However, this convenience sparks a crucial question regarding travel algorithms: “If AI exclusively learns from your existing preferences, could it risk creating a ‘filter bubble’ around your vacations?”
Similar to social media platforms, recommendation engines rely on historical engagement data, displaying users more of what they have previously clicked, watched, or liked. In machine learning terms, this approach heavily leans on ‘exploitation’ (utilizing known historical preferences to enhance immediate satisfaction). Computer science literature labels this outcome as over-specialization.
A systematic review of recommender systems published in the Journal of Computer Science and Technology (Springer) indicates that an emphasis on mere prediction accuracy ultimately ensnares users in predictable cycles. To counteract this, computer scientists evaluate algorithm quality not just by accuracy but also by “serendipity,” a metric that intentionally balances relevance with an element of surprise.
In practice, algorithms often implement strategies referred to as ε-greedy policies. Rather than deriving 100% of an itinerary from a user’s historical clicks, the system allocates a determined percentage strictly for “exploration”—a deliberate injection of randomness that allows the system to introduce novel options without completely deviating from core preferences. If travel platforms neglect to incorporate this balance, they risk forming a travel echo chamber where a user who books a tranquil beach resort might be subtly directed toward identical quiet beaches indefinitely, excluding unexpected mountain hikes or lively cultural festivals they never realized they desired.
The core tension in AI-driven travel is rooted in balancing ‘exploitation’ with ‘exploration’ (incorporating controlled randomness or intentional novelty so that the itinerary allows room for serendipity).
How Travel Platforms Are Engine-ing for Serendipity
Online Travel Agencies (OTAs) suggest that travel decision-making requires a different algorithmic framework compared to scrolling through social media feeds. Rikant Pittie, CEO & Co-founder of EaseMyTrip, asserts that personalization should broaden consumer choices rather than restrict them.
“Personalization should never become a filter that limits discovery. While previous preferences assist in making recommendations more relevant, travel is inherently about exploration. AI ought to balance familiarity with inspiration by showcasing seasonal destinations, emerging experiences, and alternative itineraries that users might not have actively sought. The role of AI transcends merely predicting preferences; it should also expand them,” stated Pittie.
Pittie emphasizes that diversity and exploration must be intentionally integrated into recommendations: “The most enriching travel experiences frequently arise from discovering places that weren’t part of the original itinerary. AI should be programmed to highlight a blend of popular locations alongside hidden gems based on factors such as seasonality, traveler interests, and evolving trends. This approach renders recommendations more dynamic while motivating travelers to venture beyond traditional choices.”

The way consumers engage with AI during travel planning is evolving. Rather than perceiving AI as a fixed search tool, travelers now employ conversational LLMs (Large Language Models) to refine plans and make adjustments mid-trip.
Ahmer Khan, Senior Director of Marketing at Agoda, notes that according to Agoda’s 2026 Travel Outlook Report, 68% of Indian travelers are likely to leverage AI for travel planning.
“According to Agoda’s 2026 Travel Outlook Report, 68% of Indian travelers indicated they are inclined to use AI for travel planning, and we are observing this trend emerge earlier in the journey, with travelers utilizing AI not merely for bookings but also to explore potential destinations, compare options, and create comprehensive itineraries. At Agoda, personalization can draw on previous customer searches, bookings, and interactions, but the aim is not simply to replicate what a traveler has done prior,” Khan remarked.
Khan highlights that avoiding algorithmic predictability necessitates finding the balance between efficiency and spontaneous real-time updates: “Well-executed AI enhances travel planning by making it more relevant while still allowing for discovery. This equilibrium is crucial since travel is not solely a functional decision. Efficiency is essential: travelers seek assistance in narrowing choices, comparing prices, and minimizing planning fatigue. Yet, if recommendations become overly constricted, they risk diminishing the thrill of travel.”
“We are also witnessing travelers expecting more adaptive support as their trips progress. The value of AI extends beyond initial recommendations; it can adjust to evolving contexts, such as weather, timing, location, or disruptions. This may involve suggesting a more suitable activity for the day, pinpointing a local dining option, or aiding a traveler in swiftly altering plans. When utilized effectively, AI can enhance travel planning to be more personalized without rendering it predictable,” Khan added.
How to Prompt AI for Serendipity: A Guide for Travelers
While travel platforms incorporate diversity into their recommendation systems, travelers employing conversational AI tools can actively encourage surprise in their prompts:
Set an Explicit “Variance” Ratio: Rather than requesting a standard itinerary, outline an intentional distribution. For example: “Create a 4-day Tokyo itinerary. Allocate 70% for exploring cafes and art galleries, but reserve 30% for neighborhood activities I haven’t mentioned that a local would recommend.”
Use Real-Time Context Over Static Profiles: Request AI for mid-trip suggestions based on current surroundings instead of historical habits. For example: “I am in Downtown Florence, and I have 2 hours before dinner. Recommend an offbeat spot within walking distance.”
Prompt for Counter-Preferences: Encourage the algorithm to step outside its echo chamber. For example: “Given my preference for nature trips, suggest one high-energy cultural activity or local festival in this city that I wouldn’t typically choose, but might enjoy.”
Ultimately, AI travel tools are most effective when regarded as collaborative partners rather than rigid decision-makers. By merging predictive personalization with intentional prompt variation, travelers can enjoy the benefits of automation while still savoring the unplanned moments that make travel unforgettable.
