Search Google Flights

punitarani/fli

Connects Claude directly to Google Flights through reverse-engineered API calls, no web scraping involved. Exposes two tools: search_flights for specific dates with granular filters (cabin class, layover windows, airline alliances, departure time ranges), and search_dates for finding the cheapest days to fly across a flexible window. Reach for this when you need Claude to help plan trips, compare routes, or answer "when's the cheapest week to fly to Tokyo" without opening a browser. Handles multi-city searches, supports currency and locale preferences, and includes sorting by price, duration, or arrival time. Built with rate limiting and retries baked in, so it won't hammer the API.

🛫 Fli - Flight Search MCP Server and Library

Ask DeepWiki

A powerful Python library that provides programmatic access to Google Flights data with an elegant CLI interface. Search flights, find the best deals, and filter results with ease.

🚀 What makes fli special? Unlike other flight search libraries that rely on web scraping, Fli directly interacts with Google Flights' API through reverse engineering. This means:

  • Fast: Direct API access means faster, more reliable results
  • Zero Scraping: No HTML parsing, no browser automation, just pure API interaction
  • Reliable: Less prone to breaking from UI changes
  • Modular: Extensible architecture for easy customization and integration
