There was a short flight to Amsterdam. This was fine, except that it seemed to take an unusually long time to complete boarding.
Flight to San Jose was good, despite the length of the journey. Comfortable seats, leg room was fine. Windows which adjust the amount of sunlight, without blinds. Service was excellent. The food was good throughout, personally we might have preferred slightly more savoury options but it was still good.
We fly frequently but first time with KLM - will certainly be a preferred choice in the future!
