Pertinent note: BonBook doesn't communicate with/use Google at all. Google link is just there for result comparison. BonBook has its own internal search+recommendation engine. And private beta let's you actually book the flights in two clicks via the checkout link. That's why you can also change/cancel them with an email. This is also probably why you are seeing LH > KL.. BonBook doesn't yet have access to KLM inventory. And haven't added non-USD currency support yet.
