33% of intent actions. This ratio was unchanged from December to January. Las Vegas continued to be the leading domestic destination, with nearly 10% of all flight search actions in January, with volume of flight searches to Las Vegas increasing by 67.7% from December.  Florida destinations, including Orlando, Miami, Fort Lauderdale and Tampa also showed larger than average gains in volume in January versus December.
