# Multiagent-flight-booking-system

A Google ADK–powered prototype flight booking system with multi-agent orchestration, FastAPI microservices, Streamlit UI, and Docker. Demonstrates smart, modular, cloud-ready automation for search and booking workflows.

Multiagent Flight Booking System (Prototype)

A cloud-ready, Docker-orchestrated multi-agent flight booking prototype powered by Google ADK, FastAPI microservices, Streamlit UI, and agent-driven orchestration. This system demonstrates a modern, modular, and production-style architecture for automated flight search and booking workflows.



  

  

  

  

  

  

  

  

  

  

  

  

  

  



Project Overview:

This prototype showcases a scalable multi-agent architecture where each agent handles a specialized responsibility:

Search Agent → Handles flight lookup logic

Booking Agent → Simulates booking and confirmation

Orchestrator Agent → Coordinates search and booking workflows

Streamlit UI → User-facing interface for interacting with the system

The system simulates real airline processes using microservices and agent coordination through Google ADK.

Architecture :

The application is composed of four containerized microservices:

    Service	           Port	          Description

Search Service	       8001	       Simulated flight search

Booking Service	       8002        Booking + confirmation

Orchestrator Service	 8004	       Multi-agent logic + routing

UI (Streamlit)	       8501	       Frontend interface

All services communicate through Docker’s internal DNS.

Tech Stack : 

FastAPI (microservices)

Streamlit (web UI)

Google ADK (multi-agent orchestration)

Python 3.10

Docker + Docker Compose

httpx (service-to-service communication)

Run the System with Docker Compose :

Ensure Docker Desktop is installed, then from the project root:

docker compose up --build

The UI will be available at: http://localhost:8501

All services start automatically and communicate internally.

🧪 Features :

✔ Multi-agent workflow using Google ADK

✔ Microservices architecture

✔ Dockerized and cloud-ready

✔ Mocked real-world flight search + booking

✔ Single-command deployment via docker-compose

✔ Clean service boundaries + REST APIs

🧩 Future Enhancements :

Integrate real airline APIs (Amadeus / Skyscanner)

Add PostgreSQL for persistent bookings

Implement authentication

Deploy to Google Cloud Run or Railway

Add async background booking jobs

Status : This is a prototype, designed to demonstrate system architecture, agent coordination, and containerized deployment.
