Monitor Flight Price Drops and Send Email Alerts with SerpAPI and Gmail

Description

Problem:
🚨It is difficult to manually track changing flight prices and quickly identify the best time to book a ticket. Many travelers miss deals or spend too much time monitoring fares for their specific routes and travel dates.

Prerequisites:

Gmail or another email service account (for email alerts)

This would be helpful for:
Frequent flyers wanting to book flights at the lowest price
Budget travelers planning trips in advance
Corporate travelers managing travel expenses
Travel agencies monitoring deals for clients

Step-by-step workflow:
Takes 5-10 minutes to set up

Set your preferred flight route and travel date
Choose the price alert threshold
Automatically monitor flight prices at your selected interval
Get notified by email when a price drop is detected
