AI-Powered Personalization
Utilizing this to create optimized travel plans is changing the game for itinerary aggregation as AI brings intelligence and human-centricity to travel planning. Apps and services such as Google Trips, Hopper and Kayak scrape users’ browsing histories, past bookings and expressed preferences to generate personalized recommendations.

Additionally, AI can create itineraries that continually adapt to changing user needs and preferences, helping to eliminate the discovery and planning fatigue that can so often accompany travel booking, whilst also driving continued user engagement with the travel platform.
Influencer-Led Travel Planning
With social media now a key influencer in what trips are chosen, itinerary aggregators are now targeting themselves to have influencer content included in travel planning arms. TripIt and Sygic Travel harness influencer-city guides, so users can follow already air-tested travel itineraries.

The automation level at which this occurs guarantees optimized, real-time recommendations for travelers, increased customer satisfaction, and lower disruption, all at a fraction of the cost of existing solutions.
User-Generated Content and Community-Driven Travel
Itineraries are also increasingly influenced by user-generated content (UGC), with travelers trusting peer reviews more than traditional marketing. Tools like Komoot and Google Travel incorporate user-generated travel stories, enabling actual travelers to perform their own persona-based narratives through photos, videos, and prose guides.
Hashtags including #MyPerfectTrip and WanderlustItinerary produce millions of posts on Instagram and TikTok, influencing travel decisions and shaping demand for destinations. Aggregators use AI-powered tools like CrowdRiff and TINT to discover and analyze high-performing UGC, and turn that relevant content into real-time travel recommendations.
Aggregators still allow you to vote on itineraries, customize shared travel plans, and more, putting the planning process in the hands of the community. Itinerary aggregators leverage social validation and peer recommendations to establish credibility and drive user engagement.
