What it solves

LetsFG addresses the inefficiency and price inflation of traditional travel booking sites. It eliminates the need to manually compare dozens of tabs, avoids price tracking that increases costs when you search repeatedly, and bypasses the extra fees often added by online travel agencies (OTAs).

How it works

It provides a server-side engine that scans airlines and travel providers globally to return stable, real-time pricing. Users can integrate this engine into AI agents (via MCP servers), use a CLI/SDK, or call the API directly. Once a user connects their account (a one-time tap, no card required for searching), they can perform free searches. When booking, the system holds the fare on the user's card and uses a dedicated booking agent to secure the ticket, providing a real airline PNR (Passenger Name Record).

Who it’s for

This project is for developers building AI agents (such as those using Claude, ChatGPT, Cursor, or Windsurf) who want to add flight and hotel booking capabilities, as well as power users who want to automate travel searches via scripts or CLI tools.

Highlights

• Stable Pricing: Returns consistent prices regardless of how often you search, avoiding surge pricing and cookie-based tracking.
• AI Integration: Supports Model Context Protocol (MCP) for easy integration into major AI chat interfaces.
• Real Bookings: Handles the full booking lifecycle, resulting in actual airline PNRs rather than just redirects.
• Free Search: Offers free programmatic flight search (PFS) for agents and scripts via a simple OAuth-style connection flow.
