Live Flight Fare Tracker with Aviation Stack API – Alerts via Gmail & Telegram

This automated n8n workflow continuously tracks real-time flight fare changes by querying airline APIs (e.g., Amadeus, Skyscanner). It compares new prices with historical fares and sends instant notifications to users when a fare drop is detected. All tracked data is structured and logged for audit and analysis.

Key Insights

Works post-booking to track price fluctuations for booked routes. Supports multiple fare sources for improved accuracy and comparison. Users are notified instantly via email, SMS, or Slack for high-value drops. Historical pricing data is stored for trend analysis and refund eligibility checks. Can be extended to monitor specific routes or apply airline-specific refund rules.

Workflow Process

Schedule Trigger Initiates the fare check every 6 hours.

Fetch Flight Fare Data Queries APIs (Amadeus, Skyscanner) for current flight fares.

Get Tracked Bookings Retrieves tracked routes from the internal database.

Compare Fares Detects price drops compared to original booking fares.

Update Fare History Table Logs the new fare and timestamp into the fare_tracking table.

Classify Drops Determines priority based on absolute and percentage savings.

Notify Users

Email Alerts: For all medium/high priority drops. SMS Alerts: For savings > $100 or >15%. Slack Notifications: For internal alerts and rebooking suggestions.

Log Activity Stores all sync actions and notifications in fare_alert_logs.

Usage Guide

Import** the workflow into your n8n instance. Set up** API credentials for Amadeus and Skyscanner. Configure email, SMS (Twilio), and Slack credentials. Update the booking database with valid records (with route, fare, timestamp). Set schedule frequency (e.g., every 6 hours). Review logs regularly to monitor fare alert activity and system health.

Prerequisites

Valid accounts and credentials for:

Amadeus API Skyscanner API SendGrid (or SMTP) for email Twilio for SMS Slack workspace & bot token PostgreSQL or MySQL database for fare tracking Tracked booking dataset (with routes, fares, and user contacts)

Customization Options

Adjust alert thresholds in the comparison logic (e.g., trigger only if fare drops > $50 or >10%). Add new notification channels (e.g., WhatsApp, Telegram). Extend logic to track multi-leg or roundtrip fares. Integrate airline refund APIs (where supported) to auto-initiate refund or credit requests.
