KLM - Royal Dutch Airlines

I do like KLM as an airline but sometimes hostess are not so nice.
I was so surprised as last monday on my flight from Amsterdam to Barcelona nearly 20% of the passengers were japanese, so I suppose there are many flights from Amsterdam to Tokyo and Osaka and that's why they make a stop over in Schipol and then come down to Barcelona.

KLM B777 approach Osaka:
