Monitor Flight Price Drops & Send Email Alerts (SerpAPI + Gmail)

This n8n workflow automates the tracking of flight prices for specified routes and dates using SerpAPI's flight search API. It runs on a scheduled basis via a Cron trigger, fetches current prices, compares them against a user-defined threshold, and immediately sends an email notification via Gmail if a price drop is detected.

Key benefits include eliminating manual price checking on websites, ensuring you never miss deals, and providing instant alerts to book at the lowest fares. It's ideal for frequent flyers, budget-conscious travelers planning trips, corporate expense managers, and travel agencies serving clients.

Setup is quick (5-10 minutes): configure origin/destination airports (e.g., JFK to SEA), outbound date (e.g., 2025-09-06), price threshold (e.g., $250), and notification email. The workflow handles the rest, querying SerpAPI periodically and emailing details like 'Flight price to Seattle dropped to $242 - Book now!'.

Prerequisites are a SerpAPI account for API access and Gmail credentials. This saves hours of daily monitoring, potentially saving hundreds on flights.
