Using AI to Plan a Trip: An Honest Test of What Actually Works

AI travel planning is either the future or a confident liar, depending on who you ask. I tested it properly — with no app to sell you and no affiliate link waiting at the end.

Using AI to plan a trip is now the majority behavior, not the experiment. Adoption figures vary by study — but the most rigorous recent one, Phocuswright’s March 2026 research found 56% of US leisure travelers used AI for at least one trip in the past twelve months — up from 43% just nine months earlier, the fastest behavioral shift they’ve measured in over a decade. In other words, this stopped being a novelty question a while ago. The real question is different: should you trust it?

Before I answer, one thing worth knowing about who’s answering. Almost every article on this topic is written by someone with skin in the game — either an affiliate roundup funneling you toward “the 7 best AI trip planners” (each link paying commission), or a travel-tech company explaining that ChatGPT has limits and, conveniently, their app doesn’t. I have neither. Instead, I write destination guides based on places I’ve actually been, and I wanted to know honestly whether AI trip planning helps or quietly wastes your time. That’s the whole test.

01 — Can AI Actually Plan a Trip?

Yes — and also no, in a way that matters. AI can produce a seven-day itinerary in thirty seconds that looks better than what most travel agents would hand you after a week. The structure will be logical, the pacing plausible, the writing clean. What it cannot do reliably is guarantee that anything inside that beautiful structure is true.

That distinction is the entire subject of this post. Consequently, the honest headline verdict is this: AI trip planning is a genuinely excellent research process and an untrustworthy booking process. It will save you hours in the thinking stage and cost you dearly if you let it near the booking stage unsupervised. Everything below is just the detail of where that line sits.

02 — What AI Genuinely Does Well for Travel Planning

Let’s be fair first, because the strengths are real. Anyone telling you AI is useless for planning a trip — that using AI to plan a trip is a waste of time — hasn’t used it properly, or is selling you something older.

Ideation and destination research

This is the strongest use case by a distance. When you don’t yet know where you’re going, AI is a superb sparring partner. Feed it your constraints — season, budget, how you travel, what bored you last time — and it will surface options faster than any listicle. Moreover, it handles the comparative stage well: “Montenegro or Albania in June for a first solo trip” gets you a genuinely useful trade-off analysis, not a sponsored answer.

The reason is simple. At this stage, nothing needs to be current. General truths about a country — its geography, its seasons, its character — change slowly, and that’s exactly the kind of knowledge these models hold well.

Nuanced, specific questions generic guides can’t answer

Here’s where AI beats the standard travel internet outright. Questions like “which Lisbon neighborhood is walkable, quiet at night, and near good restaurants for someone traveling with a toddler” have no dedicated blog post — the combination is too specific. Generic top-10 lists can’t help you. AI, on the other hand, can synthesize across everything it knows and give you a reasoned, personalized answer in seconds.

Similarly, it’s strong on the awkward practical questions people rarely write articles about: unusual visa combinations, whether your rail pass covers a specific border crossing, how tipping actually works in a country where the guidebooks contradict each other. The answers still need verifying — but as a starting point, nothing else comes close.

First drafts, structure, and packing lists

Additionally, AI is very good at the unglamorous scaffolding of a trip: a first-draft day-by-day structure, a packing list adjusted for your season and airline’s luggage rules, a rough budget framework. None of this is creative work. All of it used to eat an evening. Now it takes minutes, and the draft is good enough that your job shifts from writing to editing — which is a much better use of your judgment.

03 — What AI Gets Wrong When Planning a Trip

It invents hotels, restaurants, and opening hours

This is the big one, and it has a name: hallucination. When you’re using AI to plan a trip, the model doesn’t retrieve facts from a database — it generates plausible-sounding text. Usually that text is accurate. Sometimes, however, it’s a complete fabrication delivered in exactly the same confident tone, and travel is full of the small, specific, changeable facts these models fabricate most: restaurant names, hotel recommendations, opening hours, entry fees.

The evidence isn’t anecdotal. In early 2026, researchers at travel insurer InsureMyTrip tested ChatGPT, Gemini, and Google’s AI Mode on the same task — a luxury seven-day Switzerland itinerary — and reviewed every detail. The plans looked polished. Underneath, some recommended restaurants didn’t exist at all, pricing for major experiences was significantly underestimated, and the itineraries confidently included details that were simply wrong. The researchers’ most telling observation was about tone: the itineraries appeared just as confident when the details were incorrect.

I ran two of the prompts below against Porto — a city I’ve covered in a verified, walked-in-person guide — to see how it held up against something I could actually check. The timing prompt (September trade-offs) was genuinely good: accurate on weather, crowd patterns, the Douro harvest window, and the São João miss. The hidden-costs prompt was even stronger — it surfaced the couvert trap, the Livraria Lello entry fee, and the Andante card confusion at the airport, all real and all things a first-timer would walk into. Where it slipped was subtler: the tourist tax figure it cited as “€2 per person per night” is outdated — Porto raised it to €3 in 2024, and the old winter exemption it mentioned no longer exists. Accurate-sounding, confidently stated, and wrong by enough to matter at checkout. That’s the pattern exactly.

