Google's AI Ultra subscription includes Spark, an always‑on AI agent that can create personalized travel plans using data from a user's Google accounts. In a test, the agent produced a detailed itinerary for a family trip to Hershey, Pennsylvania, scheduled for July 17‑19, 2026.

Planning a trip has been cited as a common demonstration of AI capabilities, but previous services typically offered only generic suggestions. Spark leverages Google's Personal Intelligence feature, which aggregates email, calendar, search history and other information to tailor recommendations.

The itinerary included driving directions, hotel options with pet fees, dog‑friendly activities, restaurant suggestions that accommodated the wife's onion‑free diet, and scheduled events such as a concert on Saturday night and a nap time for the three‑year‑old child. Spark identified the family members by name, used ticket information from an email, and adjusted lodging recommendations after the user noted his parents would be visiting. When asked to book an Airbnb, the agent prompted for permission to interact with external sites, attempted to access Airbnb, and was blocked by authentication policies, offering instead a list of available properties.

The experience illustrates how extensive personal data can enhance AI usefulness while raising concerns about privacy and surveillance, as the system used details such as children's names, ages and dietary restrictions without explicit user input.
