How we confirm cruise price drops

We record prices daily-ish, per sailing, cabin type, and cabin grade from the inventory feed we use across CruiseCaptain. Public comparisons use per-person fares in USD and include the taxes and fees present in the feed.

History depth varies by sailing. A new sailing may have only a short record, while a long-lived sailing can have enough observations to support stronger confidence.

We do not use cruise-line "was" prices, percent-off banners, or marketing sale labels to decide what appears on Deals. Those can be useful context, but they are not the evidence for a CruiseCaptain confirmed drop.

We also refuse fake urgency and predictions. A future price might move either way; a confirmed drop is a record of a price we actually watched change.

Confidence describes the strength and freshness of the history. It never substitutes for exact-grade proof: even a high-confidence cabin-category signal stays off public drop surfaces when the grade identity is missing.

When the evidence is thin, stale, or mismatched, the sailing stays off Deals. That can make the page quieter, but it keeps the sale claim tied to data we actually observed.

Promo and eligibility fares are not yet visible on every premium line, and some lines publish richer public fare detail than others. When a public price is missing or ambiguous, we suppress the drop instead of filling the gap with a cruise-line sale label.

The confidence label is partly a history-depth label. A sailing with fewer observations can still be real, but it will not get the same confidence treatment as a sailing with a deeper, fresher record.
