No big event in the region around that date from what I can see. Also, quite a few routes from the US to Europe are well-booked Su/Mo/Th/Fr in C for obvious reasons (US-based pax fly out Su/Mo, EU-based pax fly their return Th/Fr).
So if there are a few more seats booked on LH463 than, say, a week earlier, it may be just by chance and nothing with a structural explanation. People love to see a pattern or a system when there is none.
Keep in mind that even the models used by revenue management are statistical ones. They can't offer a structural explanation for a single flight on a given date, either.
