Delta Price Tracker

A free desktop app that watches your booked Delta flights and emails you when the price drops. Because airlines do not tell you when your flight gets cheaper.

The Problem

Delta lets you rebook at a lower price and keep the difference as an eCredit. But they are not going to tell you when the price drops. You have to check manually, over and over, for every flight you have booked. Nobody does that consistently, so most people leave money on the table.

Delta Price Tracker does the checking for you. You add your flight details, and the app monitors Delta.com daily, in the background, and sends you an email the moment the price drops below what you paid.

How It Works

Installation

On Windows, download the installer EXE and run it. On Mac, download the zip and run the install script. The app handles all dependencies automatically on first launch, including the browser automation tool it uses to check Delta.com. No Python knowledge or command line experience needed.

The tracker is limited to 8 flights at a time to avoid triggering rate limits on Delta.com. Each flight is checked roughly 20 minutes apart, so a full cycle for 8 flights takes about 2.5 hours. You can archive completed trips to make room for new ones.

Privacy and Data

Everything runs locally on your computer. The only outbound connections are to Delta.com (to check prices) and your Gmail SMTP server (to send alerts). Your flight data is stored in a local SQLite database on your machine. Nothing is sent to any external server or cloud service.

If you are also tracking purchases on Amazon, the Amazon Price Tracker works on the same principle: local monitoring, email alerts, no cloud dependency.
