Fly air is now operating this A300 into AMS. The aircraft carries "Sultan Reizen" (in english : Sultan Travel) and still wears the colours of it's previous operator. I presume that was JAS (Japan Air System).
I also think we'll see the A300 more often this summer, because it seems like Fly Air flies regularly to BRU. I even saw this morning on the biac site that there were two Fly Air flights today (both with 757 apparently).
