It is bonkers. My many flight trackers show no evidence of them going down though. We paid over $10k for 4 of us on SAS premium economy (into Stockholm, and back from Copenhagen). Super strange, but on our outbound flight - regular economy was MORE than premium economy. I have no idea what their algorithms were doing that week!
I had hoped to use AA mileage at least partially, but that was an absolute waste of my time no matter what parameters I used in my searches. The options were ridiculous 24h+ journeys. So we paid $$$. sigh. I spent at least a week freaking out to DH multiple times a day about that charge.
