Planning a trip with ChatGPT or Gemini can save hours of research, but these tools are best treated as drafting assistants rather than travel agencies. They excel at turning vague requests into structured plans, yet critical details like opening hours, final prices, and entry requirements still demand verification through official sources. A closer look reveals a significant gap between what these platforms advertise and what users in Spain can actually access.
- Drafting strength: Both chatbots excel at brainstorming, grouping activities by neighborhood, and generating packing lists or budget outlines.
- Availability gap: Several of Google’s most touted travel features, including the Gemini Spark agent and personalized intelligence, are unavailable in the European Economic Area, which excludes Spain.
- Verification imperative: OpenAI and Google both acknowledge that search results and citations can be incomplete, outdated, or incorrect, making official sources essential for visas, schedules, and pricing.
What Chatbots Actually Do Well
The real value of AI travel planning lies in three areas: initial ideation, logistical clustering, and tedious list-making. Google’s official blog, published in August 2026, explains that Gemini can create tailored routes and group activities by neighborhood. ChatGPT, meanwhile, leverages web search, which according to OpenAI’s help documentation is available across all plans as of November 2026, including the free tier and even without logging in. Responses can include source citations and, on iOS and Android, a map with results.
In practice, this means a prompt like “four days in Kyoto, low budget, no early mornings” can yield an organized plan that you then refine. The chatbot saves you searches, but it does not save you from checking.
The Availability Gap: What Works in Spain
The short answer is that in Spain you can use search and public data from maps, flights, and hotels, but not Google’s personal agents or several of its booking and activity apps.
Gemini’s Limitations
According to Google’s help pages, Gemini automatically uses public information from Google Search, Google Flights, Google Hotels, Google Maps, and YouTube. For Flights, Hotels, Maps, and YouTube, you need the “Save activity” setting enabled; Search works even when it is off.
Gemini Spark, the agent that can open Chrome, search for flights, and fill in bookings so you only press the final button, requires a Google AI Pro or Ultra plan, users over 18, and, as of November 2026, operates wherever Gemini is available except the European Economic Area, Nigeria, the UK, and Switzerland. Spain is excluded.
Personalized intelligence, which lets Gemini read your flight confirmations in Gmail or your photos to refine suggestions, is also unavailable in the EEA as of November 2026. Activity apps Viator and GetYourGuide only work in the US and in English, while OpenTable is limited to the US and UK, also in English.
ChatGPT’s Constraints
As of November 2026, ChatGPT’s restaurant table search shows availability from OpenTable globally, Resy in the US only, and Yelp in the US and Canada. It works on consumer plans with certain models, not in voice mode, and ChatGPT does not save, modify, or cancel reservations. The former ChatGPT agent mode, which browsed websites and completed tasks, is no longer available; OpenAI now points users to ChatGPT Work and Codex for long multi-step tasks, and to ChatGPT’s cloud browser for compatible navigation flows.
OpenAI warns on its help page about the risk of “prompt injection”: malicious content on a website that attempts to trick the agent.
Where AI Fails: Schedules, Prices, Closures, and Paperwork
AI fails precisely on data that changes: an opening hour, a price, or an entry rule may have shifted since the page the chatbot drew from was published. This is not speculation. OpenAI writes that search results and citations may be incomplete, outdated, or incorrect, and recommends opening the cited source, checking its publication date, and consulting an official source when accuracy matters. Google warns that its apps can make mistakes and asks users to verify responses.
Even Gemini’s reliance on Google Maps is no guarantee that a venue is open. Google Maps help explains that users can submit suggestions to help Maps decide whether to change a location’s status (temporarily closed, permanently closed, moved) and that business owners can edit their information. The data is only as fresh as the last person who updated it.
The most delicate case is entry requirements. For example, to travel to the UK as a tourist with a European passport, you typically need an electronic travel authorization (ETA) rather than a visa. According to gov.uk, as of November 2026 it costs 20 pounds (about 24 euros at the ECB reference rate of November 6, 2026), allows stays of up to 6 months, is required for every traveler, including infants, and the UK government warns that other websites may charge more to process it. If a chatbot gets that wrong, you are the one facing the problem at the airport.
How to Verify What Matters Before Booking
Make the plan with AI and verify with official sources, in this order:
- Travel advisories from the Ministry of Foreign Affairs. The official travel recommendations page has a file for each country. The Ministry clarifies that these are not binding, that travel is at the traveler’s own risk, and that Social Security does not cover you abroad except in certain EU and EEA countries with the European Health Insurance Card. It recommends insurance covering any eventuality.
- Traveler Registry. The Ministry recommends registering before departure to facilitate assistance in emergencies.
- Official websites of the destination country for visas and authorizations, such as gov.uk for the UK. Never through intermediaries.
- The venue’s own website for hours, closures, and entry prices. If the chatbot cites a source, open it and check the date.
- The final price, at the payment gateway. The AI’s budget is indicative. And if you pay outside the eurozone, review why it is almost always better to choose the local currency when paying by card.
A useful trick: ask the chatbot to link the official page for each schedule or requirement. It is not foolproof, but it gives you a list of what to open.
AI is already a good companion for the creative side of a trip and a poor notary for the bureaucratic side. What stands out most is the gap between showcase and availability: Google’s agent that books for you, the reading of your Gmail confirmations, and the excursion apps are presented as the future of planning, but from Spain they cannot be used today. Meanwhile, the practical rule is simple: an itinerary can be written by a machine; the visa, the schedule, and the price are signed by an official source.
