My Airline Points Kept Changing, So I Built a Watcher

July 8, 2026 • 3 min read

Written up in October 2026. Dates are when I actually built it. Airline rewards activity isn’t a log, it’s a table that quietly edits itself. Points post late, get adjusted, sometimes vanish. I wanted a ping the moment my own account’s history changed, so I built a watcher: about 900 lines of Python with 60 unit tests. It only ever reads my own account. Don’t hash the columns, hash the meaning Each activity row gets a SHA-256 over (date, description, amount).

Rewards Account Change Watcher

A headless watcher that monitors a loyalty-program account, detects any change to its activity history (including edits and deletions of old rows), and alerts me on Telegram. It only reads my own account. About 900 lines of Python with 60 unit tests, built in three days. Architecture fetch, diff, alert, then persist. Each run captures the account’s data, diffs it against stored state, sends one message summarizing changes, and only then saves the new state.
