Best Time to Book a Cruise
There is no single best time to book a cruise, and the most repeated advice points at the wrong window. Almost every guide says book 6 to 12 months ahead. Measured against each fare's own peak, that window sat about 11% below peak in our data, while 31 to 100 days out reached about 16%. It also flips by region: Mediterranean fares kept falling to the last month, Caribbean fares stopped falling after about 180 days. Here is the curve for each, and when booking early is still the right call.
By the CruiseLookup research team. We track per-cabin cruise prices daily across 22 lines and analyze our own fare history, so the numbers here come from prices we actually recorded. Based on 4.3 million fare snapshots CruiseLookup logged across 34,681 sailings and 22 cruise lines between March and June 2026.
Everyone says 6 to 12 months, and nobody shows the fares
Search this question and you get the same answer everywhere: book 6 to 12 months out, the "sweet spot." The major line guides and the personal finance sites agree on it. What none of them include is fare data. The advice is inherited industry convention, repeated until it sounds measured.
We track cruise prices daily, so we checked. Booking 6 to 12 months ahead is not where the discounts are. It is close to the most expensive point on the curve, second only to booking more than a year out.
That does not make the advice worthless, and we get to why below. It makes it advice about availability dressed up as advice about price.
How we measured this
These figures come from our own fare-tracking dataset: 4.3 million price snapshots across 34,681 sailings and 22 cruise lines, recorded between March and June 2026.
For each sailing and cabin category we found that fare's own peak price, then expressed every later observation as a percentage below that peak, grouped by how many days remained before departure. Measuring each fare against itself means an expensive suite is never being compared against a cheap interior. Regional figures use our region tagging, so a sailing can count toward more than one region.
One limitation worth stating plainly. Our window spans about three months, so the short buckets can only contain sailings that departed between March and June. Alaska's season runs May to September and the Mediterranean's April to October, so those late-window numbers describe early-season departures, not a whole year. Treat the shape of each curve as reliable and the exact figure for a December sailing as unproven.
The best time to book depends on where you are sailing
This is the finding that matters, and the one no other guide has. Average percent below each fare's own peak, by how far out you book:
| When you book | All regions | Alaska | Caribbean | Mediterranean |
|---|---|---|---|---|
| 365+ days out | 8.5% | 9.0% | 9.8% | 7.3% |
| 181 to 365 days | 10.9% | 9.8% | 13.0% | 8.1% |
| 101 to 180 days | 12.9% | 14.4% | 15.4% | 14.9% |
| 31 to 100 days | 15.5% | 14.8% | 13.6% | 19.0% |
| Inside 30 days | 16.2% | 17.4% | 13.6% | 23.3% |
Higher is a deeper discount against that fare's own peak. Cell samples range from about 3,000 observations (Mediterranean, inside 30 days) to about 175,000 (Alaska, 365+ days).
Three different shapes, and they lead to three different decisions:
- Mediterranean rewards waiting most: 7.3% a year out to 23.3% inside the last month, the steepest slide of the three. The Eastern and Western split is in our guide to booking a Mediterranean cruise.
- Alaska rewards waiting too, reaching 17.4% inside 30 days, but note the flat stretch: 9.0% at a year out and 9.8% at 6 to 12 months. Moving your booking from 12 months to 8 buys almost nothing. Why we still suggest booking Alaska early is in our guide to booking an Alaska cruise.
- Caribbean reverses: it bottoms out around 101 to 180 days at 15.4%, then gets worse closer in, at 13.6%. Waiting until the last month is the wrong move here. The sub-region detail is in our guide to booking a Caribbean cruise.
The Caribbean exception has a straightforward explanation. Caribbean ships sail year round on repeating short itineraries and fill steadily, so there is less distressed inventory to dump at the end. Seasonal regions face a hard deadline: an Alaska ship cannot sell July twice, so unsold July cabins get discounted hard in June.
Book early when the cabin matters more than the fare
None of the above says book late. It says the fare falls late. Those are different claims, because the discount and the choice move in opposite directions. A cheap fare inside 30 days is cheap partly because what remains is what nobody picked: an inside cabin by the elevators, a guarantee category where the line assigns your room.
So the honest rule has two branches. If you need a specific thing, a connecting cabin for a family, an accessible room, a particular ship for a milestone trip, book early and accept that you are buying certainty rather than the lowest price. If your requirements are loose and you can walk away from any single sailing, the later windows are where the money is.
Either way you are not stuck with the fare you booked. Most sailings cut prices at least once after booking, and a cut before your final payment date is usually claimable, which is covered in how to get a cruise price drop. That is what makes booking early survivable: you can book for the cabin and still collect the discount later.
Two smaller timing effects, in order of size
How far ahead you book is the big lever. Two smaller ones are worth knowing once you have settled the window:
- Which day you buy: cuts cluster on the weekend, with 77% of the price moves we logged on a Saturday being cuts against 28% on a Wednesday. Real, but small. See the cheapest day to book a cruise.
- Where the sailing is in its own lifecycle: the final-payment date around 90 days out releases cancelled cabins back into inventory and triggers a fresh round of discounting. See when cruise prices drop.
Neither changes the answer to this page's question. They tell you when to expect a cut once you have decided roughly how far ahead to buy.
Pick the window, then let the fare come to you
Put it together and the process is short. Decide whether you are buying certainty or price. If certainty, book now. If price, aim for your region's best window: inside 100 days for the Mediterranean and Alaska, around 101 to 180 days for the Caribbean.
Then stop guessing. Open the sailings you would accept, read each one's recorded price history to see where today sits in its own range, and set a free price alert so you hear about the cut instead of hunting for it. Reading the chart is covered in cruise price history.

How far in advance should I book a cruise?+
On price alone, later than most advice suggests. In our fare data the 6 to 12 month window sat about 11 percent below each fare's own peak, while the 31 to 100 day window reached about 16 percent. Book early when you need a specific cabin on a popular sailing, because availability, not price, is the reason to commit early.
Is it cheaper to book a cruise early or last minute?+
Later is usually cheaper, but it depends on the region. Fares kept sliding toward departure on Mediterranean and Alaska sailings, reaching 23 percent and 17 percent below their own peak inside the last month. Caribbean sailings behaved differently: they bottomed out around 101 to 180 days and got slightly worse after that.
Does the best time to book vary by destination?+
Yes, and by more than most guides admit. Comparing the same measure across regions, the Mediterranean rewarded waiting the most and the Caribbean rewarded it least. Caribbean sailings run constantly and fill steadily, so there is less unsold inventory to discount late. Seasonal regions have a harder deadline and discount harder against it.
Should I book during Wave Season?+
Wave Season, roughly January through March, is when the lines run their biggest promotions, but those arrive mostly as perks rather than lower fares. Our measurement window does not cover January through March, so we make no claim about whether wave fares beat other months. Judge any wave offer against the sailing's own price history.
What is the risk of waiting to book?+
Losing the cabin. The late discounts exist because a ship still has space, so the categories left are the ones nobody wanted. On a popular sailing, a specific balcony or a connecting cabin can be gone months out. The practical answer is to book when the cabin matters and track the fare afterward, since a drop is usually still claimable.
