However, this convenience prompts a significant inquiry regarding the functionality of travel algorithms: “If AI solely learns from your established preferences, could it risk confining your vacations within a ‘filter bubble’?”
On social media platforms, recommendation engines function based on historical engagement metrics, presenting users with content similar to what they have previously clicked, watched, or liked. From a machine learning perspective, this heavily involves ‘exploitation’—using known historical preferences to optimize immediate satisfaction. The computer science community refers to this result as over-specialization.
A review of recommender systems published in the Journal of Computer Science and Technology (Springer) highlights that focusing solely on prediction accuracy ultimately ensnares users in predictable cycles. To combat this, computer scientists evaluate algorithm performance not just on accuracy, but also on “serendipity,” a criterion that deliberately balances relevance with an element of surprise.
In practice, algorithms typically navigate this balance through what engineers term ε-greedy policies. Rather than centering 100% of an itinerary on a user’s past selections, the system sets aside a calculated percentage for “exploration”—a strategic injection of randomness that tests new options without completely forsaking fundamental preferences. When travel platforms neglect to incorporate this balance, they risk trapping users in an echo chamber where someone who opts for a tranquil beach resort once may be continually steered toward identical quiet beaches, thereby filtering out unexpected mountain hikes or vibrant cultural festivals they never realized they desired.
The core dilemma in AI-driven travel revolves around balancing ‘exploitation’ with ‘exploration’ (introducing controlled randomness or deliberate novelty to allow room for serendipity in itineraries).
How Travel Platforms Are Engine-ing for Serendipity
Online Travel Agencies (OTAs) assert that the process of making travel decisions necessitates a distinct algorithmic framework compared to scrolling social media feeds. Rikant Pittie, CEO & Co-founder of EaseMyTrip, underscores that personalization should broaden consumer choices rather than restrict them.
“Personalization should never become a filter that limits discovery. While previous preferences enhance recommendations, travel fundamentally embodies exploration. AI should harmonize familiarity with inspiration by unveiling seasonal destinations, emerging experiences, and alternative itineraries that users may not have actively sought. The role of AI is not solely to predict preferences but also to expand them,” Pittie stated.
Pittie emphasizes that diversity and exploration need to be intentionally integrated into recommendations: “The most enriching travel experiences often arise from stumbling upon places that were not part of the initial plan. AI should be engineered to highlight a blend of popular spots alongside lesser-known alternatives, taking into account factors like seasonality, traveler interests, and changing trends. This strategy renders recommendations more dynamic while encouraging travelers to venture beyond the usual routes.”

Consumer interaction with AI during travel planning is also evolving. Instead of seeing AI as a static search bar, travelers are engaging with conversational LLMs (Large Language Models) to refine their plans and adjust while traveling.
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 utilize AI for travel planning.
“According to Agoda’s 2026 Travel Outlook Report, 68% of Indian travelers indicated they are likely to use AI for travel planning, and we are observing this trend emerge earlier in the journey, with travelers employing AI not just for bookings, but to explore where to go, compare choices, and create comprehensive itineraries. At Agoda, personalization can be influenced by what customers have previously searched for, booked, and engaged with, but the intent is not merely to replicate prior actions,” Khan remarked.
Khan adds that avoiding algorithmic predictability demands a balance between efficiency and spontaneous, real-time updates: “Well-implemented AI enhances travel planning relevance while still allowing for discovery. This balance holds importance because travel isn’t just a practical decision. Efficiency matters: travelers desire assistance in narrowing choices, comparing prices, and minimizing planning friction. However, if recommendations become overly narrow, they can undermine the excitement of travel.”
“We are also noticing that travelers expect more dynamic support as their journeys unfold. The value of AI is not limited to initial recommendations; it can also adapt to shifting contexts, such as weather, timing, location, or disruptions. This could mean suggesting an activity more suitable for the day, spotlighting a local dining option, or helping a traveler make quick adjustments to plans. When utilized correctly, AI can enhance travel planning’s personalized nature without it becoming predictable,” Khan continued.
How to Prompt AI for Serendipity: A Guide for Travelers
While travel platforms incorporate diversity into their recommendation systems, travelers using conversational AI tools can intentionally allow for surprise in their prompts:
Set an Explicit “Variance” Ratio: Rather than requesting a standard itinerary, specify a deliberate allocation. For instance: “Craft a 4-day Tokyo itinerary. Allocate 70% to visiting cafes and art galleries, but reserve 30% for local activities that I haven’t mentioned which a local might enjoy.”
Use Real-Time Context Over Static Profiles: Request suggestions from AI mid-trip based on your immediate environment rather than past habits. For example: “I am in Downtown Florence with 2 hours until dinner. Can you recommend an offbeat spot within walking distance?”
Prompt for Counter-Preferences: Encourage the algorithm to think outside its echo chamber. For instance: “Based on my preference for nature trips, suggest one high-energy cultural activity or local festival in this city that I wouldn’t usually choose, but might enjoy.”
Ultimately, AI travel tools perform best when viewed as collaborative sounding boards rather than rigid arbiters of choice. By merging predictive personalization with intentional prompt variation, travelers can benefit from automation’s speed while maintaining the spontaneous experiences that render travel unforgettable.
