The Best Day to Book a Cruise for the Lowest Price

The best day to book a cruise is Saturday. You're 4.5× more likely to catch a real price drop compared to Monday, based on 700k+ price observations.

We track more than 35,000 sailings every week, and once we graphed all of that activity, the pattern was hard to miss. Saturday consistently delivered the strongest odds of a real price drop — even across different cruise lines, regions, and fare types.

This analysis is based on over 700,000 price snapshots collected across nearly a year of daily observations. Cruise lines adjust fares algorithmically now, and the weekend keeps coming out ahead.

This guide breaks down those patterns:

• The weekly pricing rhythm cruise lines follow
• The days they adjust fares
• When last-minute discounts actually happen
• How far out the average traveler should book

Let's start with the day-of-week results — because that's where the biggest surprise lives.

Key Findings at a Glance

Here's the quick version before we dive into charts:

Best Day of the Week to Book a Cruise

Before we get into the booking windows and seasonal patterns, the weekday trend is the one that surprised me the most. I expected mid-week to be stronger — older studies always leaned that way — but that isn't how modern cruise pricing behaves anymore.

What the Numbers Show

Saturday takes the crown.

• A 10.8% chance of catching a 5%+ price drop.
• It's also the only day where prices fall on average.

Friday sits right behind it at 9.4%, making the weekend the strongest 48-hour window for real discounts.

After that, the curve drops quickly:

• Thursday: 5.6%
• Tuesday & Wednesday: around 4%
• Sunday: 2.7%
• Monday: 2.4% (the weakest day of the week)

If you're checking once a week, Saturday gives you the best odds — roughly 4.5× better than Monday.

When we first saw these results, we ran the analysis multiple times throughout the week just to be sure. Saturday kept coming out on top across almost every cruise line, even the ones that normally behave differently from the pack.

Best Day by Cruise Line

Once we broke the data out by cruise line, the patterns became even clearer — and in a few cases, completely flipped. Some lines cluster around the weekend, others spike mid-week, and a couple behave in ways that don't match the usual travel-blog tips at all.

Royal Caribbean & Celebrity - Big Weekend Movers

These two lines light up the chart.

• Saturday dominates, with drop rates hitting the 20–23% range — way above normal.
• Fridays are strong too, but Saturday is the real standout.

If you sail Royal or Celebrity and you're deal-hunting, this is the window to watch.

Princess & Virgin - Friday–Saturday Split

Both cruise lines show a steady weekend pattern.

• Friday: noticeable bump
• Saturday: often just as strong
• Sun–Wed: mostly quiet

It's not as dramatic as Royal/Celebrity, but the weekend window still matters.

Carnival & Norwegian - Thursday Outliers

These two break from the weekend trend.

• Carnival and NCL peak on Thursday, with drop rates around 6%.
• Friday and Saturday aren't bad — they just don't stand out the same way.

If you're sailing either one, checking fares on Thursdays gives you the best shot at a cheaper cabin.

MSC - Friday Leaning, Not Weekend Heavy

MSC doesn't have a huge spike, but Friday comes out ahead. It's a more balanced pattern overall, with smaller swings compared to the big U.S. lines.

What This Means for Travelers

Each line follows its own pricing rhythm — but the end of the week is where most of the action is.

When Cruise Lines Discount Across the Full Booking Window

This is the dataset I check the most often. Booking windows tell you far more about pricing behavior than any sale banner or promo name ever will.

We mapped more than 700,000 price observations across the entire booking curve — from nearly a year out to the final days before sailing. Once the data was laid out, the pattern was obvious.

0–50 Days: The Strongest Window for Price Drops

This is where discount activity spikes the hardest. A full 33% of all price drops happen inside this window.

If the ship still has open cabins, this is the zone where prices move the most. Late shoppers have the best shot at seeing a meaningful drop.

The steep curve matches what we see every week when sailings hit their final payment deadlines. A fare can sit unchanged for months, then drop quickly once cancelled cabins return to inventory.

For reference, Royal Caribbean's final payment is typically due 75–90 days before sailing (and 120 days for longer itineraries), which often lines up with these late adjustments.

51–100 Days: The Second-Best Window

Stronger than expected — and far more active than most "booking strategies" online suggest. This window accounts for 24% of all price drops across the industry.

If you want a blend of cabin options and price movement, this is the range to watch.

