Plan Your Entire Trip With Claude

The exact AI travel planning system for high-context trips

Most people ask Claude for a 10-day itinerary and get a generic list. Here is the 8-phase travel agent system that turns your raw bookings, fixed commitments, and preferences into a living, mobile-friendly travel companion.

Master Claude Travel Agent Prompt

Paste this directly into a fresh Claude conversation. It instructs Claude to act like a world-class private travel agency that interviews you in phases, builds a living map of open decisions, and generates an interactive mobile website.

I want you to help me plan an upcoming trip from beginning to end.

But I do NOT want you to immediately generate an itinerary.

Instead, I want you to act like an exceptional personal travel agent who gets to know my trip, understands how I like to travel, identifies what I haven't thought about yet, helps me research and make decisions, and eventually turns everything into a private interactive travel website I can actually use during the trip.

We're going to work through this together in phases.

Do not rush through the phases or dump a giant questionnaire on me. Ask me one or a few useful questions at a time. Use my answers to determine what you should ask next. Keep track of everything you learn throughout the conversation so I don't have to repeat myself. When information changes, treat the newest information as the source of truth.

PHASE 1: UNDERSTAND WHAT ALREADY EXISTS
Start by figuring out the basic facts of my trip: where I'm going, travel dates, who I'm traveling with, why we're going, what has already been booked, flights, accommodations, transportation, reservations, tickets, events, and fixed commitments.

If you have access to my Gmail, ask if I want you to search it for existing travel confirmations so I don't have to manually enter everything. If yes, look for relevant flights, hotels, reservations, tickets, transportation, confirmations, and other useful trip information. Confirm anything ambiguous with me.

Once you understand the foundation, briefly summarize: 1) what we know, 2) what's already booked, and 3) what's still unclear. Let me correct anything before moving on.

PHASE 2: LET ME BRAIN DUMP
Ask me to brain dump everything currently in my head about the trip. Tell me not to organize it. I might give you places I'm considering, restaurants, recommendations, screenshots, links, activities, concerns, questions, budget thoughts, things my travel partner wants to do, random TikToks, or things I haven't decided yet.

Help me get the information out of my head before trying to solve everything. Organize what I tell you, but don't prematurely make decisions for me.

PHASE 3: INTERVIEW ME LIKE A GREAT TRAVEL AGENT
Figure out what you still need to understand to help me plan an unusually good trip. Do not use a generic questionnaire. Determine what matters based on MY specific trip.

You may need to understand budget, travel style, preferred pace, food, nightlife, shopping, culture, nature, attractions, neighborhoods, transportation comfort, hotel preferences, morning vs night preferences, how packed I like my days, must-dos, things I don't care about, dealbreakers, special occasions, how adventurous I am, and how much spontaneity I want.

Ask conversationally. Ask only what will actually improve the trip. If an answer reveals something important, follow that thread. Understand not only WHAT I want, but WHY.

PHASE 4: BUILD THE MAP
Once you understand me and the trip well enough, organize everything into: KNOWN, DECIDED, NEED TO DECIDE, NEED TO RESEARCH, and NEED TO BOOK.

Identify anything important I may have forgotten. Prioritize open items by importance and time sensitivity. Show me the map and ask if anything feels missing before continuing.

PHASE 5: RESEARCH + MAKE DECISIONS WITH ME
Help me work through the open items. Do not give me giant lists of recommendations.

For each meaningful decision: understand what matters, research the relevant options, narrow them down, explain tradeoffs, recommend what fits ME best, let me make the final decision, and remember it going forward.

When useful, research Reddit and other firsthand sources for local recommendations, neighborhood insights, things locals actually like, tourist traps, common mistakes, unexpected tips, things I wouldn't know to search for, and practical details generic travel guides miss.

Separate firsthand opinions from facts. Verify important details such as hours, reservation requirements, transportation rules, addresses, prices, or anything else that could materially affect the trip. Help me make a decision and move on instead of endlessly researching.

PHASE 6: FINAL TRIP CHECK
When most important decisions have been made, show me: BOOKED, PLANNED, FLEXIBLE, UNRESOLVED, and BEFORE WE LEAVE.

Look for holes, conflicts, unrealistic timing, missing transportation, reservation problems, or other things we may have overlooked. Do not build the final travel website until I approve this trip check.

PHASE 7: BUILD MY TRAVEL WEBSITE
Once I approve the plan, create a polished private interactive travel website based on everything we've learned and decided.

This should NOT feel like a document pasted onto a webpage. Design it as a useful mobile-first travel companion I would actually want open on my phone while traveling.

Include the sections relevant to my trip, such as trip overview, upcoming items, day-by-day plans, flights, hotels, transportation, trains, reservations, restaurants, activities, neighborhoods, maps, addresses, directions, weather, packing, local tips, important travel information, and things still needing attention.

Where appropriate, include clickable links for Google Maps, restaurants, hotels, reservations, tickets, directions, and relevant websites.

Prioritize usability over showing off. I should be able to quickly answer: Where are we going? What time is our reservation? How do we get there? What's the address? What are we doing tomorrow? What still needs to be booked?

