You asked ChatGPT for five days in Kyoto and got back a tidy plan: temples in the morning, a market at lunch, a neighborhood to wander before dinner. It reads well, but can you travel on it?
ChatGPT is a good place to think a trip through and a weak place to keep the plan. It helps most before you have a destination. It helps least with opening hours, closures and availability, and with everything that happens to a plan after the first draft: changing one day, sharing it with the people coming, opening it at the station.
Aizzie is this site's product. ChatGPT details come from OpenAI's help center and announcements, its travel partners' announcements and the third-party research linked below, and Aizzie details from its product team, all checked on 16 September 2026.
In Future Partners' 2026 survey, ChatGPT was the AI tool American travelers most often used to plan travel. It is strongest on open questions: where to go, when, and what suits your group.
AI itineraries go wrong on details that change. In Greetwell's 2026 survey, 55% of travelers who had used AI for travel met at least one wrong recommendation, and 16% were pointed at something that did not exist.
A planning app's draft still needs checking, but the app ties places to map listings, lets you change one day at a time, and gives a group one itinerary to edit together.
Use ChatGPT to decide, and a planner to hold the plan once more than one person needs it.
If your plan is already at that stage, build it in Aizzie, where your group can edit one itinerary together.
More every year, mostly for the deciding part. Deloitte's 2026 summer travel survey put gen AI adoption for trip planning at 25%, up from 15% a year earlier (Deloitte).
Future Partners found 31.9% of American travelers used AI tools to help plan or prepare for a trip in the past 12 months, up from 22.6% in August 2025. Among respondents asked about specific tools, ChatGPT was the most common at 39.1%, ahead of Google Gemini at 30.3% (Future Partners, 2026).

Travelers are warier of letting AI book. In Expedia Group's research with YouGov, 66% said they would not trust an AI assistant to buy or book anything on their behalf, and 8% felt comfortable booking through an AI platform. The survey covered more than 5,700 adults in the US, UK and India in 2026 (Expedia Group).
Before a plan exists, ChatGPT can reason through the trade-offs with you: whether October or November suits a first trip to Japan, which Lisbon neighborhood works with a stroller, or how to split ten days between two cities. It also covers the jobs around a trip in the same window: a packing list, a message to a host, a menu translation.
Several features help with longer planning, according to OpenAI's help center and announcements and, for the travel apps, Expedia and Booking.com:
Memory. When enabled, ChatGPT remembers context from your chats, such as a dietary need or a travel style.
Projects. A project keeps a trip's chats, files and instructions together. Since October 2025, Free, Go, Plus and Pro users can share a project, with up to 5 collaborators on a Free plan.
Maps in search. On iOS and Android, search results can include a map when the answer calls for one.
Travel apps. Expedia and Booking.com have apps inside ChatGPT that show live places to stay, and Expedia's also shows flights and interactive maps. You finish the booking on the partner's own site, and availability depends on your region.
ChatGPT itself does not complete these flight and hotel bookings. In March 2026, OpenAI told Skift it was prioritizing search and product discovery, with checkout moving to apps (Skift).
The problems travelers report most often are wrong facts: prices, hours and availability. Greetwell surveyed 1,000 US leisure travelers in 2026. Among the 485 who had used or tried AI for travel, 55% met at least one recommendation that was inaccurate, unavailable, nonexistent, closed or otherwise wrong (Greetwell). The survey covers AI tools in general, not ChatGPT alone.

BBC Travel reported a couple who hiked Mount Misen in Japan for sunset on ChatGPT's advice: "ChatGPT said the last ropeway down was at 17:30, but in reality, the ropeway had already closed. So, we were stuck at the mountain top." The same piece quotes a Peruvian guide who met two tourists heading alone to a "Sacred Canyon of Humantay" that an AI tool had described. It does not exist (BBC Travel, 2025).
A Euronews journalist planned a Tallinn weekend mainly with ChatGPT. Each time she asked ChatGPT to narrow the food options, the itinerary "seemed to become worse and worse" (Euronews, 2025). In InsureMyTrip's review of a seven-day Switzerland itinerary, one restaurant ChatGPT suggested, Grigihütte, did not exist (Forbes, 2026).
A peer-reviewed study of ChatGPT itineraries with 1,004 participants found hallucinations lowered perceived accuracy, and through it trust and the intention to follow the itinerary (Journal of Consumer Behaviour, 2026). Civitatis surveyed more than 7,000 of its users and found nearly half of those who had planned with AI met incorrect or outdated details, most often opening hours, prices and availability (TravelDailyNews, 2026).
On TravelPlanner, an academic benchmark of 1,225 travel-planning tasks, GPT-4-Turbo, gathering the information with search tools itself, produced a plan meeting every constraint 0.6% of the time (Xie et al.). That was a 2024 model under a strict pass bar, so read it as a sign that budgets, dates and routing are hard to keep straight in one chat, not as a score for today's ChatGPT.
