Where are the people focused on Australia, China, Japan, India, Korea, SE Asia, Hong Kong, Singapore an more. All of these countries are booming for online travel. Should you should be nervous if you are a Priceline exec in missing these markets? Surely they were were "boom fodder" markets in 2000 (places where stupid money was spend with no return) and therefore should be ignored. However each has subsequently proven itself as a destination and source for significant online travel potential. Especially in hotel only. In each of those Asian markets the number one online intemediary is a hotel only provider.
Congrats to Priceline for its expansion. With 11 million room nights a year they are a player in every market - in Europe they are a powerhouse. However there is space, profit, opportunity etc in Asia Pacific that they (and others) are missing by focusing expansion efforts in only in an easterly direction of Europe.
