Install the Extension

Overview

The MileIntel extension installs from the Chrome Web Store like any other extension. No manual configuration required — just install, sign in, and it starts working.

Installation Steps

1. Open Chrome (or Edge, Brave, or Arc).
2. Go to the MileIntel extension page on the Chrome Web Store.
3. Click Add to Chrome.
4. In the confirmation dialog, click Add Extension.
5. The MileIntel icon appears in your toolbar. Click it to open the popup.
6. Sign in with your Google account (the same one you use for MileIntel).

That's it. Navigate to Google Flights or a supported airline site and the extension activates automatically.

Permissions Requested

• Read and change data on specific sites — Google Flights, united.com, delta.com, aa.com, and other supported airline sites. This is how the extension overlays loyalty data on flight results.
• Storage — Saves your session token locally so you stay signed in.

The extension does NOT request access to all websites, browsing history, or other sensitive data.

Key Details

• File size is under 2 MB. Installation takes seconds.
• The extension auto-updates through the Chrome Web Store. You'll always have the latest version.
• To uninstall, right-click the extension icon > Remove from Chrome.

Tips

1. After installing, visit Google Flights and search for a route you're considering. You'll immediately see MileIntel's overlay on the results — that's the fastest way to confirm the extension is working.
