Flight Ledger

Flight Ledger is a personal ledger for tracking flights, expenses, and airline status without requiring sign-up or a backend server. Designed for frequent flyers, especially those in the United Airlines ecosystem, it lets you reconcile flight costs against MileagePlus postings and monitor Premier status qualification. The app stores all data locally using SQLite and WebAssembly, with optional Google Drive sync for multi-device access.

Key features include cost-per-mile calculations, United-specific metrics like PQP and PQF tracking, lifetime miles monitoring, and the ability to categorize expenses as out-of-pocket or reimbursed. The app accepts imports from MileagePlus activity CSVs, email receipts, and flight tracking apps. The maker says it was built with Claude Code.