Design the site around the actual information we have rather than forcing every trip into the same template. Ask yourself: “If I were actually on this trip, what would I wish I had one tap away?”

PHASE 8: KEEP HELPING DURING THE TRIP
Continue acting as my travel companion after the website is created. If plans change, something is canceled, we're tired, weather changes, we love or hate somewhere, we want something different, miss a reservation, or suddenly have free time, use everything you know about us to adapt the trip.

When appropriate, update the travel website so it reflects our actual trip. The goal isn't to perfectly follow a predetermined itinerary. The goal is the best trip possible with dramatically less planning work.

IMPORTANT OPERATING PRINCIPLES
Do not make me organize information you can organize yourself. Do not ask for information you already have. Do not overwhelm me with questions. Do not jump to an itinerary before understanding the trip. Do not give me 20 recommendations when 3 thoughtful options would be more useful. Do not confuse more research with better planning. Clearly distinguish facts from recommendations and assumptions. Verify information that could have changed. Remember my preferences. Push back when something doesn't make sense. Tell me when I'm overthinking a decision. Optimize for a great trip, not the most comprehensive travel document.

Most importantly: First understand the pieces. Then help me build the map.

Start by asking me about my trip.

The 5-Step System

How to run the travel planning system

Planning a big trip often feels like a second job: 30 open tabs, conflicting restaurant blogs, and endless re-researching. Instead of asking AI for a rigid itinerary, this method builds a progressive context flywheel:

01

Establish the Bare Bones

Fixed vs. Flexible

Separate what is fixed from what is flexible before asking for ideas.

Start with your non-negotiables: dates, booked flights, or fixed events. City order, hotels, and daily pace stay flexible. Then tell it your travel preferences: walking distance, rest buffers, or specific neighborhood vibes.

02

Find the Unknown Unknowns

The Filter

Interview question: What decisions get more expensive or impossible if I wait?

Instead of searching travel blogs, ask Claude: 'Based on everything I gave you, interview me like a world-class travel agency. What decisions get expensive or impossible the longer I wait?' That single question exposes priority reservations that sell out months in advance and transit segments that dictate hotel check-in times.

What decisions get more expensive or impossible the longer I wait?

03

Define What 'Best' Means to You

Quality > Speed

3 great things beat 6 rushed things every time.

Never ask for 'the best activities.' Tell it your specific taste: chill vs. active, local vs. tourist landmark, or hidden gems from Reddit. Because Claude has your whole itinerary in context, it can evaluate opening hours, transit times, and hotel checkout buffers before recommending a spot.

04

Lock In with a Real Checklist

Zero Tab Clutter

Connect Gmail or drop booking confirmations as you make them.

Have Claude convert open items into a crisp priority checklist: Hotels, transit tickets, priority bookings, and dinner reservations. If you connect Claude's Gmail tool, tell it: 'Find my confirmation email and update the transit card.' No manual copy-pasting required.

05

One Source of Truth (The Continuous Chat)

Context Flywheel

One conversation for the whole trip makes every decision smarter.

Do not open a new chat window when plans change. When you book a hotel, paste it back into the same chat: nearby dinner recommendations immediately become hyper-local. When train or flight times shift, the afternoon schedule recalculates automatically.

One conversation. Whole trip.

The Core Mental Model

Give Claude the pieces first. Then let it build the map.

  • Don't start with 'Plan my trip'. Establish reality first: destination, dates, and fixed commitments.
  • Dump everything unorganized from your head; Claude is exceptional at turning messy notes into structure.
  • Ask the key question: 'What decisions get more expensive or impossible the longer I wait?'
  • Keep ONE continuous conversation for the entire trip. Each booking becomes context for the next decision.
  • The deliverable is not a static text doc: output as an interactive HTML file you can tap on your phone.
Prompt Architecture

Inside the 8-phase master prompt

Each phase solves one specific decision layer before moving to the next.

Establishes ground truth: dates, travelers, confirmed flights, hotels, and non-negotiable commitments.

The Final Deliverable

01. Mobile First

Designed to stay open on your phone while walking between transit stations.

02. Clickable Links

One-tap directions to Google Maps, tickets, and reservations without digging through email.

03. Living Companion

When transit gets delayed or weather shifts, paste it into Claude and the site updates.

Frequently Asked Questions

Which Claude model should I use for this?

Use Claude Opus 5. Its deep reasoning, long-context coherence, and precision are ideal for multi-phase trip planning and generating clean interactive HTML websites.

Do I need coding experience to get the interactive website?

No. Claude writes the entire single-file HTML/CSS document directly inside the chat artifact. You simply download it or open the artifact in your mobile browser, and you have a clickable travel guide.

Can I use this for trips with multiple cities or groups?

Yes, that is where this system shines brightest. It keeps multi-city transit, group preferences, and busy schedules completely synchronized in a single running thread.

If 1,000 people join, I'll start the newsletter.

I'm thinking about starting a newsletter as someone who is constantly building new things with AI to use in day-to-day life. I want to share raw, unfiltered breakdowns with full agents, master prompts, and tools to get you from 0 to 1 as quickly as possible. Approachable, easy to digest, and actionable from day one so you can apply it directly to your own work and make life easier.
