Transat Watcher

Challenge & Solution

Tracking vacation prices manually is tedious — you have to remember to check, and by the time you do, the deal may already be gone. Air Transat's site has no built-in price alerts, so I built one myself.

The watcher handles the whole problem end-to-end:

• Automated Hourly Checks: Polls Air Transat's public API every hour via a scheduled GitLab CI pipeline — no server to maintain and no cost.
• Instant Price Alerts: Sends an email the moment any watched hotel's price drops or rises, with the exact amount and direction of the change.
• Daily Morning Summary: Delivers a digest email each morning with current prices across all watched hotels, so you stay informed without needing to check the site.
• Multi-Hotel Support: Watch as many hotels and room types simultaneously as you want — just add entries to a simple config list.
• Price History Database: SQLite stores every price check locally, enabling comparisons and trend analysis over time.
