Not sure if allowed here, but been looking at AY HEL-SIN for late summer with the family, and it seems the prices have drastically increased in the past week on almost all dates August/Summer. Prices were starting from 720-ish in economy and now almost all 1k+. I can't remember the original J price, but also jumped a lot.

Are these normal prices for this route? I've heard good things about it and looking forward to trying it
