I asked ChatGPT to plan a luxury seven-day trip to Switzerland for four adults, including two travellers aged over 60. It produced a smooth, logical route through the country's major destinations, with luxury at the forefront. But several of its recommendations were incorrect or misleading: one restaurant it recommended, Grigihütte, does not exist; Michelin ratings were misrepresented; pricing for major experiences was underestimated; and several days in the itinerary were too physically demanding for older travellers.

Expert: Sara Boisvert, Director of Marketing, InsureMyTrip Travel insurance company InsureMyTrip tested three large language models - ChatGPT, Gemini and Google's AI Mode - by asking each to plan a luxury seven-day trip to Switzerland for four adults, including two travellers aged 60 and over. The itineraries were assessed on accuracy, pacing, pricing realism, sourcing and total travel time. The ChatGPT itinerary looked excellent on the surface but was riddled with detail errors. A restaurant called Grigihütte that the AI recommended does not actually exist. Michelin ratings were misrepresented, with restaurants presented as more highly rated than they really are. Prices for major experiences were underestimated, leaving the budget unrealistic. Several days included physically demanding activities that were clearly unsuited to older travellers - the kind of mistake that matters when planning for a group with mobility or endurance limits. Sara Boisvert, director of marketing at InsureMyTrip, said: 'The analysis found that they can be useful to provide a well-structured itinerary, but, when we reviewed the details more closely, inaccuracies began to appear.' She added: 'The itineraries often looked polished and logical on the surface, which could make them feel reliable at first glance. However, closer inspection revealed that both big and small details were wrong.' The takeaway: AI models are useful for structuring a rough trip outline, but every hotel, restaurant, rating and price must be verified against authoritative sources before booking - and traveller constraints such as age and mobility have to be checked by a human.

Asked to plan trips, AI chatbots sent travelers to places that do not exist. Among the 485 U.S. leisure travelers in the Greetwell AI Travel Survey 2026 who had used or tried AI for travel, 55% hit at least one recommendation that was inaccurate, unavailable, nonexistent, closed or otherwise wrong. Broken down: 27% got incorrect prices, hours or other details; 21% were pointed to something fully booked or unavailable; 17% got something simply wrong for what they asked; 16% were sent to a place, tour or activity that did not exist; and 10% were recommended a business that was permanently closed.
Asked to cancel only the outbound leg of a round-trip SkyMiles award between New York JFK and Los Angeles while keeping the return, Delta Concierge told the passenger in writing: "Your JFK to LAX flight has been canceled, and your LAX to JFK flight remains booked." Delta's own refund confirmation shows the opposite: all 32,400 miles were redeposited and the full $11.20 in taxes refunded, with both DL752 (JFK-LAX) and DL938 (LAX-JFK) listed as canceled - the receipt even displayed "Refund Number: null". The AI confirmed an itinerary state that Delta's ticketing system had already destroyed, and Delta Reservations then told the passenger the original award could not be restored and that a replacement one-way would cost nearly twice as many miles.
A passenger asked United Airlines' customer-service chatbot how long she had to use a $200 United travel credit before it expired. The chatbot answered that the money would stay available for years. A screenshot of the exchange shows the bot stating that her $200 TravelBank credit "stays active for 5 years from the date it's deposited." The passenger, Alison Gil, planned around that answer and held the credit for a larger trip. A few weeks later United emailed her to warn that the same $200 in TravelBank cash would expire on September 27, 2026 - roughly one year after it was deposited, not five. When she questioned the discrepancy, she says United told her: "sorry, the bot told you that, but it's one year and we can't change it." The airline later acknowledged to NBC 5 Responds that its "AI chatbot provided this customer with the wrong information for her situation," while noting the disclaimer customers are shown saying information "may not always be complete or relevant."
