This project provides a daily-updated open dataset of observed flight fares across 86,745 city pairs, capturing price distributions rather than single snapshots. It enables price trend analysis and 'good deal' judgments that live search engines cannot offer, and includes research tables and a free MCP server for programmatic access.
