Which AI Is Best for Travel Planning? 2026 Study

Planning a trip used to mean hours across airline sites, hotel listings and review pages. AI chatbots now promise to do it in one conversation, from a full itinerary to the cheapest flight. To find out which AI is best for travel planning, our research team ran a head-to-head study from September 24 to October 13, 2026.

We gave the same 440 travel requests to seven AI platforms, producing 3,080 answers. The requests covered eight travel tasks, with 55 requests each, for destinations across the United States, Europe, Asia and Latin America. A panel of four professional travel advisors scored each answer from 0 to 100. We also checked every recommended restaurant, attraction and hotel to confirm it was open, and compared every quoted flight and hotel price with the live price on the booking site.

Best AI for Travel Planning Overall

Each platform was tested on its best available model with web search turned on. A platform’s overall score is the average of its scores across the eight travel tasks, with each task weighted equally. In the table below, we rank the seven platforms from highest to lowest.

Travel Planning Scores by AI Platform (September to October 2026)

Rank	AI Platform	Model Tested	Overall Score	Strongest Task
1	Google Gemini	Gemini 4 Argon	88.9	Flight Search
2	ChatGPT	GPT-6 Sol	88.2	Full Itineraries
3	Claude	Claude Opus 5.5	86.3	Visa and Entry Rules
4	Microsoft Copilot	GPT-6 Astra	84.0	Flight Search
5	Grok	Grok 4.6	80.7	Full Itineraries
6	Meta AI	Muse Spark	79.3	Restaurants and Food
7	DeepSeek	DeepSeek V4-Pro	76.4	Full Itineraries

Our researchers took three main points from this data:

• We found that Google Gemini’s lead comes from its direct access to Google Flights, Google Hotels and Google Maps, which gave it live prices, opening hours and travel times that other platforms had to look up on the web.
• ChatGPT finished 0.7 points behind Gemini and wrote the best full itineraries in the study (90.2), with clear day-by-day plans and realistic pacing.
• Claude ranked third overall and produced the fewest impossible schedules, with only 0.9 timing errors per 100 stops, but it trailed on flight search (82.3), where its fares were less often current.

Best AI for Each Travel Task

The requests in our study were split evenly across eight travel tasks, with 55 requests per task. The first table below shows the winner and runner-up for each task. The second table and the heat map that follows show every platform’s score for every task, with the top score in each column in bold.

Best AI Platform for Each Travel Task (September to October 2026)

Travel Task	Best Platform	Score	Runner-Up	Score
Full Itineraries	ChatGPT	90.2	Google Gemini	89.6
Flight Search	Google Gemini	91.8	ChatGPT	87.4
Hotels and Lodging	Google Gemini	89.3	ChatGPT	88.6
Restaurants and Food	Google Gemini	88.7	ChatGPT	87.3
Budget Trips	ChatGPT	88.5	Google Gemini	87.9
Road Trips	Google Gemini	90.4	ChatGPT	87.9
Family Travel	ChatGPT	88.4	Claude	87.8
Visa and Entry Rules	Claude	89.4	ChatGPT	87.6

Travel Planning Scores by Task and AI Platform (September to October 2026)

AI Platform	Itineraries	Flights	Hotels	Restaurants	Budget Trips	Road Trips	Family Travel	Visas
Google Gemini	89.6	91.8	89.3	88.7	87.9	90.4	87.2	86.1
ChatGPT	90.2	87.4	88.6	87.3	88.5	87.9	88.4	87.6
Claude	89.1	82.3	84.7	85.9	86.2	85.4	87.8	89.4
Microsoft Copilot	84.6	85.9	85.2	82.4	83.7	83.1	82.9	84.3
Grok	82.7	80.4	79.8	81.6	82.1	80.9	78.6	79.2
Meta AI	81.2	77.9	79.4	83.8	79.6	78.2	80.1	74.6
DeepSeek	79.4	72.1	74.8	76.2	78.9	75.3	76.4	77.8

Here is what our team took from the task-level results:

• We found that flight search produced the widest gap of any task, 19.7 points between Google Gemini (91.8) and DeepSeek (72.1). Platforms without a live flight tool often quoted fares that no longer existed.
• Claude won visa and entry rules (89.4). Judges noted that it was the most likely to flag recent rule changes and to tell travelers to confirm requirements with the official government site.
• Meta AI scored 83.8 on restaurants and food, fourth in that task and well above its overall rank, because its picks drew on popular posts from Instagram and Facebook.

