Since two people asked: check twice a week, same days, and only act on a drop of $40+ per person. Checking daily trains you to panic-buy; the twice-a-week cadence has caught every real drop for my person’s route for two months, and the $40 threshold filters out the noise the airlines generate on purpose. The wording that works when you report it: "Down $X from last check, same flights, book-by unknown." Never dress it up.