For contrast: this is what a verified, walked-in-person Porto itinerary looks like — every place in it exists, because I stood in front of it. That’s the standard AI output has to be checked against, not the standard it meets.

It can’t be trusted on live prices or what’s still open

Furthermore, even when a place is real, the details attached to it are often stale. Most general chatbots work primarily from training data with a cutoff date, sometimes supplemented by web search that may or may not fire when you need it. Prices drift upward, restaurants close, timetables change seasonally — and the AI keeps serving the 2024 version of reality with 2026 confidence. A price quoted by a chatbot is not information; it’s a rumor with good formatting.

It recommends the same places as everyone else

Finally, the quieter failure: ask AI for “underrated spots” in any major city and you’ll receive the same fifteen suggestions every travel blog published three years ago — usually wearing the phrase “hidden gem,” which at this point functions as a watermark for recycled content. The model was trained on the travel internet, so it reproduces the travel internet’s consensus. That’s fine for a first pass. It is not local knowledge, and it never will be. If you want places chosen by an actual person with actual taste, you still need actual people — a genuinely curated list reads differently from a statistical average, and you can feel it.

04 — Using AI to Plan a Trip: The Accuracy Problem

So how accurate is AI travel planning, really? The Switzerland study gives the clearest measured answer we have. Beyond the invented restaurants, the researchers found pricing errors that weren’t rounding mistakes but category errors: a Jungfraujoch train journey listed at roughly $129–$258 when actual fares start around $342. Anyone budgeting from that itinerary would arrive in Switzerland — of all places — meaningfully short of money. On top of that, hotel availability went unverified, sourcing was thin, and one model skipped the Swiss Travel Pass entirely, a basic tool any human planner would mention.

The phrase that best summarizes the findings is one I’d put on a warning label: polished but wrong. These errors don’t look like errors. They look like the rest of the itinerary.

Interestingly, travelers seem to sense this. Phocuswright’s same 2026 research found that only 8% of AI users considered AI answers sufficient on their own — half still clicked through to source websites to verify before acting. That instinct is exactly right. Trust in AI travel planning should have a ceiling, and the crowd has priced that ceiling correctly.

05 — Can You Use AI to Find Flight Deals?

Mostly no — and this is the area where the gap between what people expect and what AI delivers is widest. General chatbots cannot see live airfares. When one quotes you a fare, it’s recalling old training data or loosely summarizing a web result, and either way you should treat the number as decoration. Flight pricing changes hourly; a language model is structurally the wrong tool for it.

That said, AI does help around the edges of flight planning. It’s genuinely useful for strategy: which nearby airports are worth checking, whether an open-jaw routing makes sense for your itinerary, what a realistic price benchmark for a route looks like so you can recognize a deal when a real search engine shows you one. In short — when using AI to plan a trip, let it shape the search strategy, then run the actual fare search on Google Flights, Skyscanner, or the airline directly. Never the other way around.

06 — 10 Travel-Planning Prompts That Actually Work

Here’s the honest point almost nobody makes: the difference between AI giving you generic listicle sludge and something genuinely useful is almost entirely the prompt. Ask lazily, get the average of the internet. In contrast, ask precisely — with your constraints, your dates, and explicit permission to be negative — and the output improves dramatically.

These ten are the prompts I’d actually use, written to be copied as-is. Replace every [bracket] with your specifics. They’re deliberately model-agnostic — they work the same in ChatGPT, Claude, or Gemini. And one rule stands over all of them: treat every specific detail the AI returns as unverified until you’ve checked it yourself.

Prompts for choosing where to go

Prompts for building the plan

Prompts for catching AI’s mistakes

These last two matter most, and no affiliate roundup will hand them to you — because they’re prompts that make the AI undermine its own output. Run them every time.

07 — So How Should You Actually Be Using AI to Plan a Trip?

After all of the above, the practical answer fits in a short set of rules. Using AI to plan a trip works when you assign it the right job and refuse to promote it beyond that job.

• Use it early, not late: ideation, comparison, and structure are its territory. Bookings are not.
• Give it your constraints: vague prompts return the internet’s average. Specific prompts return something like advice.
• Invite negativity explicitly: “be skeptical,” “tell me the downside,” “who would hate this” — without permission, AI defaults to brochure mode.
• Verify every proper noun: any hotel, restaurant, price, or opening time gets checked against an official source or a real recent review before you rely on it. No exceptions.
• Never book on its word alone: money moves only after a human — you — has confirmed the thing exists at the price claimed.

Follow those five and using AI to plan a trip becomes what it genuinely is: the best research process travel planning has ever had. Skip them and you’re budgeting for Switzerland with numbers someone made up — and finding a place like Antalya honestly worth visiting, or not, is still a judgment call no model can make for you, because judgment requires having stood there.