101–150 Days: A Quiet Middle With Two Exceptions

Overall, the curve tapers off here (17% of all drops). But two lines behave differently:

This range favors a couple of premium brands, but not the industry as a whole.

150–250 Days: Mostly Quiet

This is the point where discount activity becomes thin.

Once you're past the 150-day mark, deals become the exception, not the norm.

250+ Days: The Lowest Deal Probability

Across almost every line, this is the quietest part of the pricing curve:

"Book a year out for the lowest price" — The data shows the opposite. Long-range booking has the fewest real price drops.

Booking early still makes sense if you care about the exact cabin you want. But low prices? They show up much later in the cycle.

How to Actually Use This

Early = certainty. Late = volatility. Middle = best of both.

Best Months to Book a Cruise - Patterns That Hold Up

Monthly patterns shift every year, but the demand waves stay surprisingly consistent. Even with our early dataset, the real-world behavior lines up with what we've already seen in our early findings.

Growing demand doesn't slow down pricing. CLIA's 2025 industry report shows passenger volume rising past 34.6 million and forecasted to hit 42 million by 2028, which explains why peak months rarely see price drops anymore.

January–March (Wave Season)

• Reduced deposits, WiFi/drink bundles
• Kids-sail-free style promos
• Strong value, even if fares don't bottom out

Late November (Black Friday → Travel Tuesday)

• Heavy promo stacking: upgrades, OBC, add-ons
• High value; fares don't always drop

April–May / September–October (Shoulder Months)

• Lower occupancy as families return to school
• Better Med/Europe pricing, softer Caribbean fares
• We saw this firsthand — prices loosened almost immediately

June–August / Holiday Weeks

• High demand, firm pricing
• Few real drops — book early and reprice

A Simple Way to Think About Best Months

Last-Minute Deals - When Waiting Helps and When It Doesn't

Here's the part people argue about the most. Some swear by last-minute deals, others say they never happen. The truth sits in the middle — and you can tell which way a sailing is leaning once you know what to look for.

When Waiting Can Save You Money

The ship still has space

If a sailing is close to departure and still has a good number of cabins available, prices often soften inside 50 days.

How to check availability:

• Look for multiple cabin types still open
• Click into a category and check for lots of deck options
• Try searching for 3–5 guests — if it still shows plenty of cabins, there's room

Shoulder-season trips

Caribbean in September or early December. Mediterranean in April or October. Alaska in May.

You don't care about the exact cabin

If you're not attached to a balcony or specific deck, waiting becomes easier.

Repositioning cruises

These often drop late because they appeal to a smaller audience.

Pro pattern I watch: If a fare moves every few days inside the last 40–50 days, the cruise line is actively adjusting.

---

When Waiting Usually Backfires

Summer and holiday weeks

These fill early. Prices rarely drop.

New ships or "hot" itineraries

These almost never discount late.

Alaska in peak season

June–August sells out early, especially balconies.

You need flights

Airfare can wipe out any cruise savings.

A Quick "Should I Wait?" Checklist

The Bottom Line

Last-minute deals aren't random. They follow patterns. Once you understand them, waiting stops being a gamble and becomes a strategy.

How We Track Prices

Every week, we track more than 35,000 sailings. Each sailing generates multiple price snapshots, and we compare every new price against its recent average to see when something meaningful changes.

We use a 90-day trailing average because it filters out the noise. Cruise pricing wiggles constantly — a long window gives a much cleaner signal.

A real drop isn't a sale banner. It's a price that falls 5% or more below its 90-day trailing average.

Looking at prices this way shows:

• When cabins actually get cheaper
• How often lines adjust fares
• Which days real drops appear
• How pricing behaves across the booking window

This isn't guesswork. It's what we see across hundreds of thousands of price changes every week. You can explore current deals to see this in action.

This report will only get stronger as the dataset grows — and we'll continue publishing updated trends as we collect more history.

Final Takeaway

Cruise pricing looks complicated from the outside, but the rhythms are consistent. Once you understand the weekly cycle and the booking windows where prices move, everything gets easier.

Your Cruise Booking Cheat Sheet:

• Check prices on Saturdays
• Watch the 0–50 day window if you're flexible
• Use 51–100 days for the best mix of price and cabin choice
• Don't rely on 150+ days for deals
• Reprice if you book early

Most travelers book blindly. You don't have to.

With the data behind you — and a little timing — you can book confidently, skip the guesswork, and know you're getting a fair price without waiting for a miracle sale.
