AI Travel Agent with LangGraph | Build Smart Assistants for Flights & Hotels

This project demonstrates building a smart AI travel assistant powered by LangGraph. It leverages multiple large language models (LLMs) to handle travel-related tasks such as finding flights, booking hotels, and generating personalized travel itineraries. The agent features stateful interactions, remembering past conversations, and includes a human-in-the-loop mechanism allowing users to review and control critical actions like sending travel details via email. The chatbot integrates APIs like Google Flights and Google Hotels to fetch travel data, and it automates email delivery using SendGrid for seamless user experience. The project aims to provide a practical example of building production-ready AI agents for travel planning with dynamic LLM usage and full user control.
