Big spenders are hiding in plain sight, and lines can leverage data they already own to influence everything from margins to ship design.
Cruise lines’ commercial teams are laying out 2027-28 itineraries: where the ships go, how cabins are priced, and which ports receive marketing spend. Very little planning answers a more valuable question of identifying the high rollers. Of the guests already booked, which ones will spend two, three, or five times the average once they are aboard?
The honest answer, at many cruise lines, is nothing. High-yield guests are identified from the receipts they leave behind. By that time, the voyage is over, and the relationship resets to zero.
AI-driven scoring models can leverage available information to create planning tools already prevalent in the airline and casino industries.
Onboard revenue has expanded to a third of total sales at major operators. The industry has openly moved to a model of attracting guests with competitive fares and increasing use once the voyage begins.
The story that matters: a minority of guests drives a disproportionate share of the spend, and that key group can be identified earlier than most lines admit.
Focus on the booking, not the birthday
Most cruise segmentation still leans on demographics and loyalty tier: age, household, cabin category, past sailings. These are fine for brochure design, but weak for prediction. Two 52-year-old couples in identical balcony cabins can behave differently onboard, and the line usually cannot tell them apart until their folios diverge on night three.
Yet the behavioral signals are already sitting in the reservation system, and one operator just quantified the scale. Royal Caribbean reported that nearly half of onboard revenue in fiscal 2025 was booked before guests even boarded, and 90% was made through digital channels. Half the onboard prize is now decided during the booking window, in a channel with clear visibility.
Pre-cruise purchase is the strongest available predictor of what a guest will do next. Carnival has found that every dollar of pre-cruise spending is worth an incremental 70 cents in onboard spending. A guest who, months before sailing, books a beverage package, reserves two specialty dinners, buys the premium Wi-Fi tier, and pre-books a shore excursion tells the operator exactly who they are.
The packages themselves keep getting bigger and more revealing: For example, Princess now prices its Premier and Plus bundles at roughly $100 and $65 per person per day, with the cruise fare increasingly resembling a nightly rate with add-ons layered on top, and which tier a guest chooses, and when, is one more signal sitting in the booking record. Every one of these choices is captured today. Most are not scored, and they trigger nothing.
The raw material is unusually rich. Princess and Carnival built the OceanMedallion, a wearable that runs off thousands of onboard sensors and updates a guest's preferences in real time; the platform's own architect previously built Disney's MagicBand and FastPass. MSC Cruises has its MSC for Me wristband and app; Disney Cruise Line runs DisneyBand+.
Adjacent industries already do this, with less data
The industry has spent a decade instrumenting the guest more thoroughly than on the casino floor or an airline cabin. However, little of it is pointed at spotting value before the guest ever boards. Two comparisons should be uncomfortable for cruise operators.
Airlines monetize a smaller prize with better machinery. Ancillary revenue reached 15.7% of global airline revenue in 2025, roughly half the cruise onboard share. Yet airlines have built New Distribution Capability and offer-management engines to price and target add-ons by customer and context, surfacing the right offer at the moment of need rather than as a generic upsell. Five U.S. carriers now take more than half their revenue from ancillaries. The real lesson is the posture: treat the add-on as the product and engineer the offer around the individual.
Casinos score value before the guest arrives. A casino rates players on frequency, bet size, and ancillary behavior, assigns high-value players to a named host, and routes early churn signals into automated retention flows before the player disengages. In online gaming, operators segment based on what players do, deposit shifts, game-preference changes, and session trends. They re-segment continuously so a guest drifting toward churn is caught while intervention still works. The cruise line has the same captive multi-day window as a casino resort, plus a booking lead time casinos would envy, and largely lets it sit idle.
Put the two models side by side against current cruise practice, and the gap is not subtle.

How casinos and airlines run it |
How most cruise lines run it today |
|---|---|---|

When value is scored |
Before arrival. Casinos rate players and assign hosts pre-trip; airlines price offers at search and booking. |
After embarkation, if at all. Value is inferred from spend as it happens onboard. |
|
Primary signal used |
Behavior: play frequency, bet size, ancillary attach, redemption patterns. |
Demographics and loyalty tier: age, cabin category, past sailings. |
|
Intervention window |
Weeks of pre-arrival contact plus the visit itself. |
Largely the 3-7 nights onboard, once the guest is a captive audience. |
|
Who owns the guest |
A named host or automated retention flow tied to a value tier. |
The ship. Handoff from booking to sailing is mostly anonymous. |

Ancillary share of revenue |
Airlines: 15.7% of global revenue (2025). |
Cruise: roughly 30-35% of revenue, a larger prize with less targeting. |
What a pre-embarkation scoring model actually does
An AI-powered scoring model built entirely on data the cruise line already owns and wired to actions it can already take can include four components:
- Score: Build a pre-embarkation value score from booking behavior and add-on history: fare and cabin path, pre-cruise package and excursion attach, upgrade timing, group linkage, and prior-sailing onboard folios where they exist. A machine learning model, not a fixed rules table, is what makes it practical to weigh dozens of these signals against each other at fleet scale — including weighting pre-cruise spend heavily, given its established 70-cent pull-through.
- Route: Send high-potential guests into targeted retention tracks before boarding, the cruise version of assigning a casino host. Use curated pre-cruise offers, a concierge or dining outreach, and an itinerary of experiences matched to revealed preference, not a blanket promotional blast.
- Convert: Capture spend earlier, when the guest is planning and most receptive, rather than competing for their attention against free options such as tanning on the pool deck. Pre-cruise conversion is higher-margin and, per the pull-through data, compounds onboard.
- Learn: Feed each voyage's actual pending onboard sales data back into the model so it retrains and sharpens with each sailing, the way many iGaming operators re-segment continuously rather than annually.
The so-what
Three commercial consequences follow:
- Revenue timing and mix improve. Shifting even a portion of onboard spend into higher-margin pre-cruise channels lifts yield per guest and pulls cash forward. On a large onboard revenue base, small shifts in attachment and pre-cruise conversion are material to EBITDA.
- Retention receives a head start. Identifying high-value guests before they board turns an anonymous booking-to-sailing handoff into a managed relationship and creates an intent to return that is set before the first voyage ends.
- Marketing spend is targeted. Scoring tells commercial teams which booked guests deserve concierge-grade attention and which do not, so pre-cruise effort follows expected value instead of loyalty tier or spray-and-pray promotion.
The planning window for 2027-28 is open now. Itinerary and pricing decisions taken this summer set the guest mix that will sail two years out. Building the scoring capability alongside those decisions, rather than after, means planning who is on the ship and what they're worth — not just where it goes.
