n8n Flight Price Tracker: Apify Google Flights → Sheets + Telegram Alerts

Track Google Flights prices automatically—and get Telegram alerts the moment a deal drops

This n8n workflow runs daily to check flight prices using the Apify Google Flights actor, logs results to Google Sheets, and sends a Telegram message when the lowest fare falls below your set threshold and is meaningfully cheaper than the last alert.

What this workflow does

• Schedules a daily check at 7am and loads your flight search inputs: route, dates, passengers, cabin class, currency, and alert thresholds.
• Fetches live offers via the Apify Google Flights API to retrieve matching flight offers.
• Finds the best deal by parsing returned offers to identify the lowest price, extracting key flight details, and generating a Google Flights booking link.
• Alerts only on meaningful drops: if the lowest price is at or below your threshold, the workflow reads the previous notification data from Google Sheets and compares prices.
• Uses a re-alert buffer to prevent spam—Telegram is sent only if the price is lower than the last notified price by at least your configured amount.
• Updates your log: sends a detailed Telegram message and upserts the latest notified price and timestamps back into Google Sheets.

Use cases

• Monitor a frequently traveled route and buy only when fares hit your target.
• Track seasonal price drops for business travel (specific cabin class + currency).
• Run a lightweight SaaS-style “deal finder” for yourself or a small team without manual searches.

Technical details

• Nodes/logic used: if, set, code, http request, telegram, sticky note.
• Integrations: Apify (Google Flights actor via HTTP request with Apify API token), Google Sheets (Service Account log storage), and Telegram (best-deal alert messages).

Perfect for n8n users and automation engineers who want reliable flight price tracking with clean history and noise-free alerts.
