100% load factor on one way, 0% on return. What am I missing?

When did you activate the flight?

2 days ago. The one for the day after is already almost full but 0% on return.

Which server? 2 days ago demand calculation for the return leg is done. Perhaps a bug if on Bleriot.

Otto. How to report this bug?

This doesn’t sound like a bug, but rather someone needing to do some price management…
