An AI Travel Agent That Literally Does Everything

Education

Introduction

Imagine never having to lift a finger to plan a trip again. What if the perfect travel agent was right in your pocket and cost you nothing? I built an AI travel agent that does literally everything—it finds flights, books hotels, plans activities—all tailored to your budget. You simply tell the agent when you want to travel, and bam! It's all done.

How It Works

In this article, not only will I show you how it works, but I’m also sharing the entire code and process so you can copy, tweak, and use it for your own trips. We're going to use Crew AI for agent creation, React for a custom front end, and Python for the back end. I’ll guide you through integrating external APIs like Amadeus and GetYourGuide. This isn't just a demo; it's a live build you can replicate.

Gathering User Information

First, we want to gather input from the user, which includes:

  • Budget
  • Destination
  • Travel dates
  • Interests

Once the user enters this information, the agent will search for flights, hotels, and activities. Finally, all of these will be tied into a comprehensive itinerary, with different versions that you can choose from based on your budget.

Setting Up the Backend

The initial step involves setting up our backend using Crew AI. First, create a new project and use Python (the language closest to AI) to build our agents. Upon installation, we’ll define the configurations in the config.yaml file. For this project, we’ll also create custom tools to make API requests for flights, hotels, and activities.

Frontend Development

Moving to the front end, you'll set up a Next.js application. Create a new repository, and you can use npm or Yarn to manage package installations. We will set up forms to collect user data, including the destination, travel dates, and budget.

Connecting Frontend and Backend

Once both the backend and frontend are set up, the next step is connecting the two. This involves handling form submissions and managing state to ensure all user inputs are captured correctly. This is where we encounter errors that we can troubleshoot using real-time data logging.

API Integration

Next, we’ll integrate several APIs:

  • Flights: Using Amadeus to fetch flight availability.
  • Hotels: Using a service like Booking.com for hotel booking.
  • Activities: Using GetYourGuide to find local activities.

Creating Itineraries

With APIs in place, we can represent the user’s entire trip, showing options for flights, hotels, and activities in an organized manner. The AI takes the user’s preferences into account—such as interests and budget—to generate a tailored itinerary.

Testing and Validating

Finally, we’ll continuously test and validate our AI agent to ensure it functions as expected. We can use real data inputs to refine our offerings and optimize the travel planning experience.
