With bing.com/travel acting as an intermediary in the value chain, the world of online travel now has a new heavyweight to contend with. Ironically, www.kayak.com has purchased sponsored links thanking Microsoft for copying its model and interface. 

Bets are open to see if Microsoft, who at one time had created Expedia before eventually selling it, will grab a share of travel-related searches. 

So far, bing.com/travel has 67’000 pages indexed in Google, whereas kayak.com has 4’890’000. Over the next few months, we will be eagerly checking Hitwise and Comscore stats to see who will come out on top!
