Hi,
I was looking at CDG<>HND flights lately and had written down all the dates where "cheap" premium economy was available (at 513€ per segment for the direct flight). Now 5 days later all those dates have increased to 561€.
Since all dates have stepped up their prices at the same time and of the same value, it doesn't seem to be directly connected to availability at each of those dates. So what could this increase be about, and could the fares return to their status from 5 days ago? Thanks
