How to Check an AI-Built Itinerary Before You Sell It

Checked 20 Oct 2026Product details from Google, Skift, Engadget and OpenAI. Failure cases as reported by Stacker.

More clients now turn up with a day-by-day plan from ChatGPT, Gemini or a trip-planning app. That is mostly good news for an agent. The client has already told you the pace they want, the places they’ve heard of and roughly what they expect to spend. The trouble is that these plans read well. They are tidy, confident and specific, and the mistakes in them are the kind that only show up on the ground: a coach that can’t do the distance in the time, a boat trip that doesn’t run in that month, an entry rule that changed six weeks ago.

What AI can book in October 2026

Booking inside an AI chat has arrived, but only for a narrow slice of travel and mostly in the US. This is where the main products stand:

What none of them books is the ground work a group trip runs on: an airport meet-and-greet tied to a flight that lands late, seat-in-coach transfers on fixed pickup windows, a coach and guide across the Singapore to Malaysia border, a rooming list for 40, Jain meals in Pattaya on a Sunday night, or a MICE programme with venue holds and food and beverage minimums. Our portal team looked at the Google launch in more detail on the DMC Quote blog.

Real cases where AI got it wrong

All of these were reported publicly. None of them is exotic. Each one is a check an experienced agent would have run without thinking.

Seven checks before you quote an AI itinerary

Work through a client’s AI plan in this order. The examples are from Singapore, Malaysia and Thailand, but the same checks work anywhere.

1. Distances and drive times AI treats anything on the same map as reachable. Kuala Lumpur to Penang is around four hours each way by road, so “Penang day trip from KL” is two days of coach with an hour of sightseeing. Plot every day and add the road time.
2. Border crossings Route planners give driving time. They don’t add the checkpoints. Singapore to Kuala Lumpur by coach is five to six hours on a normal weekday because everyone gets off twice, and Friday evenings or holidays add more.
3. Opening days and seasons Attractions close for maintenance, public holidays change hours, and island boat trips off Phuket and Krabi are often cancelled in the May to October monsoon. Check the month, not just the place.
4. The arrival day Many overnight flights land early in the morning, and hotel check-in is usually 3pm. A plan that starts sightseeing at 9am with the luggage still on the coach needs early check-in or a gentler first day.
5. Entry rules, with dates Thailand cut its visa-free stay from 60 to 30 days for many nationalities on 15 September 2026, and plenty of AI answers still say 60. Visa rules differ by passport, so check each traveller’s nationality, not just the destination. All three countries need an online arrival card in a short window before entry. See what the Thailand change means for bookings.
6. Transfers between every stop AI lists places. It rarely says how the group gets between them. Every gap is a transfer to cost: SIC on fixed pickup windows, or private at a higher price but on the group’s own timing.
7. Real prices AI quotes public prices scraped from web pages, often out of date. Your cost is the net rate, and group pricing depends on coach size, guides and meals. A plan that looks affordable at retail prices can look different once it is costed properly, in either direction.

Where AI helps, and where it doesn’t

AI tools are good at the parts of the job that are about words: a first draft of a day plan, a description of a hotel area, a comparison of two islands, a client email in another language. They are weak at anything that depends on today’s facts or on how things actually run: entry rules, live prices, availability, and anything that involves a border or a group.

Our view is that a client who arrives with an AI plan is a better-briefed client, and that works in the agent’s favour as long as somebody checks the plan before money changes hands. That check is ordinary DMC work. For a classic three-country circuit, see how we put together a Singapore, Malaysia and Thailand trip.