Itinerary Errors: Closed Venues, Wrong Hours and Impossible Timing

An itinerary is only useful if the places in it are open and the schedule works. We checked every recommended stop in every itinerary, more than 12,000 in total, and counted four kinds of errors. The table below is sorted from fewest to most errors per 100 recommended stops.

Itinerary Errors per 100 Recommended Stops (September to October 2026)

AI Platform	Closed or Nonexistent Venues	Wrong Opening Hours	Impossible Timing	Outdated Prices	Total
Google Gemini	1.1	2.4	1.6	3.2	8.3
ChatGPT	1.8	3.1	1.4	3.9	10.2
Claude	2.3	3.6	0.9	4.4	11.2
Microsoft Copilot	2.6	3.9	2.2	4.1	12.8
Grok	3.4	4.8	2.7	5.2	16.1
Meta AI	3.9	5.1	3.3	5.8	18.1
DeepSeek	5.2	6.4	3.6	7.9	23.1

Our researchers drew three conclusions from the error data:

• We found that Google Gemini made the fewest errors overall (8.3 per 100 stops), roughly one-third as many as DeepSeek (23.1).
• Outdated prices were the most common error on every platform. Museum tickets, tours and transit passes were the items most often quoted at an old price.
• DeepSeek recommended a closed or nonexistent venue 5.2 times per 100 stops, including restaurants that had shut down more than a year earlier.

Flight and Hotel Price Accuracy

Price is the first thing most travelers check. For every flight and hotel a platform quoted, we compared its price with the live price on the airline, hotel or booking site within one hour. We also tested whether each booking link led to the right flight or property.

Price Accuracy and Booking Links by AI Platform (September to October 2026)

AI Platform	Flight Prices Within 5% of Live Fare	Hotel Prices Within 5% of Live Rate	Booking Links That Worked
Google Gemini	91.4%	89.7%	96.1%
ChatGPT	84.7%	86.2%	94.3%
Claude	71.6%	74.8%	88.6%
Microsoft Copilot	82.3%	80.4%	91.8%
Grok	66.9%	69.5%	85.2%
Meta AI	61.2%	66.3%	83.7%
DeepSeek	48.3%	52.9%	71.4%

Here is what our team took from the price data:

• We found that Google Gemini quoted 91.4% of flight prices within 5% of the live fare, 6.7 points ahead of ChatGPT.
• Fewer than half of DeepSeek’s flight prices (48.3%) were within 5% of the live fare, so travelers using it should always check the airline site before booking.
• ChatGPT’s hotel prices (86.2% accurate) came close to Gemini’s (89.7%), helped by its connected booking apps.

Best AI Models for Travel Planning, Including Free Options

Free users often get a different model than paying subscribers. We tested 10 models across the seven platforms, including each platform’s free option. The table below ranks every model we tested.

Travel Planning Scores by Model (September to October 2026)

Rank	Model	Platform	Available On	Score
1	Gemini 4 Argon	Google Gemini	Paid	88.9
2	GPT-6 Sol	ChatGPT	Paid	88.2
3	Gemini 3.8 Flash	Google Gemini	Free and paid	87.6
4	Claude Opus 5.5	Claude	Paid	86.3
5	GPT-6 Luna	ChatGPT	Free and paid	85.9
6	Claude Sonnet 5.5	Claude	Free and paid	85.7
7	GPT-6 Astra	Microsoft Copilot	Free and paid	84.0
8	Grok 4.6	Grok	Free and paid	80.7
9	Muse Spark	Meta AI	Free	79.3
10	DeepSeek V4-Pro	DeepSeek	Free	76.4

Our team took three main points from the model-level results:

• We found that Gemini 3.8 Flash is the best free AI for travel planning, scoring 87.6, only 1.3 points behind the paid Gemini 4 Argon.
• The free Gemini model outscored paid Claude Opus 5.5 (86.3), largely because of its flight and hotel results.
• Upgrading ChatGPT added 2.3 points, the biggest gain from paying of any platform in the study.