Every AI itinerary needs checking, including one Aizzie writes.
Places are map listings. Aizzie's place data comes from Google Maps. Each place in an itinerary maps to a Google Maps listing, and the place card shows its opening hours, rating and review count. You read the hours on the card instead of searching each name. Aizzie does not confirm a place is open on the day you arrive.
You change one day at a time. Aizzie drafts a day-by-day itinerary from a destination, your dates, a travel style and interests, plus any notes in an additional preferences field. Afterwards the copilot chat can regenerate a single day in place, and you can add places by hand, so a change to Tuesday leaves Wednesday alone.
Travel between stops is in the plan. Each leg shows the travel mode, time and distance, and you can switch between driving, transit, bicycle, two-wheeler and walking. The itinerary map shows every leg of the day, and a Directions link on each leg opens it in Google Maps. Ask the copilot chat to optimize the route and it reorders the stops.
Aizzie keeps working during the trip. It has a packing and to-do checklist. On mobile, checklist notifications, offline trips and geofencing reminders are available.
If the trip is to Japan or Korea, the apps to install for trains, taxis and payments once you land are in Japan travel apps and Korea travel apps.
ChatGPT can share the conversation around the plan. According to OpenAI's help center, group chats have been closed to new chats and new members since 9 July 2026, and existing ones are moving to read-only. A shared link shows a copy of the chat as it stood when the link was created or updated. In a shared project, collaborators work in the project's chats, files and instructions.
The itinerary itself is still a ChatGPT reply. When someone wants to swap a museum for a hike, they ask for a new version, and the group has to agree which version is current.
Aizzie shares the itinerary. Tripmates you invite edit the same trip in real time, with view and edit permissions set separately. They can co-edit in a browser without installing the app, though each needs an account, and co-editors can use the copilot chat on the shared trip.
You have not picked a destination yet. ChatGPT can talk through a choice between Hokkaido and Okinawa, or whether a trip fits your leave. Aizzie needs a destination and dates before it drafts a trip.
The trip is short and you are traveling alone. A two-night city break with one hotel does not need a shared itinerary. A ChatGPT reply checked against Google Maps may be enough.
You want to browse hotels and flights in the same chat. Where the Expedia and Booking.com apps are available, you can look at live options before booking on the partner's site.
Your preferences already live in ChatGPT. If memory and projects hold them, starting a trip there needs no setup.
Give exact dates, not a month. Opening days, seasons and events depend on them.
Describe the group. Ages, mobility, diets and how much walking a day. In InsureMyTrip's Switzerland review of ChatGPT, Gemini and Google AI Mode, several itineraries included physically demanding days unsuited to the two older travelers named in the prompt.
Set the pace. Say "relaxed, two main stops a day" rather than leaving it to the model.
Ask it to flag what to verify. Request a list of every hour, ticket, reservation and transfer time to confirm before booking.
Then check each place on Google Maps. When more than one person needs the plan, move it into a planner. Funliday imports a ChatGPT share link. Aizzie has no ChatGPT import and cannot read a pasted ChatGPT share link, so you start the trip from the destination and dates you settled on, then add the places you kept by hand or let Aizzie draft the days and compare.
It is good for deciding where to go, when, and what suits your group. It is unreliable on hours, closures and availability, which AI tools in general get wrong often: 55% of AI-using travelers in Greetwell's 2026 survey met at least one wrong recommendation. Treat a ChatGPT itinerary as a draft.
Not flights or hotels. Where the Expedia and Booking.com apps in ChatGPT are available, you browse options in the chat and finish the booking on the partner's site. Availability of the apps varies by region.
Yes. A shared link shows a copy of the conversation as it stood when you created or updated the link. A shared project lets collaborators, up to 5 on a Free plan, work in the project's chats and files. The itinerary stays a chat reply, so a group that edits one plan together is better served by real-time co-editing in a planner.
Check that every place exists and is open on your dates, using its Google Maps listing or official site. Then confirm tickets and reservations, prices, travel time between stops, and the last departure of any ropeway, ferry or train you rely on. Wrong prices, hours or details were the most common problem in Greetwell's survey, reported by 27% of AI users.
Use ChatGPT while the trip is still a question: where, when, how long, and what your group can manage. Use a planning app once there is a plan to keep, change and share.
If you travel alone on a short trip, ChatGPT plus a Google Maps check can be enough. If several people will edit the trip, or you will open it on the road without signal, put the plan in a planner (in Aizzie, offline access is in the mobile app). If you plan on Wanderlog, its AI assistant is powered by ChatGPT, per Wanderlog's own page, and Wanderlog alternatives: Aizzie vs Wanderlog covers that trade-off.
To keep the plan in a planner, draft it in Aizzie and invite the people coming.
